Returns promises that can be awaited for batch results\n * - Built-in retry support via AsyncRetryer integration\n * - Abort support to cancel in-flight batch executions\n * - Cancel support to prevent pending batches from starting\n * - Comprehensive error handling with onError callbacks and throwOnError control\n * - Detailed execution tracking (success/error/settle counts)\n *\n * The sync Batcher is lighter weight and simpler when you don't need async features,\n * return values, or execution control.\n *\n * What is Batching?\n * Batching is a technique for grouping multiple operations together to be processed as a single unit.\n *\n * The AsyncBatcher provides a flexible way to implement async batching with configurable:\n * - Maximum batch size (number of items per batch)\n * - Time-based batching (process after X milliseconds)\n * - Custom batch processing logic via getShouldExecute\n * - Event callbacks for monitoring batch operations\n * - Error handling for failed batch operations\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error, the batch of items that failed, and batcher instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the AsyncBatcher instance\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async batcher\n * - Use `onSuccess` callback to react to successful batch execution and implement custom logic\n * - Use `onError` callback to react to batch execution errors and implement custom error handling\n * - Use `onSettled` callback to react to batch execution completion (success or error) and implement custom logic\n * - Use `onExecute` callback to react to batch execution and implement custom logic\n * - Use `onItemsChange` callback to react to items being added or removed from the batcher\n * - The state includes total items processed, success/error counts, and execution status\n * - State can be accessed via `asyncBatcher.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `asyncBatcher.state`\n *\n * @example\n * ```ts\n * const batcher = new AsyncBatcher<number>(\n *   async (items) => {\n *     const result = await processItems(items);\n *     console.log('Processing batch:', items);\n *     return result;\n *   },\n *   {\n *     maxSize: 5,\n *     wait: 2000,\n *     onSuccess: (result) => console.log('Batch succeeded:', result),\n *     onError: (error) => console.error('Batch failed:', error)\n *   }\n * );\n *\n * batcher.addItem(1);\n * batcher.addItem(2);\n * // After 2 seconds or when 5 items are added, whichever comes first,\n * // the batch will be processed and the result will be available\n * // batcher.execute() // manually trigger a batch\n * ```\n */\nexport class AsyncBatcher<TValue> {\n  readonly store: Store<Readonly<AsyncBatcherState<TValue>>> = new Store(\n    getDefaultAsyncBatcherState<TValue>(),\n  )\n  key: string | undefined\n  options: AsyncBatcherOptionsWithOptionalCallbacks<TValue>\n  asyncRetryers = new Map<\n    number,\n    AsyncRetryer<(items: Array<TValue>) => Promise<any>>\n  >()\n  #timeoutId: NodeJS.Timeout | null = null\n\n  constructor(\n    public fn: (items: Array<TValue>) => Promise<any>,\n    initialOptions: AsyncBatcherOptions<TValue>,\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n      throwOnError: initialOptions.throwOnError ?? !initialOptions.onError,\n    }\n    this.#setState(this.options.initialState ?? {})\n\n    if (this.key) {\n      pacerEventClient.on('d-AsyncBatcher', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(\n          event.payload.store.state as Partial<AsyncBatcherState<TValue>>,\n        )\n        this.setOptions(\n          event.payload.options as Partial<AsyncBatcherOptions<TValue>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the async batcher options\n   */\n  setOptions = (newOptions: Partial<AsyncBatcherOptions<TValue>>): void => {\n    this.options = { ...this.options, ...newOptions }\n  }\n\n  #setState = (newState: Partial<AsyncBatcherState<TValue>>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const { isExecuting, isPending, items } = combinedState\n      const size = items.length\n      const isEmpty = size === 0\n      return {\n        ...combinedState,\n        isEmpty,\n        size,\n        status: isExecuting\n          ?

Returns promises that can be awaited for batch results\n * - Built-in retry support via AsyncRetryer integration\n * - Abort support to cancel in-flight batch executions\n * - Cancel support to prevent pending batches from starting\n * - Comprehensive error handling with onError callbacks and throwOnError control\n * - Detailed execution tracking (success/error/settle counts)\n *\n * The sync Batcher is lighter weight and simpler when you don't need async features,\n * return values, or execution control.\n *\n * What is Batching?\n * Batching is a technique for grouping multiple operations together to be processed as a single unit.\n *\n * The AsyncBatcher provides a flexible way to implement async batching with configurable:\n * - Maximum batch size (number of items per batch)\n * - Time-based batching (process after X milliseconds)\n * - Custom batch processing logic via getShouldExecute\n * - Event callbacks for monitoring batch operations\n * - Error handling for failed batch operations\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error, the batch of items that failed, and batcher instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the AsyncBatcher instance\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async batcher\n * - Use `onSuccess` callback to react to successful batch execution and implement custom logic\n * - Use `onError` callback to react to batch execution errors and implement custom error handling\n * - Use `onSettled` callback to react to batch execution completion (success or error) and implement custom logic\n * - Use `onExecute` callback to react to batch execution and implement custom logic\n * - Use `onItemsChange` callback to react to items being added or removed from the batcher\n * - The state includes total items processed, success/error counts, and execution status\n * - State can be accessed via `asyncBatcher.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `asyncBatcher.state`\n *\n * @example\n * ```ts\n * const batcher = new AsyncBatcher<number>(\n *   async (items) => {\n *     const result = await processItems(items);\n *     console.log('Processing batch:', items);\n *     return result;\n *   },\n *   {\n *     maxSize: 5,\n *     wait: 2000,\n *     onSuccess: (result) => console.log('Batch succeeded:', result),\n *     onError: (error) => console.error('Batch failed:', error)\n *   }\n * );\n *\n * batcher.addItem(1);\n * batcher.addItem(2);\n * // After 2 seconds or when 5 items are added, whichever comes first,\n * // the batch will be processed and the result will be available\n * // batcher.execute() // manually trigger a batch\n * ```\n */\nexport class AsyncBatcher<TValue> {\n  readonly store: Store<Readonly<AsyncBatcherState<TValue>>> = new Store(\n    getDefaultAsyncBatcherState<TValue>(),\n  )\n  key: string | undefined\n  options: AsyncBatcherOptionsWithOptionalCallbacks<TValue>\n  asyncRetryers = new Map<\n    number,\n    AsyncRetryer<(items: Array<TValue>) => Promise<any>>\n  >()\n  #timeoutId: ReturnType<typeof setTimeout> | null = null\n\n  constructor(\n    public fn: (items: Array<TValue>) => Promise<any>,\n    initialOptions: AsyncBatcherOptions<TValue>,\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n      throwOnError: initialOptions.throwOnError ?? !initialOptions.onError,\n    }\n    this.#setState(this.options.initialState ?? {})\n\n    if (this.key) {\n      pacerEventClient.on('d-AsyncBatcher', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(\n          event.payload.store.state as Partial<AsyncBatcherState<TValue>>,\n        )\n        this.setOptions(\n          event.payload.options as Partial<AsyncBatcherOptions<TValue>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the async batcher options\n   */\n  setOptions = (newOptions: Partial<AsyncBatcherOptions<TValue>>): void => {\n    this.options = { ...this.options, ...newOptions }\n  }\n\n  #setState = (newState: Partial<AsyncBatcherState<TValue>>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const { isExecuting, isPending, items } = combinedState\n      const size = items.length\n      const isEmpty = size === 0\n      return {\n        ...combinedState,\n        isEmpty,\n        size,\n        status: isExecuting\n          ?

`maxSize`: Maximum number of items per batch (default: Infinity)\n * - `wait`: Time to wait before processing batch (default: Infinity)\n * - `getShouldExecute`: Custom logic to trigger batch processing\n * - `asyncRetryerOptions`: Configure retry behavior for batch executions\n * - `started`: Whether to start processing immediately (default: true)\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error, the batch of items that failed, and batcher instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the underlying AsyncBatcher instance\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async batcher\n * - Use `onSuccess` callback to react to successful batch execution and implement custom logic\n * - Use `onError` callback to react to batch execution errors and implement custom error handling\n * - Use `onSettled` callback to react to batch execution completion (success or error) and implement custom logic\n * - Use `onItemsChange` callback to react to items being added or removed from the batcher\n * - The state includes total items processed, success/error counts, and execution status\n * - State can be accessed via the underlying AsyncBatcher instance's `store.state` property\n * - When using framework adapters (React/Solid), state is accessed from the hook's state property\n *\n * @example\n * ```ts\n * const batchItems = asyncBatch<number>(\n *   async (items) => {\n *     const result = await processApiCall(items);\n *     console.log('Processing:', items);\n *     return result;\n *   },\n *   {\n *     maxSize: 3,\n *     wait: 1000,\n *     onSuccess: (result) => console.log('Batch succeeded:', result),\n *     onError: (error) => console.error('Batch failed:', error)\n *   }\n * );\n *\n * batchItems(1);\n * batchItems(2);\n * batchItems(3); // Triggers batch processing\n * ```\n */\nexport function asyncBatch<TValue>(\n  fn: (items: Array<TValue>) => Promise<any>,\n  options: AsyncBatcherOptions<TValue>,\n) {\n  const batcher = new AsyncBatcher<TValue>(fn, options)\n  return batcher.addItem\n}\n"],"mappings":";;;;;;;AAkEA,SAAS,8BAAiE;AACxE,QAAO;EACL,YAAY;EACZ,cAAc;EACd,aAAa,EAAE;EACf,SAAS;EACT,aAAa;EACb,WAAW;EACX,OAAO,EAAE;EACT,YAAY;EACZ,aAAa;EACb,MAAM;EACN,QAAQ;EACR,cAAc;EACd,qBAAqB;EACrB,kBAAkB;EACnB;;;;;;AAqFH,SAAgB,oBAKd,SAA6B;AAC7B,QAAO;;AAaT,MAAM,iBAAgE;CACpE,qBAAqB,EACnB,aAAa,GACd;CACD,wBAAwB;CACxB,SAAS;CACT,SAAS;CACT,cAAc;CACd,MAAM;CACP;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AAqED,IAAa,eAAb,MAAkC;CAUhC,aAAmD;CAEnD,YACE,AAAO,IACP,gBACA;EAFO;eAZoD,IAAIA,sBAC/D,6BAAqC,CACtC;uCAGe,IAAI,KAGjB;qBA+BW,eAA2D;AACvE,QAAK,UAAU;IAAE,GAAG,KAAK;IAAS,GAAG;IAAY;;iBAwCzC,OAAO,SAA+B;AAC9C,SAAKC,SAAU;IACb,OAAO,CAAC,GAAG,KAAK,MAAM,MAAM,OAAO,KAAK;IACxC,WAAW,KAAK,QAAQ,SAAS;IAClC,CAAC;AACF,QAAK,QAAQ,gBAAgB,KAAK;AAMlC,OAHE,KAAK,MAAM,MAAM,MAAM,UAAU,KAAK,QAAQ,WAC9C,KAAK,QAAQ,iBAAiB,KAAK,MAAM,MAAM,OAAO,KAAK,CAG3D,QAAO,MAAM,MAAKC,SAAU;YACnB,KAAK,QAAQ,SAAS,UAAU;AACzC,UAAKC,cAAe;AACpB,UAAKC,YAAa,iBAAiB,MAAKF,SAAU,EAAE,MAAKG,SAAU,CAAC;AACpE,UAAM,IAAI,SAAS,YAAY,WAAW,SAAS,MAAKA,SAAU,CAAC,CAAC;;;eAmEhE,YAA0B;AAChC,SAAKF,cAAe;AACpB,UAAO,MAAM,MAAKD,SAAU;;4BAMM;AAClC,UAAO,CAAC,GAAG,KAAK,MAAM,MAAM,MAAM;;+BAGG;AACrC,UAAO,CAAC,GAAG,KAAK,MAAM,MAAM,YAAY;;qBAatB;AAClB,SAAKD,SAAU;IAAE,OAAO,EAAE;IAAE,aAAa,EAAE;IAAE,WAAW;IAAO,CAAC;;yBA2BhD,iBAA8C;GAC9D,MAAM,QAAQ,gBAAgB,KAAK,MAAM,MAAM;AAE/C,UADgB,KAAK,cAAc,IAAI,MAAM,EAC7B,gBAAgB,IAAI;;qBAQlB;AAClB,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;AACxD,QAAK,cAAc,OAAO;AAC1B,SAAKA,SAAU,EACb,aAAa,OACd,CAAC;;sBAQiB;AACnB,SAAKE,cAAe;AACpB,SAAKF,SAAU,EACb,WAAW,OACZ,CAAC;;qBAMgB;AAClB,SAAKA,SAAU,6BAAqC,CAAC;AACrD,QAAK,QAAQ,gBAAgB,KAAK;AAClC,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;;AA/OxD,OAAK,MAAM,eAAe;AAC1B,OAAK,UAAU;GACb,GAAG;GACH,GAAG;GACH,cAAc,eAAe,gBAAgB,CAAC,eAAe;GAC9D;AACD,QAAKA,SAAU,KAAK,QAAQ,gBAAgB,EAAE,CAAC;AAE/C,MAAI,KAAK,IACP,uCAAiB,GAAG,mBAAmB,UAAU;AAC/C,OAAI,MAAM,QAAQ,QAAQ,KAAK,IAAK;AACpC,SAAKA,SACH,MAAM,QAAQ,MAAM,MACrB;AACD,QAAK,WACH,MAAM,QAAQ,QACf;IACD;;CAWN,aAAa,aAAuD;AAClE,OAAK,MAAM,UAAU,UAAU;GAC7B,MAAM,gBAAgB;IACpB,GAAG;IACH,GAAG;IACJ;GACD,MAAM,EAAE,aAAa,WAAW,UAAU;GAC1C,MAAM,OAAO,MAAM;GACnB,MAAM,UAAU,SAAS;AACzB,UAAO;IACL,GAAG;IACH;IACA;IACA,QAAQ,cACJ,cACA,YACE,YACA,UACE,SACA;IACT;IACD;AACF,kCAAW,gBAAgB,KAAK;;CAGlC,iBAAyB;AACvB,SAAOK,mCAAqB,KAAK,QAAQ,MAAM,KAAK;;;;;;;;;;;;;;CA2CtD,WAAW,YAA0B;AACnC,MAAI,KAAK,MAAM,MAAM,MAAM,WAAW,EACpC;EAGF,MAAM,sBAAsB,KAAK,MAAM,MAAM,eAAe;EAC5D,MAAM,QAAQ,KAAK,cAAc;AACjC,OAAK,OAAO;AACZ,OAAK,QAAQ,gBAAgB,KAAK;AAElC,QAAKL,SAAU;GAAE,aAAa;GAAM,cAAc;GAAqB,CAAC;AAExE,MAAI;GACF,MAAM,sBAAsB,IAAIM,mCAC9B,KAAK,IACL,KAAK,QAAQ,oBACd;AACD,QAAK,cAAc,IAAI,qBAAqB,oBAAoB;GAChE,MAAM,SAAS,MAAM,oBAAoB,QAAQ,MAAM;AACvD,SAAKN,SAAU;IACb,qBACE,KAAK,MAAM,MAAM,sBAAsB,MAAM;IAC/C,YAAY;IACZ,cAAc,KAAK,MAAM,MAAM,eAAe;IAC/C,CAAC;AACF,QAAK,QAAQ,YAAY,QAAQ,OAAO,KAAK;AAC7C,UAAO;WACA,OAAO;AACd,SAAKA,SAAU;IACb,YAAY,KAAK,MAAM,MAAM,aAAa;IAC1C,aAAa,CAAC,GAAG,KAAK,MAAM,MAAM,aAAa,GAAG,MAAM;IACxD,kBAAkB,KAAK,MAAM,MAAM,mBAAmB,MAAM;IAC7D,CAAC;AACF,QAAK,QAAQ,UAAU,OAAgB,OAAO,KAAK;AACnD,OAAI,KAAK,QAAQ,aACf,OAAM;AAER;YACQ;AACR,QAAK,cAAc,OAAO,oBAAoB;AAC9C,SAAKA,SAAU;IACb,aAAa;IACb,aAAa,KAAK,MAAM,MAAM,cAAc;IAC7C,CAAC;AACF,QAAK,QAAQ,YAAY,OAAO,KAAK;;;CAuBzC,sBAA4B;AAC1B,MAAI,MAAKG,WAAY;AACnB,gBAAa,MAAKA,UAAW;AAC7B,SAAKA,YAAa;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AA4IxB,SAAgB,WACd,IACA,SACA;AAEA,QADgB,IAAI,aAAqB,IAAI,QAAQ,CACtC"}

Returns promises that can be awaited for batch results\n * - Built-in retry support via AsyncRetryer integration\n * - Abort support to cancel in-flight batch executions\n * - Cancel support to prevent pending batches from starting\n * - Comprehensive error handling with onError callbacks and throwOnError control\n * - Detailed execution tracking (success/error/settle counts)\n *\n * The sync batch function is lighter weight and simpler when you don't need async features,\n * return values, or execution control.\n *\n * What is Batching?\n * Batching is a technique for grouping multiple operations together to be processed as a single unit.\n *\n * Configuration Options:\n * - `maxSize`: Maximum number of items per batch (default: Infinity)\n * - `wait`: Time to wait before processing batch (default: Infinity)\n * - `getShouldExecute`: Custom logic to trigger batch processing\n * - `asyncRetryerOptions`: Configure retry behavior for batch executions\n * - `started`: Whether to start processing immediately (default: true)\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error, the batch of items that failed, and batcher instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the underlying AsyncBatcher instance\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async batcher\n * - Use `onSuccess` callback to react to successful batch execution and implement custom logic\n * - Use `onError` callback to react to batch execution errors and implement custom error handling\n * - Use `onSettled` callback to react to batch execution completion (success or error) and implement custom logic\n * - Use `onItemsChange` callback to react to items being added or removed from the batcher\n * - The state includes total items processed, success/error counts, and execution status\n * - State can be accessed via the underlying AsyncBatcher instance's `store.state` property\n * - When using framework adapters (React/Solid), state is accessed from the hook's state property\n *\n * @example\n * ```ts\n * const batchItems = asyncBatch<number>(\n *   async (items) => {\n *     const result = await processApiCall(items);\n *     console.log('Processing:', items);\n *     return result;\n *   },\n *   {\n *     maxSize: 3,\n *     wait: 1000,\n *     onSuccess: (result) => console.log('Batch succeeded:', result),\n *     onError: (error) => console.error('Batch failed:', error)\n *   }\n * );\n *\n * batchItems(1);\n * batchItems(2);\n * batchItems(3); // Triggers batch processing\n * ```\n */\nexport function asyncBatch<TValue>(\n  fn: (items: Array<TValue>) => Promise<any>,\n  options: AsyncBatcherOptions<TValue>,\n) {\n  const batcher = new AsyncBatcher<TValue>(fn, options)\n  return batcher.addItem\n}\n"],"mappings":";;;;;;AAkEA,SAAS,8BAAiE;AACxE,QAAO;EACL,YAAY;EACZ,cAAc;EACd,aAAa,EAAE;EACf,SAAS;EACT,aAAa;EACb,WAAW;EACX,OAAO,EAAE;EACT,YAAY;EACZ,aAAa;EACb,MAAM;EACN,QAAQ;EACR,cAAc;EACd,qBAAqB;EACrB,kBAAkB;EACnB;;;;;;AAqFH,SAAgB,oBAKd,SAA6B;AAC7B,QAAO;;AAaT,MAAM,iBAAgE;CACpE,qBAAqB,EACnB,aAAa,GACd;CACD,wBAAwB;CACxB,SAAS;CACT,SAAS;CACT,cAAc;CACd,MAAM;CACP;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AAqED,IAAa,eAAb,MAAkC;CAUhC,aAAoC;CAEpC,YACE,AAAO,IACP,gBACA;EAFO;eAZoD,IAAI,MAC/D,6BAAqC,CACtC;uCAGe,IAAI,KAGjB;qBA+BW,eAA2D;AACvE,QAAK,UAAU;IAAE,GAAG,KAAK;IAAS,GAAG;IAAY;;iBAwCzC,OAAO,SAA+B;AAC9C,SAAKA,SAAU;IACb,OAAO,CAAC,GAAG,KAAK,MAAM,MAAM,OAAO,KAAK;IACxC,WAAW,KAAK,QAAQ,SAAS;IAClC,CAAC;AACF,QAAK,QAAQ,gBAAgB,KAAK;AAMlC,OAHE,KAAK,MAAM,MAAM,MAAM,UAAU,KAAK,QAAQ,WAC9C,KAAK,QAAQ,iBAAiB,KAAK,MAAM,MAAM,OAAO,KAAK,CAG3D,QAAO,MAAM,MAAKC,SAAU;YACnB,KAAK,QAAQ,SAAS,UAAU;AACzC,UAAKC,cAAe;AACpB,UAAKC,YAAa,iBAAiB,MAAKF,SAAU,EAAE,MAAKG,SAAU,CAAC;AACpE,UAAM,IAAI,SAAS,YAAY,WAAW,SAAS,MAAKA,SAAU,CAAC,CAAC;;;eAmEhE,YAA0B;AAChC,SAAKF,cAAe;AACpB,UAAO,MAAM,MAAKD,SAAU;;4BAMM;AAClC,UAAO,CAAC,GAAG,KAAK,MAAM,MAAM,MAAM;;+BAGG;AACrC,UAAO,CAAC,GAAG,KAAK,MAAM,MAAM,YAAY;;qBAatB;AAClB,SAAKD,SAAU;IAAE,OAAO,EAAE;IAAE,aAAa,EAAE;IAAE,WAAW;IAAO,CAAC;;yBA2BhD,iBAA8C;GAC9D,MAAM,QAAQ,gBAAgB,KAAK,MAAM,MAAM;AAE/C,UADgB,KAAK,cAAc,IAAI,MAAM,EAC7B,gBAAgB,IAAI;;qBAQlB;AAClB,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;AACxD,QAAK,cAAc,OAAO;AAC1B,SAAKA,SAAU,EACb,aAAa,OACd,CAAC;;sBAQiB;AACnB,SAAKE,cAAe;AACpB,SAAKF,SAAU,EACb,WAAW,OACZ,CAAC;;qBAMgB;AAClB,SAAKA,SAAU,6BAAqC,CAAC;AACrD,QAAK,QAAQ,gBAAgB,KAAK;AAClC,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;;AA/OxD,OAAK,MAAM,eAAe;AAC1B,OAAK,UAAU;GACb,GAAG;GACH,GAAG;GACH,cAAc,eAAe,gBAAgB,CAAC,eAAe;GAC9D;AACD,QAAKA,SAAU,KAAK,QAAQ,gBAAgB,EAAE,CAAC;AAE/C,MAAI,KAAK,IACP,kBAAiB,GAAG,mBAAmB,UAAU;AAC/C,OAAI,MAAM,QAAQ,QAAQ,KAAK,IAAK;AACpC,SAAKA,SACH,MAAM,QAAQ,MAAM,MACrB;AACD,QAAK,WACH,MAAM,QAAQ,QACf;IACD;;CAWN,aAAa,aAAuD;AAClE,OAAK,MAAM,UAAU,UAAU;GAC7B,MAAM,gBAAgB;IACpB,GAAG;IACH,GAAG;IACJ;GACD,MAAM,EAAE,aAAa,WAAW,UAAU;GAC1C,MAAM,OAAO,MAAM;GACnB,MAAM,UAAU,SAAS;AACzB,UAAO;IACL,GAAG;IACH;IACA;IACA,QAAQ,cACJ,cACA,YACE,YACA,UACE,SACA;IACT;IACD;AACF,aAAW,gBAAgB,KAAK;;CAGlC,iBAAyB;AACvB,SAAO,qBAAqB,KAAK,QAAQ,MAAM,KAAK;;;;;;;;;;;;;;CA2CtD,WAAW,YAA0B;AACnC,MAAI,KAAK,MAAM,MAAM,MAAM,WAAW,EACpC;EAGF,MAAM,sBAAsB,KAAK,MAAM,MAAM,eAAe;EAC5D,MAAM,QAAQ,KAAK,cAAc;AACjC,OAAK,OAAO;AACZ,OAAK,QAAQ,gBAAgB,KAAK;AAElC,QAAKA,SAAU;GAAE,aAAa;GAAM,cAAc;GAAqB,CAAC;AAExE,MAAI;GACF,MAAM,sBAAsB,IAAI,aAC9B,KAAK,IACL,KAAK,QAAQ,oBACd;AACD,QAAK,cAAc,IAAI,qBAAqB,oBAAoB;GAChE,MAAM,SAAS,MAAM,oBAAoB,QAAQ,MAAM;AACvD,SAAKA,SAAU;IACb,qBACE,KAAK,MAAM,MAAM,sBAAsB,MAAM;IAC/C,YAAY;IACZ,cAAc,KAAK,MAAM,MAAM,eAAe;IAC/C,CAAC;AACF,QAAK,QAAQ,YAAY,QAAQ,OAAO,KAAK;AAC7C,UAAO;WACA,OAAO;AACd,SAAKA,SAAU;IACb,YAAY,KAAK,MAAM,MAAM,aAAa;IAC1C,aAAa,CAAC,GAAG,KAAK,MAAM,MAAM,aAAa,GAAG,MAAM;IACxD,kBAAkB,KAAK,MAAM,MAAM,mBAAmB,MAAM;IAC7D,CAAC;AACF,QAAK,QAAQ,UAAU,OAAgB,OAAO,KAAK;AACnD,OAAI,KAAK,QAAQ,aACf,OAAM;AAER;YACQ;AACR,QAAK,cAAc,OAAO,oBAAoB;AAC9C,SAAKA,SAAU;IACb,aAAa;IACb,aAAa,KAAK,MAAM,MAAM,cAAc;IAC7C,CAAC;AACF,QAAK,QAAQ,YAAY,OAAO,KAAK;;;CAuBzC,sBAA4B;AAC1B,MAAI,MAAKG,WAAY;AACnB,gBAAa,MAAKA,UAAW;AAC7B,SAAKA,YAAa;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AA4IxB,SAAgB,WACd,IACA,SACA;AAEA,QADgB,IAAI,aAAqB,IAAI,QAAQ,CACtC"}

Returns promises that can be awaited for batch results\n * - Built-in retry support via AsyncRetryer integration\n * - Abort support to cancel in-flight batch executions\n * - Cancel support to prevent pending batches from starting\n * - Comprehensive error handling with onError callbacks and throwOnError control\n * - Detailed execution tracking (success/error/settle counts)\n *\n * The sync Batcher is lighter weight and simpler when you don't need async features,\n * return values, or execution control.\n *\n * What is Batching?\n * Batching is a technique for grouping multiple operations together to be processed as a single unit.\n *\n * The AsyncBatcher provides a flexible way to implement async batching with configurable:\n * - Maximum batch size (number of items per batch)\n * - Time-based batching (process after X milliseconds)\n * - Custom batch processing logic via getShouldExecute\n * - Event callbacks for monitoring batch operations\n * - Error handling for failed batch operations\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error, the batch of items that failed, and batcher instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the AsyncBatcher instance\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async batcher\n * - Use `onSuccess` callback to react to successful batch execution and implement custom logic\n * - Use `onError` callback to react to batch execution errors and implement custom error handling\n * - Use `onSettled` callback to react to batch execution completion (success or error) and implement custom logic\n * - Use `onExecute` callback to react to batch execution and implement custom logic\n * - Use `onItemsChange` callback to react to items being added or removed from the batcher\n * - The state includes total items processed, success/error counts, and execution status\n * - State can be accessed via `asyncBatcher.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `asyncBatcher.state`\n *\n * @example\n * ```ts\n * const batcher = new AsyncBatcher<number>(\n *   async (items) => {\n *     const result = await processItems(items);\n *     console.log('Processing batch:', items);\n *     return result;\n *   },\n *   {\n *     maxSize: 5,\n *     wait: 2000,\n *     onSuccess: (result) => console.log('Batch succeeded:', result),\n *     onError: (error) => console.error('Batch failed:', error)\n *   }\n * );\n *\n * batcher.addItem(1);\n * batcher.addItem(2);\n * // After 2 seconds or when 5 items are added, whichever comes first,\n * // the batch will be processed and the result will be available\n * // batcher.execute() // manually trigger a batch\n * ```\n */\nexport class AsyncBatcher<TValue> {\n  readonly store: Store<Readonly<AsyncBatcherState<TValue>>> = new Store(\n    getDefaultAsyncBatcherState<TValue>(),\n  )\n  key: string | undefined\n  options: AsyncBatcherOptionsWithOptionalCallbacks<TValue>\n  asyncRetryers = new Map<\n    number,\n    AsyncRetryer<(items: Array<TValue>) => Promise<any>>\n  >()\n  #timeoutId: ReturnType<typeof setTimeout> | null = null\n\n  constructor(\n    public fn: (items: Array<TValue>) => Promise<any>,\n    initialOptions: AsyncBatcherOptions<TValue>,\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n      throwOnError: initialOptions.throwOnError ?? !initialOptions.onError,\n    }\n    this.#setState(this.options.initialState ?? {})\n\n    if (this.key) {\n      pacerEventClient.on('d-AsyncBatcher', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(\n          event.payload.store.state as Partial<AsyncBatcherState<TValue>>,\n        )\n        this.setOptions(\n          event.payload.options as Partial<AsyncBatcherOptions<TValue>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the async batcher options\n   */\n  setOptions = (newOptions: Partial<AsyncBatcherOptions<TValue>>): void => {\n    this.options = { ...this.options, ...newOptions }\n  }\n\n  #setState = (newState: Partial<AsyncBatcherState<TValue>>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const { isExecuting, isPending, items } = combinedState\n      const size = items.length\n      const isEmpty = size === 0\n      return {\n        ...combinedState,\n        isEmpty,\n        size,\n        status: isExecuting\n          ?

This is useful for handling frequent events like window resizing\n * or input changes where you only want to execute the handler after the events have stopped occurring.\n *\n * Unlike throttling which allows execution at regular intervals, debouncing prevents any execution until\n * the function stops being called for the specified delay period.\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and debouncer instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the underlying store\n *\n * State Management:\n * - The debouncer uses a reactive store for state management\n * - Use `initialState` to provide initial state values when creating the async debouncer\n * - The state includes canLeadingExecute, error count, execution status, and success/settle counts\n * - State can be accessed via the `store` property and its `state` getter\n * - The store is reactive and will notify subscribers of state changes\n *\n * @example\n * ```ts\n * const asyncDebouncer = new AsyncDebouncer(async (value: string) => {\n *   const results = await searchAPI(value);\n *   return results; // Return value is preserved\n * }, {\n *   wait: 500,\n *   onError: (error) => {\n *     console.error('Search failed:', error);\n *   }\n * });\n *\n * // Called on each keystroke but only executes after 500ms of no typing\n * // Returns the API response directly\n * const results = await asyncDebouncer.maybeExecute(inputElement.value);\n * ```\n */\nexport class AsyncDebouncer<TFn extends AnyAsyncFunction> {\n  readonly store: Store<Readonly<AsyncDebouncerState<TFn>>> = new Store<\n    AsyncDebouncerState<TFn>\n  >(getDefaultAsyncDebouncerState<TFn>())\n  key: string | undefined\n  options: AsyncDebouncerOptions<TFn>\n  asyncRetryers = new Map<number, AsyncRetryer<TFn>>()\n  #timeoutId: NodeJS.Timeout | null = null\n  #resolvePreviousPromise:\n    | ((value?: ReturnType<TFn> | undefined) => void)\n    | null = null\n\n  constructor(\n    public fn: TFn,\n    initialOptions: AsyncDebouncerOptions<TFn>,\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n      throwOnError: initialOptions.throwOnError ?? !initialOptions.onError,\n    }\n    this.#setState(this.options.initialState ?? {})\n\n    if (this.key) {\n      pacerEventClient.on('d-AsyncDebouncer', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(\n          event.payload.store.state as Partial<AsyncDebouncerState<TFn>>,\n        )\n        this.setOptions(\n          event.payload.options as Partial<AsyncDebouncerOptions<TFn>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the async debouncer options\n   */\n  setOptions = (newOptions: Partial<AsyncDebouncerOptions<TFn>>): void => {\n    this.options = { ...this.options, ...newOptions }\n\n    // Cancel pending execution if the debouncer is disabled\n    if (!this.#getEnabled()) {\n      this.cancel()\n    }\n  }\n\n  #setState = (newState: Partial<AsyncDebouncerState<TFn>>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const { isPending, isExecuting, settleCount } = combinedState\n      return {\n        ...combinedState,\n        status: !this.#getEnabled()\n          ?

Comprehensive error handling with onError callbacks and throwOnError control\n * - Detailed execution tracking (success/error/settle counts)\n *\n * The sync debounce function is lighter weight and simpler when you don't need async features,\n * return values, or execution control.\n *\n * What is Debouncing?\n * Debouncing ensures that a function is only executed after a specified delay has passed since its last invocation.\n * Each new invocation resets the delay timer. This is useful for handling frequent events like window resizing\n * or input changes where you only want to execute the handler after the events have stopped occurring.\n *\n * Configuration Options:\n * - `wait`: Delay in milliseconds to wait after the last call (required)\n * - `leading`: Execute on the leading edge of the timeout (default: false)\n * - `trailing`: Execute on the trailing edge of the timeout (default: true)\n * - `enabled`: Whether the debouncer is enabled (default: true)\n * - `asyncRetryerOptions`: Configure retry behavior for executions\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and debouncer instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - The error state can be checked using the underlying AsyncDebouncer instance\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async debouncer\n * - Use `onSuccess` callback to react to successful function execution and implement custom logic\n * - Use `onError` callback to react to function execution errors and implement custom error handling\n * - Use `onSettled` callback to react to function execution completion (success or error) and implement custom logic\n * - The state includes canLeadingExecute, error count, execution status, and success/settle counts\n * - State can be accessed via `asyncDebouncer.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `asyncDebouncer.state`\n *\n * @example\n * ```ts\n * const debounced = asyncDebounce(async (value: string) => {\n *   const result = await saveToAPI(value);\n *   return result; // Return value is preserved\n * }, {\n *   wait: 1000,\n *   onError: (error) => {\n *     console.error('API call failed:', error);\n *   },\n *   throwOnError: true // Will both log the error and throw it\n * });\n *\n * // Will only execute once, 1 second after the last call\n * // Returns the API response directly\n * const result = await debounced(\"third\");\n * ```\n */\nexport function asyncDebounce<TFn extends AnyAsyncFunction>(\n  fn: TFn,\n  initialOptions: AsyncDebouncerOptions<TFn>,\n) {\n  const asyncDebouncer = new AsyncDebouncer(fn, initialOptions)\n  return asyncDebouncer.maybeExecute\n}\n"],"mappings":";;;;;;;AAkDA,SAAS,gCAEqB;AAC5B,QAAO;EACL,mBAAmB;EACnB,YAAY;EACZ,aAAa;EACb,WAAW;EACX,UAAU;EACV,YAAY;EACZ,mBAAmB;EACnB,aAAa;EACb,QAAQ;EACR,cAAc;EACf;;;;;AA2EH,SAAgB,sBAKd,SAA6B;AAC7B,QAAO;;AAQT,MAAM,iBAA6D;CACjE,qBAAqB,EACnB,aAAa,GACd;CACD,SAAS;CACT,SAAS;CACT,UAAU;CACV,MAAM;CACP;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AAwDD,IAAa,iBAAb,MAA0D;CAOxD,aAAoC;CACpC,0BAEW;CAEX,YACE,AAAO,IACP,gBACA;EAFO;eAZmD,IAAIA,sBAE9D,+BAAoC,CAAC;uCAGvB,IAAI,KAAgC;qBAkCtC,eAA0D;AACtE,QAAK,UAAU;IAAE,GAAG,KAAK;IAAS,GAAG;IAAY;AAGjD,OAAI,CAAC,MAAKC,YAAa,CACrB,MAAK,QAAQ;;sBAuDF,OACb,GAAG,SACsC;AACzC,OAAI,CAAC,MAAKA,YAAa,CAAE,QAAO;AAChC,SAAKC,wBAAyB;AAC9B,SAAKC,SAAU;IACb,UAAU;IACV,mBAAmB,KAAK,MAAM,MAAM,oBAAoB;IACzD,CAAC;AAGF,OAAI,KAAK,QAAQ,WAAW,KAAK,MAAM,MAAM,mBAAmB;AAC9D,UAAKA,SAAU,EAAE,mBAAmB,OAAO,CAAC;AAC5C,UAAM,MAAKC,QAAS,GAAG,KAAK;AAC5B,WAAO,KAAK,MAAM,MAAM;;AAI1B,OAAI,KAAK,QAAQ,YAAY,MAAKH,YAAa,CAC7C,OAAKE,SAAU,EAAE,WAAW,MAAM,CAAC;AAGrC,UAAO,IAAI,SAAS,SAAS,WAAW;AACtC,UAAKE,yBAA0B;AAE/B,UAAKC,YAAa,WAAW,YAAY;AAEvC,SAAI,KAAK,QAAQ,YAAY,KAAK,MAAM,MAAM,SAC5C,KAAI;AACF,YAAM,MAAKF,QAAS,GAAG,KAAK,MAAM,MAAM,SAAS;cAC1C,OAAO;AACd,aAAO,MAAM;;AAKjB,WAAKD,SAAU,EAAE,mBAAmB,MAAM,CAAC;AAC3C,WAAKE,yBAA0B;AAC/B,aAAQ,KAAK,MAAM,MAAM,WAAW;OACnC,MAAKE,SAAU,CAAC;KACnB;;eA8CI,YAAkD;AACxD,OAAI,KAAK,MAAM,MAAM,aAAa,KAAK,MAAM,MAAM,UAAU;IAC3D,MAAM,EAAE,aAAa,KAAK,MAAM;AAChC,UAAKL,wBAAyB;AAC9B,WAAO,MAAM,MAAKE,QAAS,GAAG,SAAS;;;yBAmDzB,sBAAmD;GACnE,MAAM,QAAQ,qBAAqB,KAAK,MAAM,MAAM;AAEpD,UADgB,KAAK,cAAc,IAAI,MAAM,EAC7B,gBAAgB,IAAI;;qBAOlB;AAClB,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;AACxD,QAAK,cAAc,OAAO;AAC1B,SAAKD,SAAU,EACb,aAAa,OACd,CAAC;;sBAOiB;AACnB,SAAKD,wBAAyB;AAC9B,SAAKC,SAAU,EAAE,mBAAmB,MAAM,CAAC;;qBAMzB;AAClB,SAAKA,SAAU,+BAAoC,CAAC;AACpD,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;;AAjQxD,OAAK,MAAM,eAAe;AAC1B,OAAK,UAAU;GACb,GAAG;GACH,GAAG;GACH,cAAc,eAAe,gBAAgB,CAAC,eAAe;GAC9D;AACD,QAAKA,SAAU,KAAK,QAAQ,gBAAgB,EAAE,CAAC;AAE/C,MAAI,KAAK,IACP,uCAAiB,GAAG,qBAAqB,UAAU;AACjD,OAAI,MAAM,QAAQ,QAAQ,KAAK,IAAK;AACpC,SAAKA,SACH,MAAM,QAAQ,MAAM,MACrB;AACD,QAAK,WACH,MAAM,QAAQ,QACf;IACD;;CAgBN,aAAa,aAAsD;AACjE,OAAK,MAAM,UAAU,UAAU;GAC7B,MAAM,gBAAgB;IACpB,GAAG;IACH,GAAG;IACJ;GACD,MAAM,EAAE,WAAW,aAAa,gBAAgB;AAChD,UAAO;IACL,GAAG;IACH,QAAQ,CAAC,MAAKF,YAAa,GACvB,aACA,YACE,YACA,cACE,cACA,cAAc,IACZ,YACA;IACX;IACD;AACF,kCAAW,kBAAkB,KAAK;;;;;CAMpC,oBAA6B;AAC3B,SAAO,CAAC,CAACO,mCAAqB,KAAK,QAAQ,SAAS,KAAK;;;;;CAM3D,iBAAyB;AACvB,SAAOA,mCAAqB,KAAK,QAAQ,MAAM,KAAK;;CA4DtD,WAAW,OACT,GAAG,SACsC;AACzC,MAAI,CAAC,MAAKP,YAAa,CAAE,QAAO;EAChC,MAAM,2BAA2B,KAAK,MAAM,MAAM,oBAAoB;AAEtE,MAAI;AACF,SAAKE,SAAU,EAAE,aAAa,MAAM,CAAC;GACrC,MAAM,sBAAsB,IAAIM,mCAAa,KAAK,IAAI;IACpD,GAAG,KAAK,QAAQ;IAChB,KAAK,GAAG,KAAK,IAAI,WAAW;IAC7B,CAAC;AACF,QAAK,cAAc,IAAI,0BAA0B,oBAAoB;GACrE,MAAM,SAAS,MAAM,oBAAoB,QAAQ,GAAG,KAAK;AACzD,SAAKN,SAAU;IACb,YAAY;IACZ,cAAc,KAAK,MAAM,MAAM,eAAe;IAC/C,CAAC;AACF,QAAK,QAAQ,YAAY,QAA2B,MAAM,KAAK;WACxD,OAAO;AACd,SAAKA,SAAU,EACb,YAAY,KAAK,MAAM,MAAM,aAAa,GAC3C,CAAC;AACF,QAAK,QAAQ,UAAU,OAAgB,MAAM,KAAK;AAClD,OAAI,KAAK,QAAQ,aACf,OAAM;YAEA;AACR,QAAK,cAAc,OAAO,yBAAyB;AACnD,SAAKA,SAAU;IACb,aAAa;IACb,WAAW;IACX,UAAU;IACV,aAAa,KAAK,MAAM,MAAM,cAAc;IAC7C,CAAC;AACF,QAAK,QAAQ,YAAY,MAAM,KAAK;;AAEtC,SAAO,KAAK,MAAM,MAAM;;CAe1B,wCAA8C;AAC5C,MAAI,MAAKE,wBAAyB;AAChC,SAAKA,uBAAwB,KAAK,MAAM,MAAM,WAAW;AACzD,SAAKA,yBAA0B;;;CAInC,sBAA4B;AAC1B,MAAI,MAAKC,WAAY;AACnB,gBAAa,MAAKA,UAAW;AAC7B,SAAKA,YAAa;;;;;;CAOtB,gCAAsC;AACpC,QAAKI,cAAe;AACpB,QAAKC,gCAAiC;AACtC,QAAKR,SAAU;GACb,WAAW;GACX,UAAU;GACX,CAAC;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AA2HN,SAAgB,cACd,IACA,gBACA;AAEA,QADuB,IAAI,eAAe,IAAI,eAAe,CACvC"}

Returns promises that can be awaited for debounced function results\n * - Built-in retry support via AsyncRetryer integration\n * - Abort support to cancel in-flight executions\n * - Cancel support to prevent pending executions from starting\n * - Comprehensive error handling with onError callbacks and throwOnError control\n * - Detailed execution tracking (success/error/settle counts)\n *\n * The sync debounce function is lighter weight and simpler when you don't need async features,\n * return values, or execution control.\n *\n * What is Debouncing?\n * Debouncing ensures that a function is only executed after a specified delay has passed since its last invocation.\n * Each new invocation resets the delay timer. This is useful for handling frequent events like window resizing\n * or input changes where you only want to execute the handler after the events have stopped occurring.\n *\n * Configuration Options:\n * - `wait`: Delay in milliseconds to wait after the last call (required)\n * - `leading`: Execute on the leading edge of the timeout (default: false)\n * - `trailing`: Execute on the trailing edge of the timeout (default: true)\n * - `enabled`: Whether the debouncer is enabled (default: true)\n * - `asyncRetryerOptions`: Configure retry behavior for executions\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and debouncer instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - The error state can be checked using the underlying AsyncDebouncer instance\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async debouncer\n * - Use `onSuccess` callback to react to successful function execution and implement custom logic\n * - Use `onError` callback to react to function execution errors and implement custom error handling\n * - Use `onSettled` callback to react to function execution completion (success or error) and implement custom logic\n * - The state includes canLeadingExecute, error count, execution status, and success/settle counts\n * - State can be accessed via `asyncDebouncer.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `asyncDebouncer.state`\n *\n * @example\n * ```ts\n * const debounced = asyncDebounce(async (value: string) => {\n *   const result = await saveToAPI(value);\n *   return result; // Return value is preserved\n * }, {\n *   wait: 1000,\n *   onError: (error) => {\n *     console.error('API call failed:', error);\n *   },\n *   throwOnError: true // Will both log the error and throw it\n * });\n *\n * // Will only execute once, 1 second after the last call\n * // Returns the API response directly\n * const result = await debounced(\"third\");\n * ```\n */\nexport function asyncDebounce<TFn extends AnyAsyncFunction>(\n  fn: TFn,\n  initialOptions: AsyncDebouncerOptions<TFn>,\n) {\n  const asyncDebouncer = new AsyncDebouncer(fn, initialOptions)\n  return asyncDebouncer.maybeExecute\n}\n"],"mappings":";;;;;;;AAkDA,SAAS,gCAEqB;AAC5B,QAAO;EACL,mBAAmB;EACnB,YAAY;EACZ,aAAa;EACb,WAAW;EACX,UAAU;EACV,YAAY;EACZ,mBAAmB;EACnB,aAAa;EACb,QAAQ;EACR,cAAc;EACf;;;;;AA2EH,SAAgB,sBAKd,SAA6B;AAC7B,QAAO;;AAQT,MAAM,iBAA6D;CACjE,qBAAqB,EACnB,aAAa,GACd;CACD,SAAS;CACT,SAAS;CACT,UAAU;CACV,MAAM;CACP;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AAwDD,IAAa,iBAAb,MAA0D;CAOxD,aAAmD;CACnD,0BAEW;CAEX,YACE,AAAO,IACP,gBACA;EAFO;eAZmD,IAAIA,sBAE9D,+BAAoC,CAAC;uCAGvB,IAAI,KAAgC;qBAkCtC,eAA0D;AACtE,QAAK,UAAU;IAAE,GAAG,KAAK;IAAS,GAAG;IAAY;AAGjD,OAAI,CAAC,MAAKC,YAAa,CACrB,MAAK,QAAQ;;sBAuDF,OACb,GAAG,SACsC;AACzC,OAAI,CAAC,MAAKA,YAAa,CAAE,QAAO;AAChC,SAAKC,wBAAyB;AAC9B,SAAKC,SAAU;IACb,UAAU;IACV,mBAAmB,KAAK,MAAM,MAAM,oBAAoB;IACzD,CAAC;AAGF,OAAI,KAAK,QAAQ,WAAW,KAAK,MAAM,MAAM,mBAAmB;AAC9D,UAAKA,SAAU,EAAE,mBAAmB,OAAO,CAAC;AAC5C,UAAM,MAAKC,QAAS,GAAG,KAAK;AAC5B,WAAO,KAAK,MAAM,MAAM;;AAI1B,OAAI,KAAK,QAAQ,YAAY,MAAKH,YAAa,CAC7C,OAAKE,SAAU,EAAE,WAAW,MAAM,CAAC;AAGrC,UAAO,IAAI,SAAS,SAAS,WAAW;AACtC,UAAKE,yBAA0B;AAE/B,UAAKC,YAAa,WAAW,YAAY;AAEvC,SAAI,KAAK,QAAQ,YAAY,KAAK,MAAM,MAAM,SAC5C,KAAI;AACF,YAAM,MAAKF,QAAS,GAAG,KAAK,MAAM,MAAM,SAAS;cAC1C,OAAO;AACd,aAAO,MAAM;;AAKjB,WAAKD,SAAU,EAAE,mBAAmB,MAAM,CAAC;AAC3C,WAAKE,yBAA0B;AAC/B,aAAQ,KAAK,MAAM,MAAM,WAAW;OACnC,MAAKE,SAAU,CAAC;KACnB;;eA8CI,YAAkD;AACxD,OAAI,KAAK,MAAM,MAAM,aAAa,KAAK,MAAM,MAAM,UAAU;IAC3D,MAAM,EAAE,aAAa,KAAK,MAAM;AAChC,UAAKL,wBAAyB;AAC9B,WAAO,MAAM,MAAKE,QAAS,GAAG,SAAS;;;yBAmDzB,sBAAmD;GACnE,MAAM,QAAQ,qBAAqB,KAAK,MAAM,MAAM;AAEpD,UADgB,KAAK,cAAc,IAAI,MAAM,EAC7B,gBAAgB,IAAI;;qBAOlB;AAClB,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;AACxD,QAAK,cAAc,OAAO;AAC1B,SAAKD,SAAU,EACb,aAAa,OACd,CAAC;;sBAOiB;AACnB,SAAKD,wBAAyB;AAC9B,SAAKC,SAAU,EAAE,mBAAmB,MAAM,CAAC;;qBAMzB;AAClB,SAAKA,SAAU,+BAAoC,CAAC;AACpD,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;;AAjQxD,OAAK,MAAM,eAAe;AAC1B,OAAK,UAAU;GACb,GAAG;GACH,GAAG;GACH,cAAc,eAAe,gBAAgB,CAAC,eAAe;GAC9D;AACD,QAAKA,SAAU,KAAK,QAAQ,gBAAgB,EAAE,CAAC;AAE/C,MAAI,KAAK,IACP,uCAAiB,GAAG,qBAAqB,UAAU;AACjD,OAAI,MAAM,QAAQ,QAAQ,KAAK,IAAK;AACpC,SAAKA,SACH,MAAM,QAAQ,MAAM,MACrB;AACD,QAAK,WACH,MAAM,QAAQ,QACf;IACD;;CAgBN,aAAa,aAAsD;AACjE,OAAK,MAAM,UAAU,UAAU;GAC7B,MAAM,gBAAgB;IACpB,GAAG;IACH,GAAG;IACJ;GACD,MAAM,EAAE,WAAW,aAAa,gBAAgB;AAChD,UAAO;IACL,GAAG;IACH,QAAQ,CAAC,MAAKF,YAAa,GACvB,aACA,YACE,YACA,cACE,cACA,cAAc,IACZ,YACA;IACX;IACD;AACF,kCAAW,kBAAkB,KAAK;;;;;CAMpC,oBAA6B;AAC3B,SAAO,CAAC,CAACO,mCAAqB,KAAK,QAAQ,SAAS,KAAK;;;;;CAM3D,iBAAyB;AACvB,SAAOA,mCAAqB,KAAK,QAAQ,MAAM,KAAK;;CA4DtD,WAAW,OACT,GAAG,SACsC;AACzC,MAAI,CAAC,MAAKP,YAAa,CAAE,QAAO;EAChC,MAAM,2BAA2B,KAAK,MAAM,MAAM,oBAAoB;AAEtE,MAAI;AACF,SAAKE,SAAU,EAAE,aAAa,MAAM,CAAC;GACrC,MAAM,sBAAsB,IAAIM,mCAAa,KAAK,IAAI;IACpD,GAAG,KAAK,QAAQ;IAChB,KAAK,GAAG,KAAK,IAAI,WAAW;IAC7B,CAAC;AACF,QAAK,cAAc,IAAI,0BAA0B,oBAAoB;GACrE,MAAM,SAAS,MAAM,oBAAoB,QAAQ,GAAG,KAAK;AACzD,SAAKN,SAAU;IACb,YAAY;IACZ,cAAc,KAAK,MAAM,MAAM,eAAe;IAC/C,CAAC;AACF,QAAK,QAAQ,YAAY,QAA2B,MAAM,KAAK;WACxD,OAAO;AACd,SAAKA,SAAU,EACb,YAAY,KAAK,MAAM,MAAM,aAAa,GAC3C,CAAC;AACF,QAAK,QAAQ,UAAU,OAAgB,MAAM,KAAK;AAClD,OAAI,KAAK,QAAQ,aACf,OAAM;YAEA;AACR,QAAK,cAAc,OAAO,yBAAyB;AACnD,SAAKA,SAAU;IACb,aAAa;IACb,WAAW;IACX,UAAU;IACV,aAAa,KAAK,MAAM,MAAM,cAAc;IAC7C,CAAC;AACF,QAAK,QAAQ,YAAY,MAAM,KAAK;;AAEtC,SAAO,KAAK,MAAM,MAAM;;CAe1B,wCAA8C;AAC5C,MAAI,MAAKE,wBAAyB;AAChC,SAAKA,uBAAwB,KAAK,MAAM,MAAM,WAAW;AACzD,SAAKA,yBAA0B;;;CAInC,sBAA4B;AAC1B,MAAI,MAAKC,WAAY;AACnB,gBAAa,MAAKA,UAAW;AAC7B,SAAKA,YAAa;;;;;;CAOtB,gCAAsC;AACpC,QAAKI,cAAe;AACpB,QAAKC,gCAAiC;AACtC,QAAKR,SAAU;GACb,WAAW;GACX,UAAU;GACX,CAAC;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AA2HN,SAAgB,cACd,IACA,gBACA;AAEA,QADuB,IAAI,eAAe,IAAI,eAAe,CACvC"}

// Return value is preserved\n * }, {\n *   wait: 1000,\n *   onError: (error) => {\n *     console.error('API call failed:', error);\n *   },\n *   throwOnError: true // Will both log the error and throw it\n * });\n *\n * // Will only execute once, 1 second after the last call\n * // Returns the API response directly\n * const result = await debounced(\"third\");\n * ```\n */\nexport function asyncDebounce<TFn extends AnyAsyncFunction>(\n  fn: TFn,\n  initialOptions: AsyncDebouncerOptions<TFn>,\n) {\n  const asyncDebouncer = new AsyncDebouncer(fn, initialOptions)\n  return asyncDebouncer.maybeExecute\n}\n"],"mappings":";;;;;;AAkDA,SAAS,gCAEqB;AAC5B,QAAO;EACL,mBAAmB;EACnB,YAAY;EACZ,aAAa;EACb,WAAW;EACX,UAAU;EACV,YAAY;EACZ,mBAAmB;EACnB,aAAa;EACb,QAAQ;EACR,cAAc;EACf;;;;;AA2EH,SAAgB,sBAKd,SAA6B;AAC7B,QAAO;;AAQT,MAAM,iBAA6D;CACjE,qBAAqB,EACnB,aAAa,GACd;CACD,SAAS;CACT,SAAS;CACT,UAAU;CACV,MAAM;CACP;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AAwDD,IAAa,iBAAb,MAA0D;CAOxD,aAAoC;CACpC,0BAEW;CAEX,YACE,AAAO,IACP,gBACA;EAFO;eAZmD,IAAI,MAE9D,+BAAoC,CAAC;uCAGvB,IAAI,KAAgC;qBAkCtC,eAA0D;AACtE,QAAK,UAAU;IAAE,GAAG,KAAK;IAAS,GAAG;IAAY;AAGjD,OAAI,CAAC,MAAKA,YAAa,CACrB,MAAK,QAAQ;;sBAuDF,OACb,GAAG,SACsC;AACzC,OAAI,CAAC,MAAKA,YAAa,CAAE,QAAO;AAChC,SAAKC,wBAAyB;AAC9B,SAAKC,SAAU;IACb,UAAU;IACV,mBAAmB,KAAK,MAAM,MAAM,oBAAoB;IACzD,CAAC;AAGF,OAAI,KAAK,QAAQ,WAAW,KAAK,MAAM,MAAM,mBAAmB;AAC9D,UAAKA,SAAU,EAAE,mBAAmB,OAAO,CAAC;AAC5C,UAAM,MAAKC,QAAS,GAAG,KAAK;AAC5B,WAAO,KAAK,MAAM,MAAM;;AAI1B,OAAI,KAAK,QAAQ,YAAY,MAAKH,YAAa,CAC7C,OAAKE,SAAU,EAAE,WAAW,MAAM,CAAC;AAGrC,UAAO,IAAI,SAAS,SAAS,WAAW;AACtC,UAAKE,yBAA0B;AAE/B,UAAKC,YAAa,WAAW,YAAY;AAEvC,SAAI,KAAK,QAAQ,YAAY,KAAK,MAAM,MAAM,SAC5C,KAAI;AACF,YAAM,MAAKF,QAAS,GAAG,KAAK,MAAM,MAAM,SAAS;cAC1C,OAAO;AACd,aAAO,MAAM;;AAKjB,WAAKD,SAAU,EAAE,mBAAmB,MAAM,CAAC;AAC3C,WAAKE,yBAA0B;AAC/B,aAAQ,KAAK,MAAM,MAAM,WAAW;OACnC,MAAKE,SAAU,CAAC;KACnB;;eA8CI,YAAkD;AACxD,OAAI,KAAK,MAAM,MAAM,aAAa,KAAK,MAAM,MAAM,UAAU;IAC3D,MAAM,EAAE,aAAa,KAAK,MAAM;AAChC,UAAKL,wBAAyB;AAC9B,WAAO,MAAM,MAAKE,QAAS,GAAG,SAAS;;;yBAmDzB,sBAAmD;GACnE,MAAM,QAAQ,qBAAqB,KAAK,MAAM,MAAM;AAEpD,UADgB,KAAK,cAAc,IAAI,MAAM,EAC7B,gBAAgB,IAAI;;qBAOlB;AAClB,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;AACxD,QAAK,cAAc,OAAO;AAC1B,SAAKD,SAAU,EACb,aAAa,OACd,CAAC;;sBAOiB;AACnB,SAAKD,wBAAyB;AAC9B,SAAKC,SAAU,EAAE,mBAAmB,MAAM,CAAC;;qBAMzB;AAClB,SAAKA,SAAU,+BAAoC,CAAC;AACpD,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;;AAjQxD,OAAK,MAAM,eAAe;AAC1B,OAAK,UAAU;GACb,GAAG;GACH,GAAG;GACH,cAAc,eAAe,gBAAgB,CAAC,eAAe;GAC9D;AACD,QAAKA,SAAU,KAAK,QAAQ,gBAAgB,EAAE,CAAC;AAE/C,MAAI,KAAK,IACP,kBAAiB,GAAG,qBAAqB,UAAU;AACjD,OAAI,MAAM,QAAQ,QAAQ,KAAK,IAAK;AACpC,SAAKA,SACH,MAAM,QAAQ,MAAM,MACrB;AACD,QAAK,WACH,MAAM,QAAQ,QACf;IACD;;CAgBN,aAAa,aAAsD;AACjE,OAAK,MAAM,UAAU,UAAU;GAC7B,MAAM,gBAAgB;IACpB,GAAG;IACH,GAAG;IACJ;GACD,MAAM,EAAE,WAAW,aAAa,gBAAgB;AAChD,UAAO;IACL,GAAG;IACH,QAAQ,CAAC,MAAKF,YAAa,GACvB,aACA,YACE,YACA,cACE,cACA,cAAc,IACZ,YACA;IACX;IACD;AACF,aAAW,kBAAkB,KAAK;;;;;CAMpC,oBAA6B;AAC3B,SAAO,CAAC,CAAC,qBAAqB,KAAK,QAAQ,SAAS,KAAK;;;;;CAM3D,iBAAyB;AACvB,SAAO,qBAAqB,KAAK,QAAQ,MAAM,KAAK;;CA4DtD,WAAW,OACT,GAAG,SACsC;AACzC,MAAI,CAAC,MAAKA,YAAa,CAAE,QAAO;EAChC,MAAM,2BAA2B,KAAK,MAAM,MAAM,oBAAoB;AAEtE,MAAI;AACF,SAAKE,SAAU,EAAE,aAAa,MAAM,CAAC;GACrC,MAAM,sBAAsB,IAAI,aAAa,KAAK,IAAI;IACpD,GAAG,KAAK,QAAQ;IAChB,KAAK,GAAG,KAAK,IAAI,WAAW;IAC7B,CAAC;AACF,QAAK,cAAc,IAAI,0BAA0B,oBAAoB;GACrE,MAAM,SAAS,MAAM,oBAAoB,QAAQ,GAAG,KAAK;AACzD,SAAKA,SAAU;IACb,YAAY;IACZ,cAAc,KAAK,MAAM,MAAM,eAAe;IAC/C,CAAC;AACF,QAAK,QAAQ,YAAY,QAA2B,MAAM,KAAK;WACxD,OAAO;AACd,SAAKA,SAAU,EACb,YAAY,KAAK,MAAM,MAAM,aAAa,GAC3C,CAAC;AACF,QAAK,QAAQ,UAAU,OAAgB,MAAM,KAAK;AAClD,OAAI,KAAK,QAAQ,aACf,OAAM;YAEA;AACR,QAAK,cAAc,OAAO,yBAAyB;AACnD,SAAKA,SAAU;IACb,aAAa;IACb,WAAW;IACX,UAAU;IACV,aAAa,KAAK,MAAM,MAAM,cAAc;IAC7C,CAAC;AACF,QAAK,QAAQ,YAAY,MAAM,KAAK;;AAEtC,SAAO,KAAK,MAAM,MAAM;;CAe1B,wCAA8C;AAC5C,MAAI,MAAKE,wBAAyB;AAChC,SAAKA,uBAAwB,KAAK,MAAM,MAAM,WAAW;AACzD,SAAKA,yBAA0B;;;CAInC,sBAA4B;AAC1B,MAAI,MAAKC,WAAY;AACnB,gBAAa,MAAKA,UAAW;AAC7B,SAAKA,YAAa;;;;;;CAOtB,gCAAsC;AACpC,QAAKE,cAAe;AACpB,QAAKC,gCAAiC;AACtC,QAAKN,SAAU;GACb,WAAW;GACX,UAAU;GACX,CAAC;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AA2HN,SAAgB,cACd,IACA,gBACA;AAEA,QADuB,IAAI,eAAe,IAAI,eAAe,CACvC"}

This is useful for handling frequent events like window resizing\n * or input changes where you only want to execute the handler after the events have stopped occurring.\n *\n * Configuration Options:\n * - `wait`: Delay in milliseconds to wait after the last call (required)\n * - `leading`: Execute on the leading edge of the timeout (default: false)\n * - `trailing`: Execute on the trailing edge of the timeout (default: true)\n * - `enabled`: Whether the debouncer is enabled (default: true)\n * - `asyncRetryerOptions`: Configure retry behavior for executions\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and debouncer instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - The error state can be checked using the underlying AsyncDebouncer instance\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async debouncer\n * - Use `onSuccess` callback to react to successful function execution and implement custom logic\n * - Use `onError` callback to react to function execution errors and implement custom error handling\n * - Use `onSettled` callback to react to function execution completion (success or error) and implement custom logic\n * - The state includes canLeadingExecute, error count, execution status, and success/settle counts\n * - State can be accessed via `asyncDebouncer.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `asyncDebouncer.state`\n *\n * @example\n * ```ts\n * const debounced = asyncDebounce(async (value: string) => {\n *   const result = await saveToAPI(value);\n *   return result; // Return value is preserved\n * }, {\n *   wait: 1000,\n *   onError: (error) => {\n *     console.error('API call failed:', error);\n *   },\n *   throwOnError: true // Will both log the error and throw it\n * });\n *\n * // Will only execute once, 1 second after the last call\n * // Returns the API response directly\n * const result = await debounced(\"third\");\n * ```\n */\nexport function asyncDebounce<TFn extends AnyAsyncFunction>(\n  fn: TFn,\n  initialOptions: AsyncDebouncerOptions<TFn>,\n) {\n  const asyncDebouncer = new AsyncDebouncer(fn, initialOptions)\n  return asyncDebouncer.maybeExecute\n}\n"],"mappings":";;;;;;AAkDA,SAAS,gCAEqB;AAC5B,QAAO;EACL,mBAAmB;EACnB,YAAY;EACZ,aAAa;EACb,WAAW;EACX,UAAU;EACV,YAAY;EACZ,mBAAmB;EACnB,aAAa;EACb,QAAQ;EACR,cAAc;EACf;;;;;AA2EH,SAAgB,sBAKd,SAA6B;AAC7B,QAAO;;AAQT,MAAM,iBAA6D;CACjE,qBAAqB,EACnB,aAAa,GACd;CACD,SAAS;CACT,SAAS;CACT,UAAU;CACV,MAAM;CACP;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AAwDD,IAAa,iBAAb,MAA0D;CAOxD,aAAmD;CACnD,0BAEW;CAEX,YACE,AAAO,IACP,gBACA;EAFO;eAZmD,IAAI,MAE9D,+BAAoC,CAAC;uCAGvB,IAAI,KAAgC;qBAkCtC,eAA0D;AACtE,QAAK,UAAU;IAAE,GAAG,KAAK;IAAS,GAAG;IAAY;AAGjD,OAAI,CAAC,MAAKA,YAAa,CACrB,MAAK,QAAQ;;sBAuDF,OACb,GAAG,SACsC;AACzC,OAAI,CAAC,MAAKA,YAAa,CAAE,QAAO;AAChC,SAAKC,wBAAyB;AAC9B,SAAKC,SAAU;IACb,UAAU;IACV,mBAAmB,KAAK,MAAM,MAAM,oBAAoB;IACzD,CAAC;AAGF,OAAI,KAAK,QAAQ,WAAW,KAAK,MAAM,MAAM,mBAAmB;AAC9D,UAAKA,SAAU,EAAE,mBAAmB,OAAO,CAAC;AAC5C,UAAM,MAAKC,QAAS,GAAG,KAAK;AAC5B,WAAO,KAAK,MAAM,MAAM;;AAI1B,OAAI,KAAK,QAAQ,YAAY,MAAKH,YAAa,CAC7C,OAAKE,SAAU,EAAE,WAAW,MAAM,CAAC;AAGrC,UAAO,IAAI,SAAS,SAAS,WAAW;AACtC,UAAKE,yBAA0B;AAE/B,UAAKC,YAAa,WAAW,YAAY;AAEvC,SAAI,KAAK,QAAQ,YAAY,KAAK,MAAM,MAAM,SAC5C,KAAI;AACF,YAAM,MAAKF,QAAS,GAAG,KAAK,MAAM,MAAM,SAAS;cAC1C,OAAO;AACd,aAAO,MAAM;;AAKjB,WAAKD,SAAU,EAAE,mBAAmB,MAAM,CAAC;AAC3C,WAAKE,yBAA0B;AAC/B,aAAQ,KAAK,MAAM,MAAM,WAAW;OACnC,MAAKE,SAAU,CAAC;KACnB;;eA8CI,YAAkD;AACxD,OAAI,KAAK,MAAM,MAAM,aAAa,KAAK,MAAM,MAAM,UAAU;IAC3D,MAAM,EAAE,aAAa,KAAK,MAAM;AAChC,UAAKL,wBAAyB;AAC9B,WAAO,MAAM,MAAKE,QAAS,GAAG,SAAS;;;yBAmDzB,sBAAmD;GACnE,MAAM,QAAQ,qBAAqB,KAAK,MAAM,MAAM;AAEpD,UADgB,KAAK,cAAc,IAAI,MAAM,EAC7B,gBAAgB,IAAI;;qBAOlB;AAClB,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;AACxD,QAAK,cAAc,OAAO;AAC1B,SAAKD,SAAU,EACb,aAAa,OACd,CAAC;;sBAOiB;AACnB,SAAKD,wBAAyB;AAC9B,SAAKC,SAAU,EAAE,mBAAmB,MAAM,CAAC;;qBAMzB;AAClB,SAAKA,SAAU,+BAAoC,CAAC;AACpD,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;;AAjQxD,OAAK,MAAM,eAAe;AAC1B,OAAK,UAAU;GACb,GAAG;GACH,GAAG;GACH,cAAc,eAAe,gBAAgB,CAAC,eAAe;GAC9D;AACD,QAAKA,SAAU,KAAK,QAAQ,gBAAgB,EAAE,CAAC;AAE/C,MAAI,KAAK,IACP,kBAAiB,GAAG,qBAAqB,UAAU;AACjD,OAAI,MAAM,QAAQ,QAAQ,KAAK,IAAK;AACpC,SAAKA,SACH,MAAM,QAAQ,MAAM,MACrB;AACD,QAAK,WACH,MAAM,QAAQ,QACf;IACD;;CAgBN,aAAa,aAAsD;AACjE,OAAK,MAAM,UAAU,UAAU;GAC7B,MAAM,gBAAgB;IACpB,GAAG;IACH,GAAG;IACJ;GACD,MAAM,EAAE,WAAW,aAAa,gBAAgB;AAChD,UAAO;IACL,GAAG;IACH,QAAQ,CAAC,MAAKF,YAAa,GACvB,aACA,YACE,YACA,cACE,cACA,cAAc,IACZ,YACA;IACX;IACD;AACF,aAAW,kBAAkB,KAAK;;;;;CAMpC,oBAA6B;AAC3B,SAAO,CAAC,CAAC,qBAAqB,KAAK,QAAQ,SAAS,KAAK;;;;;CAM3D,iBAAyB;AACvB,SAAO,qBAAqB,KAAK,QAAQ,MAAM,KAAK;;CA4DtD,WAAW,OACT,GAAG,SACsC;AACzC,MAAI,CAAC,MAAKA,YAAa,CAAE,QAAO;EAChC,MAAM,2BAA2B,KAAK,MAAM,MAAM,oBAAoB;AAEtE,MAAI;AACF,SAAKE,SAAU,EAAE,aAAa,MAAM,CAAC;GACrC,MAAM,sBAAsB,IAAI,aAAa,KAAK,IAAI;IACpD,GAAG,KAAK,QAAQ;IAChB,KAAK,GAAG,KAAK,IAAI,WAAW;IAC7B,CAAC;AACF,QAAK,cAAc,IAAI,0BAA0B,oBAAoB;GACrE,MAAM,SAAS,MAAM,oBAAoB,QAAQ,GAAG,KAAK;AACzD,SAAKA,SAAU;IACb,YAAY;IACZ,cAAc,KAAK,MAAM,MAAM,eAAe;IAC/C,CAAC;AACF,QAAK,QAAQ,YAAY,QAA2B,MAAM,KAAK;WACxD,OAAO;AACd,SAAKA,SAAU,EACb,YAAY,KAAK,MAAM,MAAM,aAAa,GAC3C,CAAC;AACF,QAAK,QAAQ,UAAU,OAAgB,MAAM,KAAK;AAClD,OAAI,KAAK,QAAQ,aACf,OAAM;YAEA;AACR,QAAK,cAAc,OAAO,yBAAyB;AACnD,SAAKA,SAAU;IACb,aAAa;IACb,WAAW;IACX,UAAU;IACV,aAAa,KAAK,MAAM,MAAM,cAAc;IAC7C,CAAC;AACF,QAAK,QAAQ,YAAY,MAAM,KAAK;;AAEtC,SAAO,KAAK,MAAM,MAAM;;CAe1B,wCAA8C;AAC5C,MAAI,MAAKE,wBAAyB;AAChC,SAAKA,uBAAwB,KAAK,MAAM,MAAM,WAAW;AACzD,SAAKA,yBAA0B;;;CAInC,sBAA4B;AAC1B,MAAI,MAAKC,WAAY;AACnB,gBAAa,MAAKA,UAAW;AAC7B,SAAKA,YAAa;;;;;;CAOtB,gCAAsC;AACpC,QAAKE,cAAe;AACpB,QAAKC,gCAAiC;AACtC,QAAKN,SAAU;GACb,WAAW;GACX,UAAU;GACX,CAAC;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AA2HN,SAAgB,cACd,IACA,gBACA;AAEA,QADuB,IAAI,eAAe,IAAI,eAAe,CACvC"}

When a task completes,\n * the next pending task is processed if the concurrency limit allows.\n *\n * Key Features:\n * - Priority queue support via the getPriority option\n * - Configurable concurrency limit\n * - Callbacks for task success, error, completion, and queue state changes\n * - FIFO (First In First Out) or LIFO (Last In First Out) queue behavior\n * - Pause and resume processing\n * - Item expiration to remove stale items from the queue\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and queuer instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together; the handler will be called before any error is thrown\n * - The error state can be checked using the AsyncQueuer instance\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async queuer\n * - Use `onSuccess` callback to react to successful task execution and implement custom logic\n * - Use `onError` callback to react to task execution errors and implement custom error handling\n * - Use `onSettled` callback to react to task execution completion (success or error) and implement custom logic\n * - Use `onItemsChange` callback to react to items being added or removed from the queue\n * - Use `onExpire` callback to react to items expiring and implement custom logic\n * - Use `onReject` callback to react to items being rejected when the queue is full\n * - The state includes error count, expiration count, rejection count, running status, and success/settle counts\n * - State can be accessed via `asyncQueuer.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `asyncQueuer.state`\n *\n * Example usage:\n * ```ts\n * const asyncQueuer = new AsyncQueuer<string>(async (item) => {\n *   // process item\n *   return item.toUpperCase();\n * }, {\n *   concurrency: 2,\n *   onSuccess: (result) => {\n *     console.log(result);\n *   }\n * });\n *\n * asyncQueuer.addItem('hello');\n * asyncQueuer.start();\n * ```\n */\nexport class AsyncQueuer<TValue> {\n  readonly store: Store<Readonly<AsyncQueuerState<TValue>>> = new Store<\n    AsyncQueuerState<TValue>\n  >(getDefaultAsyncQueuerState<TValue>())\n  key: string | undefined\n  options: AsyncQueuerOptions<TValue>\n  asyncRetryers = new Map<\n    number,\n    AsyncRetryer<(item: TValue) => Promise<any>>\n  >()\n  #timeoutIds: Set<NodeJS.Timeout> = new Set()\n\n  constructor(\n    public fn: (item: TValue) => Promise<any>,\n    initialOptions: AsyncQueuerOptions<TValue> = {},\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n      throwOnError: initialOptions.throwOnError ?? !initialOptions.onError,\n    }\n    const isInitiallyRunning =\n      this.options.initialState?.isRunning ?? this.options.started ?? true\n    this.#setState({\n      ...this.options.initialState,\n      isRunning: isInitiallyRunning,\n    })\n\n    if (this.options.initialState?.items) {\n      if (this.store.state.isRunning) {\n        this.#tick()\n      }\n    } else {\n      for (let i = 0; i < (this.options.initialItems?.length ?? 0); i++) {\n        const item = this.options.initialItems![i]!\n        const isLast = i === (this.options.initialItems?.length ?? 0) - 1\n        this.addItem(item, this.options.addItemsTo ??

Returns promises that can be awaited for task results\n * - Built-in retry support via AsyncRetryer integration for each queued task\n * - Abort support to cancel in-flight task executions\n * - Comprehensive error handling with onError callbacks and throwOnError control\n * - Detailed execution tracking (success/error/settle counts)\n * - Concurrent execution support (process multiple items simultaneously)\n *\n * The sync Queuer is lighter weight and simpler when you don't need async features,\n * return values, or execution control.\n *\n * What is Queuing?\n * Queuing is a technique for managing and processing items sequentially or with controlled concurrency.\n * Tasks are processed up to the configured concurrency limit. When a task completes,\n * the next pending task is processed if the concurrency limit allows.\n *\n * Key Features:\n * - Priority queue support via the getPriority option\n * - Configurable concurrency limit\n * - Callbacks for task success, error, completion, and queue state changes\n * - FIFO (First In First Out) or LIFO (Last In First Out) queue behavior\n * - Pause and resume processing\n * - Item expiration to remove stale items from the queue\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and queuer instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together; the handler will be called before any error is thrown\n * - The error state can be checked using the AsyncQueuer instance\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async queuer\n * - Use `onSuccess` callback to react to successful task execution and implement custom logic\n * - Use `onError` callback to react to task execution errors and implement custom error handling\n * - Use `onSettled` callback to react to task execution completion (success or error) and implement custom logic\n * - Use `onItemsChange` callback to react to items being added or removed from the queue\n * - Use `onExpire` callback to react to items expiring and implement custom logic\n * - Use `onReject` callback to react to items being rejected when the queue is full\n * - The state includes error count, expiration count, rejection count, running status, and success/settle counts\n * - State can be accessed via `asyncQueuer.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `asyncQueuer.state`\n *\n * Example usage:\n * ```ts\n * const asyncQueuer = new AsyncQueuer<string>(async (item) => {\n *   // process item\n *   return item.toUpperCase();\n * }, {\n *   concurrency: 2,\n *   onSuccess: (result) => {\n *     console.log(result);\n *   }\n * });\n *\n * asyncQueuer.addItem('hello');\n * asyncQueuer.start();\n * ```\n */\nexport class AsyncQueuer<TValue> {\n  readonly store: Store<Readonly<AsyncQueuerState<TValue>>> = new Store<\n    AsyncQueuerState<TValue>\n  >(getDefaultAsyncQueuerState<TValue>())\n  key: string | undefined\n  options: AsyncQueuerOptions<TValue>\n  asyncRetryers = new Map<\n    number,\n    AsyncRetryer<(item: TValue) => Promise<any>>\n  >()\n  #timeoutIds: Set<ReturnType<typeof setTimeout>> = new Set()\n\n  constructor(\n    public fn: (item: TValue) => Promise<any>,\n    initialOptions: AsyncQueuerOptions<TValue> = {},\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n      throwOnError: initialOptions.throwOnError ?? !initialOptions.onError,\n    }\n    const isInitiallyRunning =\n      this.options.initialState?.isRunning ?? this.options.started ?? true\n    this.#setState({\n      ...this.options.initialState,\n      isRunning: isInitiallyRunning,\n    })\n\n    if (this.options.initialState?.items) {\n      if (this.store.state.isRunning) {\n        this.#tick()\n      }\n    } else {\n      for (let i = 0; i < (this.options.initialItems?.length ?? 0); i++) {\n        const item = this.options.initialItems![i]!\n        const isLast = i === (this.options.initialItems?.length ?? 0) - 1\n        this.addItem(item, this.options.addItemsTo ??

Returns promises that can be awaited for task results\n * - Built-in retry support via AsyncRetryer integration for each queued task\n * - Abort support to cancel in-flight task executions\n * - Comprehensive error handling with onError callbacks and throwOnError control\n * - Detailed execution tracking (success/error/settle counts)\n * - Concurrent execution support (process multiple items simultaneously)\n *\n * The sync Queuer is lighter weight and simpler when you don't need async features,\n * return values, or execution control.\n *\n * What is Queuing?\n * Queuing is a technique for managing and processing items sequentially or with controlled concurrency.\n * Tasks are processed up to the configured concurrency limit. When a task completes,\n * the next pending task is processed if the concurrency limit allows.\n *\n * Key Features:\n * - Priority queue support via the getPriority option\n * - Configurable concurrency limit\n * - Callbacks for task success, error, completion, and queue state changes\n * - FIFO (First In First Out) or LIFO (Last In First Out) queue behavior\n * - Pause and resume processing\n * - Item expiration to remove stale items from the queue\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and queuer instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together; the handler will be called before any error is thrown\n * - The error state can be checked using the AsyncQueuer instance\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async queuer\n * - Use `onSuccess` callback to react to successful task execution and implement custom logic\n * - Use `onError` callback to react to task execution errors and implement custom error handling\n * - Use `onSettled` callback to react to task execution completion (success or error) and implement custom logic\n * - Use `onItemsChange` callback to react to items being added or removed from the queue\n * - Use `onExpire` callback to react to items expiring and implement custom logic\n * - Use `onReject` callback to react to items being rejected when the queue is full\n * - The state includes error count, expiration count, rejection count, running status, and success/settle counts\n * - State can be accessed via `asyncQueuer.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `asyncQueuer.state`\n *\n * Example usage:\n * ```ts\n * const asyncQueuer = new AsyncQueuer<string>(async (item) => {\n *   // process item\n *   return item.toUpperCase();\n * }, {\n *   concurrency: 2,\n *   onSuccess: (result) => {\n *     console.log(result);\n *   }\n * });\n *\n * asyncQueuer.addItem('hello');\n * asyncQueuer.start();\n * ```\n */\nexport class AsyncQueuer<TValue> {\n  readonly store: Store<Readonly<AsyncQueuerState<TValue>>> = new Store<\n    AsyncQueuerState<TValue>\n  >(getDefaultAsyncQueuerState<TValue>())\n  key: string | undefined\n  options: AsyncQueuerOptions<TValue>\n  asyncRetryers = new Map<\n    number,\n    AsyncRetryer<(item: TValue) => Promise<any>>\n  >()\n  #timeoutIds: Set<NodeJS.Timeout> = new Set()\n\n  constructor(\n    public fn: (item: TValue) => Promise<any>,\n    initialOptions: AsyncQueuerOptions<TValue> = {},\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n      throwOnError: initialOptions.throwOnError ?? !initialOptions.onError,\n    }\n    const isInitiallyRunning =\n      this.options.initialState?.isRunning ?? this.options.started ?? true\n    this.#setState({\n      ...this.options.initialState,\n      isRunning: isInitiallyRunning,\n    })\n\n    if (this.options.initialState?.items) {\n      if (this.store.state.isRunning) {\n        this.#tick()\n      }\n    } else {\n      for (let i = 0; i < (this.options.initialItems?.length ?? 0); i++) {\n        const item = this.options.initialItems![i]!\n        const isLast = i === (this.options.initialItems?.length ?? 0) - 1\n        this.addItem(item, this.options.addItemsTo ??

Returns promises that can be awaited for task results\n * - Built-in retry support via AsyncRetryer integration for each queued task\n * - Abort support to cancel in-flight task executions\n * - Comprehensive error handling with onError callbacks and throwOnError control\n * - Detailed execution tracking (success/error/settle counts)\n * - Concurrent execution support (process multiple items simultaneously)\n *\n * The sync Queuer is lighter weight and simpler when you don't need async features,\n * return values, or execution control.\n *\n * What is Queuing?\n * Queuing is a technique for managing and processing items sequentially or with controlled concurrency.\n * Tasks are processed up to the configured concurrency limit. When a task completes,\n * the next pending task is processed if the concurrency limit allows.\n *\n * Key Features:\n * - Priority queue support via the getPriority option\n * - Configurable concurrency limit\n * - Callbacks for task success, error, completion, and queue state changes\n * - FIFO (First In First Out) or LIFO (Last In First Out) queue behavior\n * - Pause and resume processing\n * - Item expiration to remove stale items from the queue\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and queuer instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together; the handler will be called before any error is thrown\n * - The error state can be checked using the AsyncQueuer instance\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async queuer\n * - Use `onSuccess` callback to react to successful task execution and implement custom logic\n * - Use `onError` callback to react to task execution errors and implement custom error handling\n * - Use `onSettled` callback to react to task execution completion (success or error) and implement custom logic\n * - Use `onItemsChange` callback to react to items being added or removed from the queue\n * - Use `onExpire` callback to react to items expiring and implement custom logic\n * - Use `onReject` callback to react to items being rejected when the queue is full\n * - The state includes error count, expiration count, rejection count, running status, and success/settle counts\n * - State can be accessed via `asyncQueuer.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `asyncQueuer.state`\n *\n * Example usage:\n * ```ts\n * const asyncQueuer = new AsyncQueuer<string>(async (item) => {\n *   // process item\n *   return item.toUpperCase();\n * }, {\n *   concurrency: 2,\n *   onSuccess: (result) => {\n *     console.log(result);\n *   }\n * });\n *\n * asyncQueuer.addItem('hello');\n * asyncQueuer.start();\n * ```\n */\nexport class AsyncQueuer<TValue> {\n  readonly store: Store<Readonly<AsyncQueuerState<TValue>>> = new Store<\n    AsyncQueuerState<TValue>\n  >(getDefaultAsyncQueuerState<TValue>())\n  key: string | undefined\n  options: AsyncQueuerOptions<TValue>\n  asyncRetryers = new Map<\n    number,\n    AsyncRetryer<(item: TValue) => Promise<any>>\n  >()\n  #timeoutIds: Set<ReturnType<typeof setTimeout>> = new Set()\n\n  constructor(\n    public fn: (item: TValue) => Promise<any>,\n    initialOptions: AsyncQueuerOptions<TValue> = {},\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n      throwOnError: initialOptions.throwOnError ?? !initialOptions.onError,\n    }\n    const isInitiallyRunning =\n      this.options.initialState?.isRunning ?? this.options.started ?? true\n    this.#setState({\n      ...this.options.initialState,\n      isRunning: isInitiallyRunning,\n    })\n\n    if (this.options.initialState?.items) {\n      if (this.store.state.isRunning) {\n        this.#tick()\n      }\n    } else {\n      for (let i = 0; i < (this.options.initialItems?.length ?? 0); i++) {\n        const item = this.options.initialItems![i]!\n        const isLast = i === (this.options.initialItems?.length ?? 0) - 1\n        this.addItem(item, this.options.addItemsTo ??

This can lead to \"bursty\" behavior where\n * all executions happen immediately, followed by a complete block.\n *\n * Window Types:\n * - 'fixed': A strict window that resets after the window period. All executions within the window count\n *   towards the limit, and the window resets completely after the period.\n * - 'sliding': A rolling window that allows executions as old ones expire. This provides a more\n *   consistent rate of execution over time.\n *\n * When to Use Rate Limiting:\n * Rate limiting is best used for hard API limits or resource constraints. For UI updates or\n * smoothing out frequent events, throttling or debouncing usually provide better user experience.\n * - Throttling: Ensures consistent spacing between executions (e.g. max once per 200ms)\n * - Debouncing: Waits for a pause in calls before executing (e.g. after 500ms of no calls)\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the rate limiter\n * - `initialState` can be a partial state object\n * - Use `onSuccess` callback to react to successful function execution and implement custom logic\n * - Use `onError` callback to react to function execution errors and implement custom error handling\n * - Use `onSettled` callback to react to function execution completion (success or error) and implement custom logic\n * - Use `onReject` callback to react to executions being rejected when rate limit is exceeded\n * - The state includes execution times, success/error counts, and current execution status\n * - State can be accessed via `asyncRateLimiter.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `asyncRateLimiter.state`\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and rate limiter instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the underlying AsyncRateLimiter instance\n * - Rate limit rejections (when limit is exceeded) are handled separately from execution errors via the `onReject` handler\n *\n * @example\n * ```ts\n * const rateLimiter = new AsyncRateLimiter(\n *   async (id: string) => await api.getData(id),\n *   {\n *     limit: 5,\n *     window: 1000,\n *     windowType: 'sliding',\n *     onError: (error) => {\n *       console.error('API call failed:', error);\n *     },\n *     onReject: (limiter) => {\n *       console.log(`Rate limit exceeded.

This can lead to \"bursty\" behavior where\n * all executions happen immediately, followed by a complete block.\n *\n * Window Types:\n * - 'fixed': A strict window that resets after the window period. All executions within the window count\n *   towards the limit, and the window resets completely after the period.\n * - 'sliding': A rolling window that allows executions as old ones expire. This provides a more\n *   consistent rate of execution over time.\n *\n * Configuration Options:\n * - `limit`: Maximum number of executions allowed within the window (required)\n * - `window`: Time window in milliseconds (required)\n * - `windowType`: 'fixed' or 'sliding' (default: 'fixed')\n * - `enabled`: Whether the rate limiter is enabled (default: true)\n * - `asyncRetryerOptions`: Configure retry behavior for executions\n *\n * When to Use Rate Limiting:\n * Rate limiting is best used for hard API limits or resource constraints.

This can lead to \"bursty\" behavior where\n * all executions happen immediately, followed by a complete block.\n *\n * Window Types:\n * - 'fixed': A strict window that resets after the window period. All executions within the window count\n *   towards the limit, and the window resets completely after the period.\n * - 'sliding': A rolling window that allows executions as old ones expire. This provides a more\n *   consistent rate of execution over time.\n *\n * When to Use Rate Limiting:\n * Rate limiting is best used for hard API limits or resource constraints. For UI updates or\n * smoothing out frequent events, throttling or debouncing usually provide better user experience.\n * - Throttling: Ensures consistent spacing between executions (e.g. max once per 200ms)\n * - Debouncing: Waits for a pause in calls before executing (e.g. after 500ms of no calls)\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the rate limiter\n * - `initialState` can be a partial state object\n * - Use `onSuccess` callback to react to successful function execution and implement custom logic\n * - Use `onError` callback to react to function execution errors and implement custom error handling\n * - Use `onSettled` callback to react to function execution completion (success or error) and implement custom logic\n * - Use `onReject` callback to react to executions being rejected when rate limit is exceeded\n * - The state includes execution times, success/error counts, and current execution status\n * - State can be accessed via `asyncRateLimiter.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `asyncRateLimiter.state`\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and rate limiter instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the underlying AsyncRateLimiter instance\n * - Rate limit rejections (when limit is exceeded) are handled separately from execution errors via the `onReject` handler\n *\n * @example\n * ```ts\n * const rateLimiter = new AsyncRateLimiter(\n *   async (id: string) => await api.getData(id),\n *   {\n *     limit: 5,\n *     window: 1000,\n *     windowType: 'sliding',\n *     onError: (error) => {\n *       console.error('API call failed:', error);\n *     },\n *     onReject: (limiter) => {\n *       console.log(`Rate limit exceeded. Try again in ${limiter.getMsUntilNextWindow()}ms`);\n *     }\n *   }\n * );\n *\n * // Will execute immediately until limit reached, then block\n * // Returns the API response directly\n * const data = await rateLimiter.maybeExecute('123');\n * ```\n */\nexport class AsyncRateLimiter<TFn extends AnyAsyncFunction> {\n  readonly store: Store<Readonly<AsyncRateLimiterState<TFn>>> = new Store<\n    AsyncRateLimiterState<TFn>\n  >(getDefaultAsyncRateLimiterState<TFn>())\n  key: string | undefined\n  options: AsyncRateLimiterOptions<TFn>\n  asyncRetryers = new Map<number, AsyncRetryer<TFn>>()\n  #timeoutIds: Set<ReturnType<typeof setTimeout>> = new Set()\n\n  constructor(\n    public fn: TFn,\n    initialOptions: AsyncRateLimiterOptions<TFn>,\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n      throwOnError: initialOptions.throwOnError ?? !initialOptions.onError,\n    }\n    this.#setState(this.options.initialState ?? {})\n    for (const executionTime of this.#getExecutionTimesInWindow()) {\n      this.#setCleanupTimeout(executionTime)\n    }\n\n    if (this.key) {\n      pacerEventClient.on('d-AsyncRateLimiter', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(\n          event.payload.store.state as Partial<AsyncRateLimiterState<TFn>>,\n        )\n        this.setOptions(\n          event.payload.options as Partial<AsyncRateLimiterOptions<TFn>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the async rate limiter options\n   */\n  setOptions = (newOptions: Partial<AsyncRateLimiterOptions<TFn>>): void => {\n    this.options = { ...this.options, ...newOptions }\n  }\n\n  #setState = (newState: Partial<AsyncRateLimiterState<TFn>>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const isExceeded = combinedState.executionTimes.length >= this.#getLimit()\n      const status = !this.#getEnabled()\n        ?

This can lead to \"bursty\" behavior where\n * all executions happen immediately, followed by a complete block.\n *\n * Window Types:\n * - 'fixed': A strict window that resets after the window period. All executions within the window count\n *   towards the limit, and the window resets completely after the period.\n * - 'sliding': A rolling window that allows executions as old ones expire. This provides a more\n *   consistent rate of execution over time.\n *\n * Configuration Options:\n * - `limit`: Maximum number of executions allowed within the window (required)\n * - `window`: Time window in milliseconds (required)\n * - `windowType`: 'fixed' or 'sliding' (default: 'fixed')\n * - `enabled`: Whether the rate limiter is enabled (default: true)\n * - `asyncRetryerOptions`: Configure retry behavior for executions\n *\n * When to Use Rate Limiting:\n * Rate limiting is best used for hard API limits or resource constraints. For UI updates or\n * smoothing out frequent events, throttling or debouncing usually provide better user experience.\n * - A rate limiter will allow all executions until the limit is reached, then block all subsequent calls until the window resets\n * - A throttler ensures even spacing between executions, which can be better for consistent performance\n * - A debouncer collapses multiple calls into one, which is better for handling bursts of events\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and rate limiter instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the underlying AsyncRateLimiter instance\n * - Rate limit rejections (when limit is exceeded) are handled separately from execution errors via the `onReject` handler\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the rate limiter\n * - `initialState` can be a partial state object\n * - Use `onSuccess` callback to react to successful function execution and implement custom logic\n * - Use `onError` callback to react to function execution errors and implement custom error handling\n * - Use `onSettled` callback to react to function execution completion (success or error) and implement custom logic\n * - Use `onReject` callback to react to executions being rejected when rate limit is exceeded\n * - The state includes execution times, success/error counts, and current execution status\n * - State can be accessed via the underlying AsyncRateLimiter instance's `store.state` property\n * - When using framework adapters (React/Solid), state is accessed from the hook's state property\n *\n * @example\n * ```ts\n * // Rate limit to 5 calls per minute with a sliding window\n * const rateLimited = asyncRateLimit(makeApiCall, {\n *   limit: 5,\n *   window: 60000,\n *   windowType: 'sliding',\n *   onError: (error) => {\n *     console.error('API call failed:', error);\n *   },\n *   onReject: (rateLimiter) => {\n *     console.log(`Rate limit exceeded. Try again in ${rateLimiter.getMsUntilNextWindow()}ms`);\n *   }\n * });\n *\n * // First 5 calls will execute immediately\n * // Additional calls will be rejected until the minute window resets\n * // Returns the API response directly\n * const result = await rateLimited();\n *\n * // For more even execution, consider using throttle instead:\n * const throttled = throttle(makeApiCall, { wait: 12000 }); // One call every 12 seconds\n * ```\n */\nexport function asyncRateLimit<TFn extends AnyAsyncFunction>(\n  fn: TFn,\n  initialOptions: AsyncRateLimiterOptions<TFn>,\n) {\n  const rateLimiter = new AsyncRateLimiter(fn, initialOptions)\n  return rateLimiter.maybeExecute\n}\n"],"mappings":";;;;;;;AAkDA,SAAS,kCAEuB;AAC9B,QAAO;EACL,YAAY;EACZ,gBAAgB,EAAE;EAClB,YAAY;EACZ,aAAa;EACb,YAAY;EACZ,mBAAmB;EACnB,gBAAgB;EAChB,aAAa;EACb,QAAQ;EACR,cAAc;EACf;;;;;AAmFH,SAAgB,wBAKd,SAA6B;AAC7B,QAAO;;AAGT,MAAM,iBAGF;CACF,qBAAqB,EACnB,aAAa,GACd;CACD,SAAS;CACT,OAAO;CACP,QAAQ;CACR,YAAY;CACZ,cAAc;CACf;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AA4ED,IAAa,mBAAb,MAA4D;CAO1D,8BAAkD,IAAI,KAAK;CAE3D,YACE,AAAO,IACP,gBACA;EAFO;eATqD,IAAIA,sBAEhE,iCAAsC,CAAC;uCAGzB,IAAI,KAAgC;qBAkCtC,eAA4D;AACxE,QAAK,UAAU;IAAE,GAAG,KAAK;IAAS,GAAG;IAAY;;sBAwEpC,OACb,GAAG,SACsC;AACzC,SAAKC,SAAU,EACb,mBAAmB,KAAK,MAAM,MAAM,oBAAoB,GACzD,CAAC;AAEF,SAAKC,sBAAuB;AAI5B,OAF+B,MAAKC,2BAA4B,CAErC,SAAS,MAAKC,UAAW,EAAE;AACpD,UAAM,MAAKC,QAAS,GAAG,KAAK;AAC5B,WAAO,KAAK,MAAM,MAAM;;AAG1B,SAAKJ,SAAU,EACb,gBAAgB,KAAK,MAAM,MAAM,iBAAiB,GACnD,CAAC;AACF,QAAK,QAAQ,WAAW,MAAM,KAAK;;oCAkHA;GACnC,MAAM,yBAAyB,MAAKE,2BAA4B;AAChE,UAAO,KAAK,IAAI,GAAG,MAAKC,UAAW,GAAG,uBAAuB,OAAO;;oCAQjC;AACnC,OAAI,KAAK,sBAAsB,GAAG,EAChC,QAAO;AAGT,WADwB,KAAK,MAAM,MAAM,eAAe,MAAM,YACrC,MAAKE,WAAY,GAAG,KAAK,KAAK;;yBAuBvC,sBAAmD;GACnE,MAAM,QAAQ,qBAAqB,KAAK,MAAM,MAAM;AAEpD,UADgB,KAAK,cAAc,IAAI,MAAM,EAC7B,gBAAgB,IAAI;;qBAOlB;AAClB,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;AACxD,QAAK,cAAc,OAAO;AAC1B,SAAKL,SAAU,EACb,aAAa,OACd,CAAC;;qBAMgB;AAClB,SAAKA,SAAU,iCAAiC,CAAC;AACjD,SAAKM,eAAgB;AACrB,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;;AAvSxD,OAAK,MAAM,eAAe;AAC1B,OAAK,UAAU;GACb,GAAG;GACH,GAAG;GACH,cAAc,eAAe,gBAAgB,CAAC,eAAe;GAC9D;AACD,QAAKN,SAAU,KAAK,QAAQ,gBAAgB,EAAE,CAAC;AAC/C,OAAK,MAAM,iBAAiB,MAAKE,2BAA4B,CAC3D,OAAKK,kBAAmB,cAAc;AAGxC,MAAI,KAAK,IACP,uCAAiB,GAAG,uBAAuB,UAAU;AACnD,OAAI,MAAM,QAAQ,QAAQ,KAAK,IAAK;AACpC,SAAKP,SACH,MAAM,QAAQ,MAAM,MACrB;AACD,QAAK,WACH,MAAM,QAAQ,QACf;IACD;;CAWN,aAAa,aAAwD;AACnE,OAAK,MAAM,UAAU,UAAU;GAC7B,MAAM,gBAAgB;IACpB,GAAG;IACH,GAAG;IACJ;GACD,MAAM,aAAa,cAAc,eAAe,UAAU,MAAKG,UAAW;GAC1E,MAAM,SAAS,CAAC,MAAKK,YAAa,GAC9B,aACA,cAAc,cACZ,cACA,aACE,aACA;AACR,UAAO;IACL,GAAG;IACH;IACA;IACD;IACD;AACF,kCAAW,oBAAoB,KAAK;;;;;CAMtC,oBAA6B;AAC3B,SAAO,CAAC,CAACC,mCAAqB,KAAK,QAAQ,SAAS,KAAK;;;;;CAM3D,kBAA0B;AACxB,SAAOA,mCAAqB,KAAK,QAAQ,OAAO,KAAK;;;;;CAMvD,mBAA2B;AACzB,SAAOA,mCAAqB,KAAK,QAAQ,QAAQ,KAAK;;CAmDxD,WAAW,OACT,GAAG,SACsC;AACzC,MAAI,CAAC,MAAKD,YAAa,CAAE;EAEzB,MAAM,sBAAsB,KAAK,MAAM,MAAM;EAC7C,MAAM,MAAM,KAAK,KAAK;EACtB,MAAM,iBAAiB,CAAC,GAAG,KAAK,MAAM,MAAM,gBAAgB,IAAI;AAChE,QAAKR,SAAU;GACb,aAAa;GACb;GACD,CAAC;AAEF,MAAI;GAEF,MAAM,sBAAsB,IAAIU,mCAAa,KAAK,IAAI;IACpD,GAAG,KAAK,QAAQ;IAChB,KAAK,GAAG,KAAK,IAAI,WAAW;IAC7B,CAAC;AACF,QAAK,cAAc,IAAI,qBAAqB,oBAAoB;GAChE,MAAM,SAAS,MAAM,oBAAoB,QAAQ,GAAG,KAAK;AACzD,SAAKH,kBAAmB,IAAI;AAC5B,SAAKP,SAAU;IACb,cAAc,KAAK,MAAM,MAAM,eAAe;IAC9C,YAAY;IACb,CAAC;AACF,QAAK,QAAQ,YAAY,QAA2B,MAAM,KAAK;WACxD,OAAO;AACd,SAAKA,SAAU,EACb,YAAY,KAAK,MAAM,MAAM,aAAa,GAC3C,CAAC;AACF,QAAK,QAAQ,UAAU,OAAgB,MAAM,KAAK;AAClD,OAAI,KAAK,QAAQ,aACf,OAAM;YAEA;AACR,QAAK,cAAc,OAAO,oBAAoB;AAC9C,SAAKA,SAAU;IACb,aAAa;IACb,aAAa,KAAK,MAAM,MAAM,cAAc;IAC7C,CAAC;AACF,QAAK,QAAQ,YAAY,MAAM,KAAK;;AAGtC,SAAO,KAAK,MAAM,MAAM;;CAG1B,mCAAkD;AAChD,MAAI,KAAK,QAAQ,eAAe,UAE9B,QAAO,KAAK,MAAM,MAAM,eAAe,QACpC,SAAS,OAAO,KAAK,KAAK,GAAG,MAAKK,WAAY,CAChD;OACI;AAGL,OAAI,KAAK,MAAM,MAAM,eAAe,WAAW,EAC7C,QAAO,EAAE;GAGX,MAAM,cADkB,KAAK,IAAI,GAAG,KAAK,MAAM,MAAM,eAAe;GAEpE,MAAM,YAAY,cAAc,MAAKA,WAAY;AAIjD,OAHY,KAAK,KAAK,GAGZ,UACR,QAAO,EAAE;AAIX,UAAO,KAAK,MAAM,MAAM,eAAe,QACpC,SAAS,QAAQ,eAAe,QAAQ,UAC1C;;;CAIL,sBAAsB,kBAAgC;AACpD,MACE,KAAK,QAAQ,eAAe,aAC5B,MAAKM,WAAY,SAAS,GAC1B;GAEA,MAAM,sBAAsB,gBADhB,KAAK,KAAK,GAC4B,MAAKN,WAAY,GAAG;GACtE,MAAM,YAAY,iBAAiB;AACjC,UAAKJ,sBAAuB;AAC5B,UAAKW,aAAc,UAAU;MAC5B,oBAAoB;AACvB,SAAKD,WAAY,IAAI,UAAU;;;CAInC,iBAAiB,cAAmD;AAClE,eAAa,UAAU;AACvB,QAAKA,WAAY,OAAO,UAAU;;CAGpC,uBAA6B;AAC3B,QAAKA,WAAY,SAAS,cAAc,aAAa,UAAU,CAAC;AAChE,QAAKA,WAAY,OAAO;;CAG1B,8BAAoC;AAClC,QAAKX,SAAU,EACb,gBAAgB,MAAKE,2BAA4B,EAClD,CAAC;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AA4JN,SAAgB,eACd,IACA,gBACA;AAEA,QADoB,IAAI,iBAAiB,IAAI,eAAe,CACzC"}

This can lead to \"bursty\" behavior where\n * all executions happen immediately, followed by a complete block.\n *\n * Window Types:\n * - 'fixed': A strict window that resets after the window period. All executions within the window count\n *   towards the limit, and the window resets completely after the period.\n * - 'sliding': A rolling window that allows executions as old ones expire. This provides a more\n *   consistent rate of execution over time.\n *\n * When to Use Rate Limiting:\n * Rate limiting is best used for hard API limits or resource constraints. For UI updates or\n * smoothing out frequent events, throttling or debouncing usually provide better user experience.\n * - Throttling: Ensures consistent spacing between executions (e.g. max once per 200ms)\n * - Debouncing: Waits for a pause in calls before executing (e.g. after 500ms of no calls)\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the rate limiter\n * - `initialState` can be a partial state object\n * - Use `onSuccess` callback to react to successful function execution and implement custom logic\n * - Use `onError` callback to react to function execution errors and implement custom error handling\n * - Use `onSettled` callback to react to function execution completion (success or error) and implement custom logic\n * - Use `onReject` callback to react to executions being rejected when rate limit is exceeded\n * - The state includes execution times, success/error counts, and current execution status\n * - State can be accessed via `asyncRateLimiter.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `asyncRateLimiter.state`\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and rate limiter instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the underlying AsyncRateLimiter instance\n * - Rate limit rejections (when limit is exceeded) are handled separately from execution errors via the `onReject` handler\n *\n * @example\n * ```ts\n * const rateLimiter = new AsyncRateLimiter(\n *   async (id: string) => await api.getData(id),\n *   {\n *     limit: 5,\n *     window: 1000,\n *     windowType: 'sliding',\n *     onError: (error) => {\n *       console.error('API call failed:', error);\n *     },\n *     onReject: (limiter) => {\n *       console.log(`Rate limit exceeded. Try again in ${limiter.getMsUntilNextWindow()}ms`);\n *     }\n *   }\n * );\n *\n * // Will execute immediately until limit reached, then block\n * // Returns the API response directly\n * const data = await rateLimiter.maybeExecute('123');\n * ```\n */\nexport class AsyncRateLimiter<TFn extends AnyAsyncFunction> {\n  readonly store: Store<Readonly<AsyncRateLimiterState<TFn>>> = new Store<\n    AsyncRateLimiterState<TFn>\n  >(getDefaultAsyncRateLimiterState<TFn>())\n  key: string | undefined\n  options: AsyncRateLimiterOptions<TFn>\n  asyncRetryers = new Map<number, AsyncRetryer<TFn>>()\n  #timeoutIds: Set<NodeJS.Timeout> = new Set()\n\n  constructor(\n    public fn: TFn,\n    initialOptions: AsyncRateLimiterOptions<TFn>,\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n      throwOnError: initialOptions.throwOnError ?? !initialOptions.onError,\n    }\n    this.#setState(this.options.initialState ?? {})\n    for (const executionTime of this.#getExecutionTimesInWindow()) {\n      this.#setCleanupTimeout(executionTime)\n    }\n\n    if (this.key) {\n      pacerEventClient.on('d-AsyncRateLimiter', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(\n          event.payload.store.state as Partial<AsyncRateLimiterState<TFn>>,\n        )\n        this.setOptions(\n          event.payload.options as Partial<AsyncRateLimiterOptions<TFn>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the async rate limiter options\n   */\n  setOptions = (newOptions: Partial<AsyncRateLimiterOptions<TFn>>): void => {\n    this.options = { ...this.options, ...newOptions }\n  }\n\n  #setState = (newState: Partial<AsyncRateLimiterState<TFn>>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const isExceeded = combinedState.executionTimes.length >= this.#getLimit()\n      const status = !this.#getEnabled()\n        ?

Try again in ${rateLimiter.getMsUntilNextWindow()}ms`);\n *   }\n * });\n *\n * // First 5 calls will execute immediately\n * // Additional calls will be rejected until the minute window resets\n * // Returns the API response directly\n * const result = await rateLimited();\n *\n * // For more even execution, consider using throttle instead:\n * const throttled = throttle(makeApiCall, { wait: 12000 }); // One call every 12 seconds\n * ```\n */\nexport function asyncRateLimit<TFn extends AnyAsyncFunction>(\n  fn: TFn,\n  initialOptions: AsyncRateLimiterOptions<TFn>,\n) {\n  const rateLimiter = new AsyncRateLimiter(fn, initialOptions)\n  return rateLimiter.maybeExecute\n}\n"],"mappings":";;;;;;AAkDA,SAAS,kCAEuB;AAC9B,QAAO;EACL,YAAY;EACZ,gBAAgB,EAAE;EAClB,YAAY;EACZ,aAAa;EACb,YAAY;EACZ,mBAAmB;EACnB,gBAAgB;EAChB,aAAa;EACb,QAAQ;EACR,cAAc;EACf;;;;;AAmFH,SAAgB,wBAKd,SAA6B;AAC7B,QAAO;;AAGT,MAAM,iBAGF;CACF,qBAAqB,EACnB,aAAa,GACd;CACD,SAAS;CACT,OAAO;CACP,QAAQ;CACR,YAAY;CACZ,cAAc;CACf;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AA4ED,IAAa,mBAAb,MAA4D;CAO1D,8BAAmC,IAAI,KAAK;CAE5C,YACE,AAAO,IACP,gBACA;EAFO;eATqD,IAAI,MAEhE,iCAAsC,CAAC;uCAGzB,IAAI,KAAgC;qBAkCtC,eAA4D;AACxE,QAAK,UAAU;IAAE,GAAG,KAAK;IAAS,GAAG;IAAY;;sBAwEpC,OACb,GAAG,SACsC;AACzC,SAAKA,SAAU,EACb,mBAAmB,KAAK,MAAM,MAAM,oBAAoB,GACzD,CAAC;AAEF,SAAKC,sBAAuB;AAI5B,OAF+B,MAAKC,2BAA4B,CAErC,SAAS,MAAKC,UAAW,EAAE;AACpD,UAAM,MAAKC,QAAS,GAAG,KAAK;AAC5B,WAAO,KAAK,MAAM,MAAM;;AAG1B,SAAKJ,SAAU,EACb,gBAAgB,KAAK,MAAM,MAAM,iBAAiB,GACnD,CAAC;AACF,QAAK,QAAQ,WAAW,MAAM,KAAK;;oCAkHA;GACnC,MAAM,yBAAyB,MAAKE,2BAA4B;AAChE,UAAO,KAAK,IAAI,GAAG,MAAKC,UAAW,GAAG,uBAAuB,OAAO;;oCAQjC;AACnC,OAAI,KAAK,sBAAsB,GAAG,EAChC,QAAO;AAGT,WADwB,KAAK,MAAM,MAAM,eAAe,MAAM,YACrC,MAAKE,WAAY,GAAG,KAAK,KAAK;;yBAuBvC,sBAAmD;GACnE,MAAM,QAAQ,qBAAqB,KAAK,MAAM,MAAM;AAEpD,UADgB,KAAK,cAAc,IAAI,MAAM,EAC7B,gBAAgB,IAAI;;qBAOlB;AAClB,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;AACxD,QAAK,cAAc,OAAO;AAC1B,SAAKL,SAAU,EACb,aAAa,OACd,CAAC;;qBAMgB;AAClB,SAAKA,SAAU,iCAAiC,CAAC;AACjD,SAAKM,eAAgB;AACrB,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;;AAvSxD,OAAK,MAAM,eAAe;AAC1B,OAAK,UAAU;GACb,GAAG;GACH,GAAG;GACH,cAAc,eAAe,gBAAgB,CAAC,eAAe;GAC9D;AACD,QAAKN,SAAU,KAAK,QAAQ,gBAAgB,EAAE,CAAC;AAC/C,OAAK,MAAM,iBAAiB,MAAKE,2BAA4B,CAC3D,OAAKK,kBAAmB,cAAc;AAGxC,MAAI,KAAK,IACP,kBAAiB,GAAG,uBAAuB,UAAU;AACnD,OAAI,MAAM,QAAQ,QAAQ,KAAK,IAAK;AACpC,SAAKP,SACH,MAAM,QAAQ,MAAM,MACrB;AACD,QAAK,WACH,MAAM,QAAQ,QACf;IACD;;CAWN,aAAa,aAAwD;AACnE,OAAK,MAAM,UAAU,UAAU;GAC7B,MAAM,gBAAgB;IACpB,GAAG;IACH,GAAG;IACJ;GACD,MAAM,aAAa,cAAc,eAAe,UAAU,MAAKG,UAAW;GAC1E,MAAM,SAAS,CAAC,MAAKK,YAAa,GAC9B,aACA,cAAc,cACZ,cACA,aACE,aACA;AACR,UAAO;IACL,GAAG;IACH;IACA;IACD;IACD;AACF,aAAW,oBAAoB,KAAK;;;;;CAMtC,oBAA6B;AAC3B,SAAO,CAAC,CAAC,qBAAqB,KAAK,QAAQ,SAAS,KAAK;;;;;CAM3D,kBAA0B;AACxB,SAAO,qBAAqB,KAAK,QAAQ,OAAO,KAAK;;;;;CAMvD,mBAA2B;AACzB,SAAO,qBAAqB,KAAK,QAAQ,QAAQ,KAAK;;CAmDxD,WAAW,OACT,GAAG,SACsC;AACzC,MAAI,CAAC,MAAKA,YAAa,CAAE;EAEzB,MAAM,sBAAsB,KAAK,MAAM,MAAM;EAC7C,MAAM,MAAM,KAAK,KAAK;EACtB,MAAM,iBAAiB,CAAC,GAAG,KAAK,MAAM,MAAM,gBAAgB,IAAI;AAChE,QAAKR,SAAU;GACb,aAAa;GACb;GACD,CAAC;AAEF,MAAI;GAEF,MAAM,sBAAsB,IAAI,aAAa,KAAK,IAAI;IACpD,GAAG,KAAK,QAAQ;IAChB,KAAK,GAAG,KAAK,IAAI,WAAW;IAC7B,CAAC;AACF,QAAK,cAAc,IAAI,qBAAqB,oBAAoB;GAChE,MAAM,SAAS,MAAM,oBAAoB,QAAQ,GAAG,KAAK;AACzD,SAAKO,kBAAmB,IAAI;AAC5B,SAAKP,SAAU;IACb,cAAc,KAAK,MAAM,MAAM,eAAe;IAC9C,YAAY;IACb,CAAC;AACF,QAAK,QAAQ,YAAY,QAA2B,MAAM,KAAK;WACxD,OAAO;AACd,SAAKA,SAAU,EACb,YAAY,KAAK,MAAM,MAAM,aAAa,GAC3C,CAAC;AACF,QAAK,QAAQ,UAAU,OAAgB,MAAM,KAAK;AAClD,OAAI,KAAK,QAAQ,aACf,OAAM;YAEA;AACR,QAAK,cAAc,OAAO,oBAAoB;AAC9C,SAAKA,SAAU;IACb,aAAa;IACb,aAAa,KAAK,MAAM,MAAM,cAAc;IAC7C,CAAC;AACF,QAAK,QAAQ,YAAY,MAAM,KAAK;;AAGtC,SAAO,KAAK,MAAM,MAAM;;CAG1B,mCAAkD;AAChD,MAAI,KAAK,QAAQ,eAAe,UAE9B,QAAO,KAAK,MAAM,MAAM,eAAe,QACpC,SAAS,OAAO,KAAK,KAAK,GAAG,MAAKK,WAAY,CAChD;OACI;AAGL,OAAI,KAAK,MAAM,MAAM,eAAe,WAAW,EAC7C,QAAO,EAAE;GAGX,MAAM,cADkB,KAAK,IAAI,GAAG,KAAK,MAAM,MAAM,eAAe;GAEpE,MAAM,YAAY,cAAc,MAAKA,WAAY;AAIjD,OAHY,KAAK,KAAK,GAGZ,UACR,QAAO,EAAE;AAIX,UAAO,KAAK,MAAM,MAAM,eAAe,QACpC,SAAS,QAAQ,eAAe,QAAQ,UAC1C;;;CAIL,sBAAsB,kBAAgC;AACpD,MACE,KAAK,QAAQ,eAAe,aAC5B,MAAKI,WAAY,SAAS,GAC1B;GAEA,MAAM,sBAAsB,gBADhB,KAAK,KAAK,GAC4B,MAAKJ,WAAY,GAAG;GACtE,MAAM,YAAY,iBAAiB;AACjC,UAAKJ,sBAAuB;AAC5B,UAAKS,aAAc,UAAU;MAC5B,oBAAoB;AACvB,SAAKD,WAAY,IAAI,UAAU;;;CAInC,iBAAiB,cAAoC;AACnD,eAAa,UAAU;AACvB,QAAKA,WAAY,OAAO,UAAU;;CAGpC,uBAA6B;AAC3B,QAAKA,WAAY,SAAS,cAAc,aAAa,UAAU,CAAC;AAChE,QAAKA,WAAY,OAAO;;CAG1B,8BAAoC;AAClC,QAAKT,SAAU,EACb,gBAAgB,MAAKE,2BAA4B,EAClD,CAAC;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AA4JN,SAAgB,eACd,IACA,gBACA;AAEA,QADoB,IAAI,iBAAiB,IAAI,eAAe,CACzC"}

This can lead to \"bursty\" behavior where\n * all executions happen immediately, followed by a complete block.\n *\n * Window Types:\n * - 'fixed': A strict window that resets after the window period. All executions within the window count\n *   towards the limit, and the window resets completely after the period.\n * - 'sliding': A rolling window that allows executions as old ones expire. This provides a more\n *   consistent rate of execution over time.\n *\n * When to Use Rate Limiting:\n * Rate limiting is best used for hard API limits or resource constraints. For UI updates or\n * smoothing out frequent events, throttling or debouncing usually provide better user experience.\n * - Throttling: Ensures consistent spacing between executions (e.g. max once per 200ms)\n * - Debouncing: Waits for a pause in calls before executing (e.g. after 500ms of no calls)\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the rate limiter\n * - `initialState` can be a partial state object\n * - Use `onSuccess` callback to react to successful function execution and implement custom logic\n * - Use `onError` callback to react to function execution errors and implement custom error handling\n * - Use `onSettled` callback to react to function execution completion (success or error) and implement custom logic\n * - Use `onReject` callback to react to executions being rejected when rate limit is exceeded\n * - The state includes execution times, success/error counts, and current execution status\n * - State can be accessed via `asyncRateLimiter.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `asyncRateLimiter.state`\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and rate limiter instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the underlying AsyncRateLimiter instance\n * - Rate limit rejections (when limit is exceeded) are handled separately from execution errors via the `onReject` handler\n *\n * @example\n * ```ts\n * const rateLimiter = new AsyncRateLimiter(\n *   async (id: string) => await api.getData(id),\n *   {\n *     limit: 5,\n *     window: 1000,\n *     windowType: 'sliding',\n *     onError: (error) => {\n *       console.error('API call failed:', error);\n *     },\n *     onReject: (limiter) => {\n *       console.log(`Rate limit exceeded.

This can lead to \"bursty\" behavior where\n * all executions happen immediately, followed by a complete block.\n *\n * Window Types:\n * - 'fixed': A strict window that resets after the window period. All executions within the window count\n *   towards the limit, and the window resets completely after the period.\n * - 'sliding': A rolling window that allows executions as old ones expire. This provides a more\n *   consistent rate of execution over time.\n *\n * Configuration Options:\n * - `limit`: Maximum number of executions allowed within the window (required)\n * - `window`: Time window in milliseconds (required)\n * - `windowType`: 'fixed' or 'sliding' (default: 'fixed')\n * - `enabled`: Whether the rate limiter is enabled (default: true)\n * - `asyncRetryerOptions`: Configure retry behavior for executions\n *\n * When to Use Rate Limiting:\n * Rate limiting is best used for hard API limits or resource constraints. For UI updates or\n * smoothing out frequent events, throttling or debouncing usually provide better user experience.\n * - A rate limiter will allow all executions until the limit is reached, then block all subsequent calls until the window resets\n * - A throttler ensures even spacing between executions, which can be better for consistent performance\n * - A debouncer collapses multiple calls into one, which is better for handling bursts of events\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and rate limiter instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the underlying AsyncRateLimiter instance\n * - Rate limit rejections (when limit is exceeded) are handled separately from execution errors via the `onReject` handler\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the rate limiter\n * - `initialState` can be a partial state object\n * - Use `onSuccess` callback to react to successful function execution and implement custom logic\n * - Use `onError` callback to react to function execution errors and implement custom error handling\n * - Use `onSettled` callback to react to function execution completion (success or error) and implement custom logic\n * - Use `onReject` callback to react to executions being rejected when rate limit is exceeded\n * - The state includes execution times, success/error counts, and current execution status\n * - State can be accessed via the underlying AsyncRateLimiter instance's `store.state` property\n * - When using framework adapters (React/Solid), state is accessed from the hook's state property\n *\n * @example\n * ```ts\n * // Rate limit to 5 calls per minute with a sliding window\n * const rateLimited = asyncRateLimit(makeApiCall, {\n *   limit: 5,\n *   window: 60000,\n *   windowType: 'sliding',\n *   onError: (error) => {\n *     console.error('API call failed:', error);\n *   },\n *   onReject: (rateLimiter) => {\n *     console.log(`Rate limit exceeded. Try again in ${rateLimiter.getMsUntilNextWindow()}ms`);\n *   }\n * });\n *\n * // First 5 calls will execute immediately\n * // Additional calls will be rejected until the minute window resets\n * // Returns the API response directly\n * const result = await rateLimited();\n *\n * // For more even execution, consider using throttle instead:\n * const throttled = throttle(makeApiCall, { wait: 12000 }); // One call every 12 seconds\n * ```\n */\nexport function asyncRateLimit<TFn extends AnyAsyncFunction>(\n  fn: TFn,\n  initialOptions: AsyncRateLimiterOptions<TFn>,\n) {\n  const rateLimiter = new AsyncRateLimiter(fn, initialOptions)\n  return rateLimiter.maybeExecute\n}\n"],"mappings":";;;;;;AAkDA,SAAS,kCAEuB;AAC9B,QAAO;EACL,YAAY;EACZ,gBAAgB,EAAE;EAClB,YAAY;EACZ,aAAa;EACb,YAAY;EACZ,mBAAmB;EACnB,gBAAgB;EAChB,aAAa;EACb,QAAQ;EACR,cAAc;EACf;;;;;AAmFH,SAAgB,wBAKd,SAA6B;AAC7B,QAAO;;AAGT,MAAM,iBAGF;CACF,qBAAqB,EACnB,aAAa,GACd;CACD,SAAS;CACT,OAAO;CACP,QAAQ;CACR,YAAY;CACZ,cAAc;CACf;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AA4ED,IAAa,mBAAb,MAA4D;CAO1D,8BAAkD,IAAI,KAAK;CAE3D,YACE,AAAO,IACP,gBACA;EAFO;eATqD,IAAI,MAEhE,iCAAsC,CAAC;uCAGzB,IAAI,KAAgC;qBAkCtC,eAA4D;AACxE,QAAK,UAAU;IAAE,GAAG,KAAK;IAAS,GAAG;IAAY;;sBAwEpC,OACb,GAAG,SACsC;AACzC,SAAKA,SAAU,EACb,mBAAmB,KAAK,MAAM,MAAM,oBAAoB,GACzD,CAAC;AAEF,SAAKC,sBAAuB;AAI5B,OAF+B,MAAKC,2BAA4B,CAErC,SAAS,MAAKC,UAAW,EAAE;AACpD,UAAM,MAAKC,QAAS,GAAG,KAAK;AAC5B,WAAO,KAAK,MAAM,MAAM;;AAG1B,SAAKJ,SAAU,EACb,gBAAgB,KAAK,MAAM,MAAM,iBAAiB,GACnD,CAAC;AACF,QAAK,QAAQ,WAAW,MAAM,KAAK;;oCAkHA;GACnC,MAAM,yBAAyB,MAAKE,2BAA4B;AAChE,UAAO,KAAK,IAAI,GAAG,MAAKC,UAAW,GAAG,uBAAuB,OAAO;;oCAQjC;AACnC,OAAI,KAAK,sBAAsB,GAAG,EAChC,QAAO;AAGT,WADwB,KAAK,MAAM,MAAM,eAAe,MAAM,YACrC,MAAKE,WAAY,GAAG,KAAK,KAAK;;yBAuBvC,sBAAmD;GACnE,MAAM,QAAQ,qBAAqB,KAAK,MAAM,MAAM;AAEpD,UADgB,KAAK,cAAc,IAAI,MAAM,EAC7B,gBAAgB,IAAI;;qBAOlB;AAClB,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;AACxD,QAAK,cAAc,OAAO;AAC1B,SAAKL,SAAU,EACb,aAAa,OACd,CAAC;;qBAMgB;AAClB,SAAKA,SAAU,iCAAiC,CAAC;AACjD,SAAKM,eAAgB;AACrB,QAAK,cAAc,SAAS,YAAY,QAAQ,OAAO,CAAC;;AAvSxD,OAAK,MAAM,eAAe;AAC1B,OAAK,UAAU;GACb,GAAG;GACH,GAAG;GACH,cAAc,eAAe,gBAAgB,CAAC,eAAe;GAC9D;AACD,QAAKN,SAAU,KAAK,QAAQ,gBAAgB,EAAE,CAAC;AAC/C,OAAK,MAAM,iBAAiB,MAAKE,2BAA4B,CAC3D,OAAKK,kBAAmB,cAAc;AAGxC,MAAI,KAAK,IACP,kBAAiB,GAAG,uBAAuB,UAAU;AACnD,OAAI,MAAM,QAAQ,QAAQ,KAAK,IAAK;AACpC,SAAKP,SACH,MAAM,QAAQ,MAAM,MACrB;AACD,QAAK,WACH,MAAM,QAAQ,QACf;IACD;;CAWN,aAAa,aAAwD;AACnE,OAAK,MAAM,UAAU,UAAU;GAC7B,MAAM,gBAAgB;IACpB,GAAG;IACH,GAAG;IACJ;GACD,MAAM,aAAa,cAAc,eAAe,UAAU,MAAKG,UAAW;GAC1E,MAAM,SAAS,CAAC,MAAKK,YAAa,GAC9B,aACA,cAAc,cACZ,cACA,aACE,aACA;AACR,UAAO;IACL,GAAG;IACH;IACA;IACD;IACD;AACF,aAAW,oBAAoB,KAAK;;;;;CAMtC,oBAA6B;AAC3B,SAAO,CAAC,CAAC,qBAAqB,KAAK,QAAQ,SAAS,KAAK;;;;;CAM3D,kBAA0B;AACxB,SAAO,qBAAqB,KAAK,QAAQ,OAAO,KAAK;;;;;CAMvD,mBAA2B;AACzB,SAAO,qBAAqB,KAAK,QAAQ,QAAQ,KAAK;;CAmDxD,WAAW,OACT,GAAG,SACsC;AACzC,MAAI,CAAC,MAAKA,YAAa,CAAE;EAEzB,MAAM,sBAAsB,KAAK,MAAM,MAAM;EAC7C,MAAM,MAAM,KAAK,KAAK;EACtB,MAAM,iBAAiB,CAAC,GAAG,KAAK,MAAM,MAAM,gBAAgB,IAAI;AAChE,QAAKR,SAAU;GACb,aAAa;GACb;GACD,CAAC;AAEF,MAAI;GAEF,MAAM,sBAAsB,IAAI,aAAa,KAAK,IAAI;IACpD,GAAG,KAAK,QAAQ;IAChB,KAAK,GAAG,KAAK,IAAI,WAAW;IAC7B,CAAC;AACF,QAAK,cAAc,IAAI,qBAAqB,oBAAoB;GAChE,MAAM,SAAS,MAAM,oBAAoB,QAAQ,GAAG,KAAK;AACzD,SAAKO,kBAAmB,IAAI;AAC5B,SAAKP,SAAU;IACb,cAAc,KAAK,MAAM,MAAM,eAAe;IAC9C,YAAY;IACb,CAAC;AACF,QAAK,QAAQ,YAAY,QAA2B,MAAM,KAAK;WACxD,OAAO;AACd,SAAKA,SAAU,EACb,YAAY,KAAK,MAAM,MAAM,aAAa,GAC3C,CAAC;AACF,QAAK,QAAQ,UAAU,OAAgB,MAAM,KAAK;AAClD,OAAI,KAAK,QAAQ,aACf,OAAM;YAEA;AACR,QAAK,cAAc,OAAO,oBAAoB;AAC9C,SAAKA,SAAU;IACb,aAAa;IACb,aAAa,KAAK,MAAM,MAAM,cAAc;IAC7C,CAAC;AACF,QAAK,QAAQ,YAAY,MAAM,KAAK;;AAGtC,SAAO,KAAK,MAAM,MAAM;;CAG1B,mCAAkD;AAChD,MAAI,KAAK,QAAQ,eAAe,UAE9B,QAAO,KAAK,MAAM,MAAM,eAAe,QACpC,SAAS,OAAO,KAAK,KAAK,GAAG,MAAKK,WAAY,CAChD;OACI;AAGL,OAAI,KAAK,MAAM,MAAM,eAAe,WAAW,EAC7C,QAAO,EAAE;GAGX,MAAM,cADkB,KAAK,IAAI,GAAG,KAAK,MAAM,MAAM,eAAe;GAEpE,MAAM,YAAY,cAAc,MAAKA,WAAY;AAIjD,OAHY,KAAK,KAAK,GAGZ,UACR,QAAO,EAAE;AAIX,UAAO,KAAK,MAAM,MAAM,eAAe,QACpC,SAAS,QAAQ,eAAe,QAAQ,UAC1C;;;CAIL,sBAAsB,kBAAgC;AACpD,MACE,KAAK,QAAQ,eAAe,aAC5B,MAAKI,WAAY,SAAS,GAC1B;GAEA,MAAM,sBAAsB,gBADhB,KAAK,KAAK,GAC4B,MAAKJ,WAAY,GAAG;GACtE,MAAM,YAAY,iBAAiB;AACjC,UAAKJ,sBAAuB;AAC5B,UAAKS,aAAc,UAAU;MAC5B,oBAAoB;AACvB,SAAKD,WAAY,IAAI,UAAU;;;CAInC,iBAAiB,cAAmD;AAClE,eAAa,UAAU;AACvB,QAAKA,WAAY,OAAO,UAAU;;CAGpC,uBAA6B;AAC3B,QAAKA,WAAY,SAAS,cAAc,aAAa,UAAU,CAAC;AAChE,QAAKA,WAAY,OAAO;;CAG1B,8BAAoC;AAClC,QAAKT,SAAU,EACb,gBAAgB,MAAKE,2BAA4B,EAClD,CAAC;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;AA4JN,SAAgB,eACd,IACA,gBACA;AAEA,QADoB,IAAI,iBAAiB,IAAI,eAAe,CACzC"}

The AsyncRetryer class is designed to help you reliably\n * execute async operations that may fail intermittently, such as network requests or database operations,\n * by automatically retrying them according to your chosen policy.\n *\n * ## Retrying Concepts\n *\n * - **Retrying**: Automatically re-executes a failed async function up to a specified number of attempts.\n *   Useful for handling transient errors (e.g., network flakiness, rate limits, temporary server issues).\n * - **Backoff Strategies**: Controls the delay between retry attempts (default: `'exponential'`):\n *   - `'exponential'`: Wait time doubles with each attempt (1s, 2s, 4s, ...) - **DEFAULT**\n *   - `'linear'`: Wait time increases linearly (1s, 2s, 3s, ...)\n *   - `'fixed'`: Waits a constant amount of time (`baseWait`) between each attempt\n * - **Jitter**: Adds randomness to retry delays to prevent thundering herd problems (default: `0`).\n *   Set to a value between 0-1 to apply that percentage of random variation to each delay.\n * - **Max Wait**: Caps the maximum wait time between retries (default: `Infinity`).\n *   Useful for preventing exponential backoff from growing too large (e.g., cap at 30s even if exponential would be 64s).\n * - **Timeout Controls**: Set limits on execution time to prevent hanging operations:\n *   - `maxExecutionTime`: Maximum time for a single function call (default: `Infinity`)\n *   - `maxTotalExecutionTime`: Maximum time for the entire retry operation (default: `Infinity`)\n * - **Abort & Cancellation**: Supports cancellation via an internal `AbortController`. Call `abort()` to stop retries.\n *   Use `getAbortSignal()` to make your async function actually cancellable (e.g., with fetch requests).\n *\n * ## State Management\n *\n * Uses TanStack Store for fine-grained reactivity. State can be accessed via the `store.state` property.\n *\n * Available state properties:\n * - `currentAttempt`: The current retry attempt number (0 when not executing)\n * - `executionCount`: Total number of completed executions (successful or failed)\n * - `isExecuting`: Whether the retryer is currently executing the function\n * - `lastError`: The most recent error encountered during execution\n * - `lastExecutionTime`: Timestamp of the last execution completion in milliseconds\n * - `lastResult`: The result from the most recent successful execution\n * - `status`: Current execution status ('disabled' | 'idle' | 'executing' | 'retrying')\n * - `totalExecutionTime`: Total time spent executing (including retries) in milliseconds\n *\n * ## Error Handling\n *\n * The `throwOnError` option controls when errors are thrown (default: `'last'`):\n * - `'last'`: Only throws the final error after all retries are exhausted - **DEFAULT**\n * - `true`: Throws every error immediately (disables retrying)\n * - `false`: Never throws errors, returns `undefined` instead\n *\n * Callbacks for lifecycle management:\n * - `onAbort`: Called when execution is aborted (manually or due to timeouts)\n * - `onError`: Called for every error (including during retries)\n * - `onLastError`: Called only for the final error after all retries fail\n * - `onRetry`: Called before each retry attempt\n * - `onSettled`: Called after execution completes (success or failure) of each attempt\n * - `onSuccess`: Called when execution succeeds\n * - `onExecutionTimeout`: Called when a single execution attempt times out\n * - `onTotalExecutionTimeout`: Called when the total execution time times out\n *\n * ## Usage\n *\n * - Use for async operations that may fail transiently and benefit from retrying.\n * - Configure `maxAttempts`, `backoff`, `baseWait`, `maxWait`, and `jitter` to control retry behavior.\n * - Set `maxExecutionTime` and `maxTotalExecutionTime` to prevent hanging operations.\n * - Use `onAbort`, `onError`, `onLastError`, `onRetry`, `onSettled`, `onSuccess`, `onExecutionTimeout`, and `onTotalExecutionTimeout` for custom side effects.\n * - Call `abort()` to cancel ongoing execution and pending retries.\n * - Call `reset()` to reset state and cancel execution.\n * - Use `getAbortSignal()` to make your async function cancellable.\n * - Use dynamic options (functions) for `maxAttempts`, `baseWait`, and `enabled` based on retryer state.\n *\n * **Important:** This class is designed for single-use execution. Calling `execute()` multiple times\n * on the same instance will abort previous executions. For multiple calls, create a new instance\n * each time.\n *\n * @example\n * ```typescript\n * // Retry a fetch operation up to 5 times with exponential backoff, jitter, and timeouts\n * const retryer = new AsyncRetryer(async (url: string) => {\n *   const signal = retryer.getAbortSignal()\n *   return await fetch(url, { signal })\n * }, {\n *   maxAttempts: 5,\n *   backoff: 'exponential',\n *   baseWait: 1000,\n *   jitter: 0.1, // Add 10% random variation to prevent thundering herd\n *   maxExecutionTime: 5000, // Abort individual calls after 5 seconds\n *   maxTotalExecutionTime: 30000, // Abort entire operation after 30 seconds\n *   onRetry: (attempt, error) => console.log(`Retry attempt ${attempt} after error:`, error),\n *   onSuccess: (result) => console.log('Success:', result),\n *   onError: (error) => console.error('Error:', error),\n *   onLastError: (error) => console.error('All retries failed:', error),\n * })\n *\n * const result = await retryer.execute('/api/data')\n * ```\n *\n * @template TFn The async function type to be retried.\n */\nexport class AsyncRetryer<TFn extends AnyAsyncFunction> {\n  readonly store: Store<Readonly<AsyncRetryerState<TFn>>> = new Store(\n    getDefaultAsyncRetryerState<TFn>(),\n  )\n  key: string | undefined\n  options: AsyncRetryerOptions<TFn> & typeof defaultOptions\n  #abortController: AbortController | null = null\n\n  /**\n   * Creates a new AsyncRetryer instance\n   * @param fn The async function to retry\n   * @param initialOptions Configuration options for the retryer\n   */\n  constructor(\n    public fn: TFn,\n    initialOptions: AsyncRetryerOptions<TFn> = {},\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n      throwOnError:\n        initialOptions.throwOnError ??\n        (initialOptions.onError ? false : defaultOptions.throwOnError),\n    }\n    this.#setState(this.options.initialState ?? {})\n\n    if (this.key) {\n      pacerEventClient.on('d-AsyncRetryer', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(\n          event.payload.store.state as Partial<AsyncRetryerState<TFn>>,\n        )\n        this.setOptions(\n          event.payload.options as Partial<AsyncRetryerOptions<TFn>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the retryer options\n   * @param newOptions Partial options to merge with existing options\n   */\n  setOptions = (newOptions: Partial<AsyncRetryerOptions<TFn>>): void => {\n    this.options = { ...this.options, ...newOptions }\n  }\n\n  #setState = (newState: Partial<AsyncRetryerState<TFn>>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const { isExecuting, currentAttempt } = combinedState\n      return {\n        ...combinedState,\n        status: !this.#getEnabled()\n          ?

The AsyncRetryer class is designed to help you reliably\n * execute async operations that may fail intermittently, such as network requests or database operations,\n * by automatically retrying them according to your chosen policy.\n *\n * ## Retrying Concepts\n *\n * - **Retrying**: Automatically re-executes a failed async function up to a specified number of attempts.\n *   Useful for handling transient errors (e.g., network flakiness, rate limits, temporary server issues).\n * - **Backoff Strategies**: Controls the delay between retry attempts (default: `'exponential'`):\n *   - `'exponential'`: Wait time doubles with each attempt (1s, 2s, 4s, ...) - **DEFAULT**\n *   - `'linear'`: Wait time increases linearly (1s, 2s, 3s, ...)\n *   - `'fixed'`: Waits a constant amount of time (`baseWait`) between each attempt\n * - **Jitter**: Adds randomness to retry delays to prevent thundering herd problems (default: `0`).\n *   Set to a value between 0-1 to apply that percentage of random variation to each delay.\n * - **Max Wait**: Caps the maximum wait time between retries (default: `Infinity`).\n *   Useful for preventing exponential backoff from growing too large (e.g., cap at 30s even if exponential would be 64s).\n * - **Timeout Controls**: Set limits on execution time to prevent hanging operations:\n *   - `maxExecutionTime`: Maximum time for a single function call (default: `Infinity`)\n *   - `maxTotalExecutionTime`: Maximum time for the entire retry operation (default: `Infinity`)\n * - **Abort & Cancellation**: Supports cancellation via an internal `AbortController`. Call `abort()` to stop retries.\n *   Use `getAbortSignal()` to make your async function actually cancellable (e.g., with fetch requests).\n *\n * ## State Management\n *\n * Uses TanStack Store for fine-grained reactivity. State can be accessed via the `store.state` property.\n *\n * Available state properties:\n * - `currentAttempt`: The current retry attempt number (0 when not executing)\n * - `executionCount`: Total number of completed executions (successful or failed)\n * - `isExecuting`: Whether the retryer is currently executing the function\n * - `lastError`: The most recent error encountered during execution\n * - `lastExecutionTime`: Timestamp of the last execution completion in milliseconds\n * - `lastResult`: The result from the most recent successful execution\n * - `status`: Current execution status ('disabled' | 'idle' | 'executing' | 'retrying')\n * - `totalExecutionTime`: Total time spent executing (including retries) in milliseconds\n *\n * ## Error Handling\n *\n * The `throwOnError` option controls when errors are thrown (default: `'last'`):\n * - `'last'`: Only throws the final error after all retries are exhausted - **DEFAULT**\n * - `true`: Throws every error immediately (disables retrying)\n * - `false`: Never throws errors, returns `undefined` instead\n *\n * Callbacks for lifecycle management:\n * - `onAbort`: Called when execution is aborted (manually or due to timeouts)\n * - `onError`: Called for every error (including during retries)\n * - `onLastError`: Called only for the final error after all retries fail\n * - `onRetry`: Called before each retry attempt\n * - `onSettled`: Called after execution completes (success or failure) of each attempt\n * - `onSuccess`: Called when execution succeeds\n * - `onExecutionTimeout`: Called when a single execution attempt times out\n * - `onTotalExecutionTimeout`: Called when the total execution time times out\n *\n * ## Usage\n *\n * - Use for async operations that may fail transiently and benefit from retrying.\n * - Configure `maxAttempts`, `backoff`, `baseWait`, `maxWait`, and `jitter` to control retry behavior.\n * - Set `maxExecutionTime` and `maxTotalExecutionTime` to prevent hanging operations.\n * - Use `onAbort`, `onError`, `onLastError`, `onRetry`, `onSettled`, `onSuccess`, `onExecutionTimeout`, and `onTotalExecutionTimeout` for custom side effects.\n * - Call `abort()` to cancel ongoing execution and pending retries.\n * - Call `reset()` to reset state and cancel execution.\n * - Use `getAbortSignal()` to make your async function cancellable.\n * - Use dynamic options (functions) for `maxAttempts`, `baseWait`, and `enabled` based on retryer state.\n *\n * **Important:** This class is designed for single-use execution. Calling `execute()` multiple times\n * on the same instance will abort previous executions. For multiple calls, create a new instance\n * each time.\n *\n * @example\n * ```typescript\n * // Retry a fetch operation up to 5 times with exponential backoff, jitter, and timeouts\n * const retryer = new AsyncRetryer(async (url: string) => {\n *   const signal = retryer.getAbortSignal()\n *   return await fetch(url, { signal })\n * }, {\n *   maxAttempts: 5,\n *   backoff: 'exponential',\n *   baseWait: 1000,\n *   jitter: 0.1, // Add 10% random variation to prevent thundering herd\n *   maxExecutionTime: 5000, // Abort individual calls after 5 seconds\n *   maxTotalExecutionTime: 30000, // Abort entire operation after 30 seconds\n *   onRetry: (attempt, error) => console.log(`Retry attempt ${attempt} after error:`, error),\n *   onSuccess: (result) => console.log('Success:', result),\n *   onError: (error) => console.error('Error:', error),\n *   onLastError: (error) => console.error('All retries failed:', error),\n * })\n *\n * const result = await retryer.execute('/api/data')\n * ```\n *\n * @template TFn The async function type to be retried.\n */\nexport class AsyncRetryer<TFn extends AnyAsyncFunction> {\n  readonly store: Store<Readonly<AsyncRetryerState<TFn>>> = new Store(\n    getDefaultAsyncRetryerState<TFn>(),\n  )\n  key: string | undefined\n  options: AsyncRetryerOptions<TFn> & typeof defaultOptions\n  #abortController: AbortController | null = null\n\n  /**\n   * Creates a new AsyncRetryer instance\n   * @param fn The async function to retry\n   * @param initialOptions Configuration options for the retryer\n   */\n  constructor(\n    public fn: TFn,\n    initialOptions: AsyncRetryerOptions<TFn> = {},\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n      throwOnError:\n        initialOptions.throwOnError ??\n        (initialOptions.onError ? false : defaultOptions.throwOnError),\n    }\n    this.#setState(this.options.initialState ?? {})\n\n    if (this.key) {\n      pacerEventClient.on('d-AsyncRetryer', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(\n          event.payload.store.state as Partial<AsyncRetryerState<TFn>>,\n        )\n        this.setOptions(\n          event.payload.options as Partial<AsyncRetryerOptions<TFn>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the retryer options\n   * @param newOptions Partial options to merge with existing options\n   */\n  setOptions = (newOptions: Partial<AsyncRetryerOptions<TFn>>): void => {\n    this.options = { ...this.options, ...newOptions }\n  }\n\n  #setState = (newState: Partial<AsyncRetryerState<TFn>>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const { isExecuting, currentAttempt } = combinedState\n      return {\n        ...combinedState,\n        status: !this.#getEnabled()\n          ?

The AsyncRetryer class is designed to help you reliably\n * execute async operations that may fail intermittently, such as network requests or database operations,\n * by automatically retrying them according to your chosen policy.\n *\n * ## Retrying Concepts\n *\n * - **Retrying**: Automatically re-executes a failed async function up to a specified number of attempts.\n *   Useful for handling transient errors (e.g., network flakiness, rate limits, temporary server issues).\n * - **Backoff Strategies**: Controls the delay between retry attempts (default: `'exponential'`):\n *   - `'exponential'`: Wait time doubles with each attempt (1s, 2s, 4s, ...) - **DEFAULT**\n *   - `'linear'`: Wait time increases linearly (1s, 2s, 3s, ...)\n *   - `'fixed'`: Waits a constant amount of time (`baseWait`) between each attempt\n * - **Jitter**: Adds randomness to retry delays to prevent thundering herd problems (default: `0`).\n *   Set to a value between 0-1 to apply that percentage of random variation to each delay.\n * - **Max Wait**: Caps the maximum wait time between retries (default: `Infinity`).\n *   Useful for preventing exponential backoff from growing too large (e.g., cap at 30s even if exponential would be 64s).\n * - **Timeout Controls**: Set limits on execution time to prevent hanging operations:\n *   - `maxExecutionTime`: Maximum time for a single function call (default: `Infinity`)\n *   - `maxTotalExecutionTime`: Maximum time for the entire retry operation (default: `Infinity`)\n * - **Abort & Cancellation**: Supports cancellation via an internal `AbortController`. Call `abort()` to stop retries.\n *   Use `getAbortSignal()` to make your async function actually cancellable (e.g., with fetch requests).\n *\n * ## State Management\n *\n * Uses TanStack Store for fine-grained reactivity. State can be accessed via the `store.state` property.\n *\n * Available state properties:\n * - `currentAttempt`: The current retry attempt number (0 when not executing)\n * - `executionCount`: Total number of completed executions (successful or failed)\n * - `isExecuting`: Whether the retryer is currently executing the function\n * - `lastError`: The most recent error encountered during execution\n * - `lastExecutionTime`: Timestamp of the last execution completion in milliseconds\n * - `lastResult`: The result from the most recent successful execution\n * - `status`: Current execution status ('disabled' | 'idle' | 'executing' | 'retrying')\n * - `totalExecutionTime`: Total time spent executing (including retries) in milliseconds\n *\n * ## Error Handling\n *\n * The `throwOnError` option controls when errors are thrown (default: `'last'`):\n * - `'last'`: Only throws the final error after all retries are exhausted - **DEFAULT**\n * - `true`: Throws every error immediately (disables retrying)\n * - `false`: Never throws errors, returns `undefined` instead\n *\n * Callbacks for lifecycle management:\n * - `onAbort`: Called when execution is aborted (manually or due to timeouts)\n * - `onError`: Called for every error (including during retries)\n * - `onLastError`: Called only for the final error after all retries fail\n * - `onRetry`: Called before each retry attempt\n * - `onSettled`: Called after execution completes (success or failure) of each attempt\n * - `onSuccess`: Called when execution succeeds\n * - `onExecutionTimeout`: Called when a single execution attempt times out\n * - `onTotalExecutionTimeout`: Called when the total execution time times out\n *\n * ## Usage\n *\n * - Use for async operations that may fail transiently and benefit from retrying.\n * - Configure `maxAttempts`, `backoff`, `baseWait`, `maxWait`, and `jitter` to control retry behavior.\n * - Set `maxExecutionTime` and `maxTotalExecutionTime` to prevent hanging operations.\n * - Use `onAbort`, `onError`, `onLastError`, `onRetry`, `onSettled`, `onSuccess`, `onExecutionTimeout`, and `onTotalExecutionTimeout` for custom side effects.\n * - Call `abort()` to cancel ongoing execution and pending retries.\n * - Call `reset()` to reset state and cancel execution.\n * - Use `getAbortSignal()` to make your async function cancellable.\n * - Use dynamic options (functions) for `maxAttempts`, `baseWait`, and `enabled` based on retryer state.\n *\n * **Important:** This class is designed for single-use execution. Calling `execute()` multiple times\n * on the same instance will abort previous executions. For multiple calls, create a new instance\n * each time.\n *\n * @example\n * ```typescript\n * // Retry a fetch operation up to 5 times with exponential backoff, jitter, and timeouts\n * const retryer = new AsyncRetryer(async (url: string) => {\n *   const signal = retryer.getAbortSignal()\n *   return await fetch(url, { signal })\n * }, {\n *   maxAttempts: 5,\n *   backoff: 'exponential',\n *   baseWait: 1000,\n *   jitter: 0.1, // Add 10% random variation to prevent thundering herd\n *   maxExecutionTime: 5000, // Abort individual calls after 5 seconds\n *   maxTotalExecutionTime: 30000, // Abort entire operation after 30 seconds\n *   onRetry: (attempt, error) => console.log(`Retry attempt ${attempt} after error:`, error),\n *   onSuccess: (result) => console.log('Success:', result),\n *   onError: (error) => console.error('Error:', error),\n *   onLastError: (error) => console.error('All retries failed:', error),\n * })\n *\n * const result = await retryer.execute('/api/data')\n * ```\n *\n * @template TFn The async function type to be retried.\n */\nexport class AsyncRetryer<TFn extends AnyAsyncFunction> {\n  readonly store: Store<Readonly<AsyncRetryerState<TFn>>> = new Store(\n    getDefaultAsyncRetryerState<TFn>(),\n  )\n  key: string | undefined\n  options: AsyncRetryerOptions<TFn> & typeof defaultOptions\n  #abortController: AbortController | null = null\n\n  /**\n   * Creates a new AsyncRetryer instance\n   * @param fn The async function to retry\n   * @param initialOptions Configuration options for the retryer\n   */\n  constructor(\n    public fn: TFn,\n    initialOptions: AsyncRetryerOptions<TFn> = {},\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n      throwOnError:\n        initialOptions.throwOnError ??\n        (initialOptions.onError ? false : defaultOptions.throwOnError),\n    }\n    this.#setState(this.options.initialState ?? {})\n\n    if (this.key) {\n      pacerEventClient.on('d-AsyncRetryer', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(\n          event.payload.store.state as Partial<AsyncRetryerState<TFn>>,\n        )\n        this.setOptions(\n          event.payload.options as Partial<AsyncRetryerOptions<TFn>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the retryer options\n   * @param newOptions Partial options to merge with existing options\n   */\n  setOptions = (newOptions: Partial<AsyncRetryerOptions<TFn>>): void => {\n    this.options = { ...this.options, ...newOptions }\n  }\n\n  #setState = (newState: Partial<AsyncRetryerState<TFn>>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const { isExecuting, currentAttempt } = combinedState\n      return {\n        ...combinedState,\n        status: !this.#getEnabled()\n          ?

The AsyncRetryer class is designed to help you reliably\n * execute async operations that may fail intermittently, such as network requests or database operations,\n * by automatically retrying them according to your chosen policy.\n *\n * ## Retrying Concepts\n *\n * - **Retrying**: Automatically re-executes a failed async function up to a specified number of attempts.\n *   Useful for handling transient errors (e.g., network flakiness, rate limits, temporary server issues).\n * - **Backoff Strategies**: Controls the delay between retry attempts (default: `'exponential'`):\n *   - `'exponential'`: Wait time doubles with each attempt (1s, 2s, 4s, ...) - **DEFAULT**\n *   - `'linear'`: Wait time increases linearly (1s, 2s, 3s, ...)\n *   - `'fixed'`: Waits a constant amount of time (`baseWait`) between each attempt\n * - **Jitter**: Adds randomness to retry delays to prevent thundering herd problems (default: `0`).\n *   Set to a value between 0-1 to apply that percentage of random variation to each delay.\n * - **Max Wait**: Caps the maximum wait time between retries (default: `Infinity`).\n *   Useful for preventing exponential backoff from growing too large (e.g., cap at 30s even if exponential would be 64s).\n * - **Timeout Controls**: Set limits on execution time to prevent hanging operations:\n *   - `maxExecutionTime`: Maximum time for a single function call (default: `Infinity`)\n *   - `maxTotalExecutionTime`: Maximum time for the entire retry operation (default: `Infinity`)\n * - **Abort & Cancellation**: Supports cancellation via an internal `AbortController`. Call `abort()` to stop retries.\n *   Use `getAbortSignal()` to make your async function actually cancellable (e.g., with fetch requests).\n *\n * ## State Management\n *\n * Uses TanStack Store for fine-grained reactivity. State can be accessed via the `store.state` property.\n *\n * Available state properties:\n * - `currentAttempt`: The current retry attempt number (0 when not executing)\n * - `executionCount`: Total number of completed executions (successful or failed)\n * - `isExecuting`: Whether the retryer is currently executing the function\n * - `lastError`: The most recent error encountered during execution\n * - `lastExecutionTime`: Timestamp of the last execution completion in milliseconds\n * - `lastResult`: The result from the most recent successful execution\n * - `status`: Current execution status ('disabled' | 'idle' | 'executing' | 'retrying')\n * - `totalExecutionTime`: Total time spent executing (including retries) in milliseconds\n *\n * ## Error Handling\n *\n * The `throwOnError` option controls when errors are thrown (default: `'last'`):\n * - `'last'`: Only throws the final error after all retries are exhausted - **DEFAULT**\n * - `true`: Throws every error immediately (disables retrying)\n * - `false`: Never throws errors, returns `undefined` instead\n *\n * Callbacks for lifecycle management:\n * - `onAbort`: Called when execution is aborted (manually or due to timeouts)\n * - `onError`: Called for every error (including during retries)\n * - `onLastError`: Called only for the final error after all retries fail\n * - `onRetry`: Called before each retry attempt\n * - `onSettled`: Called after execution completes (success or failure) of each attempt\n * - `onSuccess`: Called when execution succeeds\n * - `onExecutionTimeout`: Called when a single execution attempt times out\n * - `onTotalExecutionTimeout`: Called when the total execution time times out\n *\n * ## Usage\n *\n * - Use for async operations that may fail transiently and benefit from retrying.\n * - Configure `maxAttempts`, `backoff`, `baseWait`, `maxWait`, and `jitter` to control retry behavior.\n * - Set `maxExecutionTime` and `maxTotalExecutionTime` to prevent hanging operations.\n * - Use `onAbort`, `onError`, `onLastError`, `onRetry`, `onSettled`, `onSuccess`, `onExecutionTimeout`, and `onTotalExecutionTimeout` for custom side effects.\n * - Call `abort()` to cancel ongoing execution and pending retries.\n * - Call `reset()` to reset state and cancel execution.\n * - Use `getAbortSignal()` to make your async function cancellable.\n * - Use dynamic options (functions) for `maxAttempts`, `baseWait`, and `enabled` based on retryer state.\n *\n * **Important:** This class is designed for single-use execution. Calling `execute()` multiple times\n * on the same instance will abort previous executions. For multiple calls, create a new instance\n * each time.\n *\n * @example\n * ```typescript\n * // Retry a fetch operation up to 5 times with exponential backoff, jitter, and timeouts\n * const retryer = new AsyncRetryer(async (url: string) => {\n *   const signal = retryer.getAbortSignal()\n *   return await fetch(url, { signal })\n * }, {\n *   maxAttempts: 5,\n *   backoff: 'exponential',\n *   baseWait: 1000,\n *   jitter: 0.1, // Add 10% random variation to prevent thundering herd\n *   maxExecutionTime: 5000, // Abort individual calls after 5 seconds\n *   maxTotalExecutionTime: 30000, // Abort entire operation after 30 seconds\n *   onRetry: (attempt, error) => console.log(`Retry attempt ${attempt} after error:`, error),\n *   onSuccess: (result) => console.log('Success:', result),\n *   onError: (error) => console.error('Error:', error),\n *   onLastError: (error) => console.error('All retries failed:', error),\n * })\n *\n * const result = await retryer.execute('/api/data')\n * ```\n *\n * @template TFn The async function type to be retried.\n */\nexport class AsyncRetryer<TFn extends AnyAsyncFunction> {\n  readonly store: Store<Readonly<AsyncRetryerState<TFn>>> = new Store(\n    getDefaultAsyncRetryerState<TFn>(),\n  )\n  key: string | undefined\n  options: AsyncRetryerOptions<TFn> & typeof defaultOptions\n  #abortController: AbortController | null = null\n\n  /**\n   * Creates a new AsyncRetryer instance\n   * @param fn The async function to retry\n   * @param initialOptions Configuration options for the retryer\n   */\n  constructor(\n    public fn: TFn,\n    initialOptions: AsyncRetryerOptions<TFn> = {},\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n      throwOnError:\n        initialOptions.throwOnError ??\n        (initialOptions.onError ? false : defaultOptions.throwOnError),\n    }\n    this.#setState(this.options.initialState ?? {})\n\n    if (this.key) {\n      pacerEventClient.on('d-AsyncRetryer', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(\n          event.payload.store.state as Partial<AsyncRetryerState<TFn>>,\n        )\n        this.setOptions(\n          event.payload.options as Partial<AsyncRetryerOptions<TFn>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the retryer options\n   * @param newOptions Partial options to merge with existing options\n   */\n  setOptions = (newOptions: Partial<AsyncRetryerOptions<TFn>>): void => {\n    this.options = { ...this.options, ...newOptions }\n  }\n\n  #setState = (newState: Partial<AsyncRetryerState<TFn>>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const { isExecuting, currentAttempt } = combinedState\n      return {\n        ...combinedState,\n        status: !this.#getEnabled()\n          ?

Returns promises that can be awaited for throttled function results\n * - Built-in retry support via AsyncRetryer integration\n * - Abort support to cancel in-flight executions\n * - Cancel support to prevent pending executions from starting\n * - Comprehensive error handling with onError callbacks and throwOnError control\n * - Detailed execution tracking (success/error/settle counts)\n * - Waits for ongoing executions to complete before scheduling the next one\n *\n * The sync Throttler is lighter weight and simpler when you don't need async features,\n * return values, or execution control.\n *\n * What is Throttling?\n * Throttling limits how often a function can be executed, allowing only one execution within a specified time window.\n * Unlike debouncing which resets the delay timer on each call, throttling ensures the function executes at a\n * regular interval regardless of how often it's called.\n *\n * This is useful for rate-limiting API calls, handling scroll/resize events, or any scenario where you want to\n * ensure a maximum execution frequency.\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and throttler instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the underlying AsyncThrottler instance\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async throttler\n * - Use `onSuccess` callback to react to successful function execution and implement custom logic\n * - Use `onError` callback to react to function execution errors and implement custom error handling\n * - Use `onSettled` callback to react to function execution completion (success or error) and implement custom logic\n * - The state includes error count, execution status, last execution time, and success/settle counts\n * - State can be accessed via `asyncThrottler.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `asyncThrottler.state`\n *\n * @example\n * ```ts\n * const throttler = new AsyncThrottler(async (value: string) => {\n *   const result = await saveToAPI(value);\n *   return result; // Return value is preserved\n * }, {\n *   wait: 1000,\n *   onError: (error) => {\n *     console.error('API call failed:', error);\n *   }\n * });\n *\n * // Will only execute once per second no matter how often called\n * // Returns the API response directly\n * const result = await throttler.maybeExecute(inputElement.value);\n * ```\n */\nexport class AsyncThrottler<TFn extends AnyAsyncFunction> {\n  readonly store: Store<Readonly<AsyncThrottlerState<TFn>>> = new Store<\n    AsyncThrottlerState<TFn>\n  >(getDefaultAsyncThrottlerState<TFn>())\n  key: string | undefined\n  options: AsyncThrottlerOptions<TFn>\n  asyncRetryers = new Map<number, AsyncRetryer<TFn>>()\n  #timeoutId: NodeJS.Timeout | null = null\n  #resolvePreviousPromise:\n    | ((value?: ReturnType<TFn> | undefined) => void)\n    | null = null\n\n  constructor(\n    public fn: TFn,\n    initialOptions: AsyncThrottlerOptions<TFn>,\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n      throwOnError: initialOptions.throwOnError ?? !initialOptions.onError,\n    }\n    this.#setState(this.options.initialState ?? {})\n\n    if (this.key) {\n      pacerEventClient.on('d-AsyncThrottler', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(\n          event.payload.store.state as Partial<AsyncThrottlerState<TFn>>,\n        )\n        this.setOptions(\n          event.payload.options as Partial<AsyncThrottlerOptions<TFn>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the async throttler options\n   */\n  setOptions = (newOptions: Partial<AsyncThrottlerOptions<TFn>>): void => {\n    this.options = { ...this.options, ...newOptions }\n\n    // End the pending state if the throttler is disabled\n    if (!this.#getEnabled()) {\n      this.cancel()\n    }\n  }\n\n  #setState = (newState: Partial<AsyncThrottlerState<TFn>>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const { isPending, isExecuting, settleCount } = combinedState\n      return {\n        ...combinedState,\n        status: !this.#getEnabled()\n          ?

Returns promises that can be awaited for throttled function results\n * - Built-in retry support via AsyncRetryer integration\n * - Abort support to cancel in-flight executions\n * - Cancel support to prevent pending executions from starting\n * - Comprehensive error handling with onError callbacks and throwOnError control\n * - Detailed execution tracking (success/error/settle counts)\n * - Waits for ongoing executions to complete before scheduling the next one\n *\n * The sync Throttler is lighter weight and simpler when you don't need async features,\n * return values, or execution control.\n *\n * What is Throttling?\n * Throttling limits how often a function can be executed, allowing only one execution within a specified time window.\n * Unlike debouncing which resets the delay timer on each call, throttling ensures the function executes at a\n * regular interval regardless of how often it's called.\n *\n * This is useful for rate-limiting API calls, handling scroll/resize events, or any scenario where you want to\n * ensure a maximum execution frequency.\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and throttler instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the underlying AsyncThrottler instance\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async throttler\n * - Use `onSuccess` callback to react to successful function execution and implement custom logic\n * - Use `onError` callback to react to function execution errors and implement custom error handling\n * - Use `onSettled` callback to react to function execution completion (success or error) and implement custom logic\n * - The state includes error count, execution status, last execution time, and success/settle counts\n * - State can be accessed via `asyncThrottler.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `asyncThrottler.state`\n *\n * @example\n * ```ts\n * const throttler = new AsyncThrottler(async (value: string) => {\n *   const result = await saveToAPI(value);\n *   return result; // Return value is preserved\n * }, {\n *   wait: 1000,\n *   onError: (error) => {\n *     console.error('API call failed:', error);\n *   }\n * });\n *\n * // Will only execute once per second no matter how often called\n * // Returns the API response directly\n * const result = await throttler.maybeExecute(inputElement.value);\n * ```\n */\nexport class AsyncThrottler<TFn extends AnyAsyncFunction> {\n  readonly store: Store<Readonly<AsyncThrottlerState<TFn>>> = new Store<\n    AsyncThrottlerState<TFn>\n  >(getDefaultAsyncThrottlerState<TFn>())\n  key: string | undefined\n  options: AsyncThrottlerOptions<TFn>\n  asyncRetryers = new Map<number, AsyncRetryer<TFn>>()\n  #timeoutId: ReturnType<typeof setTimeout> | null = null\n  #resolvePreviousPromise:\n    | ((value?: ReturnType<TFn> | undefined) => void)\n    | null = null\n\n  constructor(\n    public fn: TFn,\n    initialOptions: AsyncThrottlerOptions<TFn>,\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n      throwOnError: initialOptions.throwOnError ?? !initialOptions.onError,\n    }\n    this.#setState(this.options.initialState ?? {})\n\n    if (this.key) {\n      pacerEventClient.on('d-AsyncThrottler', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(\n          event.payload.store.state as Partial<AsyncThrottlerState<TFn>>,\n        )\n        this.setOptions(\n          event.payload.options as Partial<AsyncThrottlerOptions<TFn>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the async throttler options\n   */\n  setOptions = (newOptions: Partial<AsyncThrottlerOptions<TFn>>): void => {\n    this.options = { ...this.options, ...newOptions }\n\n    // End the pending state if the throttler is disabled\n    if (!this.#getEnabled()) {\n      this.cancel()\n    }\n  }\n\n  #setState = (newState: Partial<AsyncThrottlerState<TFn>>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const { isPending, isExecuting, settleCount } = combinedState\n      return {\n        ...combinedState,\n        status: !this.#getEnabled()\n          ?

at most once per wait period, even if called multiple times.\n * If called while executing, it will wait until execution completes before scheduling the next call.\n *\n * Async vs Sync Versions:\n * The async version provides advanced features over the sync throttle function:\n * - Returns promises that can be awaited for throttled function results\n * - Built-in retry support via AsyncRetryer integration\n * - Abort support to cancel in-flight executions\n * - Cancel support to prevent pending executions from starting\n * - Comprehensive error handling with onError callbacks and throwOnError control\n * - Detailed execution tracking (success/error/settle counts)\n * - Waits for ongoing executions to complete before scheduling the next one\n *\n * The sync throttle function is lighter weight and simpler when you don't need async features,\n * return values, or execution control.\n *\n * What is Throttling?\n * Throttling limits how often a function can be executed, allowing only one execution within a specified time window.\n * Unlike debouncing which resets the delay timer on each call, throttling ensures the function executes at a\n * regular interval regardless of how often it's called.\n *\n * Configuration Options:\n * - `wait`: Time window in milliseconds during which the function can only execute once (required)\n * - `leading`: Execute immediately when called (default: true)\n * - `trailing`: Execute on the trailing edge of the wait period (default: true)\n * - `enabled`: Whether the throttler is enabled (default: true)\n * - `asyncRetryerOptions`: Configure retry behavior for executions\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and throttler instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the underlying AsyncThrottler instance\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async throttler\n * - Use `onSuccess` callback to react to successful function execution and implement custom logic\n * - Use `onError` callback to react to function execution errors and implement custom error handling\n * - Use `onSettled` callback to react to function execution completion (success or error) and implement custom logic\n * - The state includes error count, execution status, last execution time, and success/settle counts\n * - State can be accessed via the underlying AsyncThrottler instance's `store.state` property\n * - When using framework adapters (React/Solid), state is accessed from the hook's state property\n *\n * @example\n * ```ts\n * const throttled = asyncThrottle(async (value: string) => {\n *   const result = await saveToAPI(value);\n *   return result; // Return value is preserved\n * }, {\n *   wait: 1000,\n *   onError: (error) => {\n *     console.error('API call failed:', error);\n *   }\n * });\n *\n * // This will execute at most once per second\n * // Returns the API response directly\n * const result = await throttled(inputElement.value);\n * ```\n */\nexport function asyncThrottle<TFn extends AnyAsyncFunction>(\n  fn: TFn,\n  initialOptions: AsyncThrottlerOptions<TFn>,\n) {\n  const asyncThrottler = new

at most once per wait period, even if called multiple times.\n * If called while executing, it will wait until execution completes before scheduling the next call.\n *\n * Async vs Sync Versions:\n * The async version provides advanced features over the sync throttle function:\n * - Returns promises that can be awaited for throttled function results\n * - Built-in retry support via AsyncRetryer integration\n * - Abort support to cancel in-flight executions\n * - Cancel support to prevent pending executions from starting\n * - Comprehensive error handling with onError callbacks and throwOnError control\n * - Detailed execution tracking (success/error/settle counts)\n * - Waits for ongoing executions to complete before scheduling the next one\n *\n * The sync throttle function is lighter weight and simpler when you don't need async features,\n * return values, or execution control.\n *\n * What is Throttling?\n * Throttling limits how often a function can be executed, allowing only one execution within a specified time window.\n * Unlike debouncing which resets the delay timer on each call, throttling ensures the function executes at a\n * regular interval regardless of how often it's called.\n *\n * Configuration Options:\n * - `wait`: Time window in milliseconds during which the function can only execute once (required)\n * - `leading`: Execute immediately when called (default: true)\n * - `trailing`: Execute on the trailing edge of the wait period (default: true)\n * - `enabled`: Whether the throttler is enabled (default: true)\n * - `asyncRetryerOptions`: Configure retry behavior for executions\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and throttler instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the underlying AsyncThrottler instance\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async throttler\n * - Use `onSuccess` callback to react to successful function execution and implement custom logic\n * - Use `onError` callback to react to function execution errors and implement custom error handling\n * - Use `onSettled` callback to react to function execution completion (success or error) and implement custom logic\n * - The state includes error count, execution status, last execution time, and success/settle counts\n * - State can be accessed via the underlying AsyncThrottler instance's `store.state` property\n * - When using framework adapters (React/Solid), state is accessed from the hook's state property\n *\n * @example\n * ```ts\n * const throttled = asyncThrottle(async (value: string) => {\n *   const result = await saveToAPI(value);\n *   return result; // Return value is preserved\n * }, {\n *   wait: 1000,\n *   onError: (error) => {\n *     console.error('API call failed:', error);\n *   }\n * });\n *\n * // This will execute at most once per second\n * // Returns the API response directly\n * const result = await throttled(inputElement.value);\n * ```\n */\nexport function asyncThrottle<TFn extends AnyAsyncFunction>(\n  fn: TFn,\n  initialOptions: AsyncThrottlerOptions<TFn>,\n) {\n  const asyncThrottler = new

Returns promises that can be awaited for throttled function results\n * - Built-in retry support via AsyncRetryer integration\n * - Abort support to cancel in-flight executions\n * - Cancel support to prevent pending executions from starting\n * - Comprehensive error handling with onError callbacks and throwOnError control\n * - Detailed execution tracking (success/error/settle counts)\n * - Waits for ongoing executions to complete before scheduling the next one\n *\n * The sync Throttler is lighter weight and simpler when you don't need async features,\n * return values, or execution control.\n *\n * What is Throttling?\n * Throttling limits how often a function can be executed, allowing only one execution within a specified time window.\n * Unlike debouncing which resets the delay timer on each call, throttling ensures the function executes at a\n * regular interval regardless of how often it's called.\n *\n * This is useful for rate-limiting API calls, handling scroll/resize events, or any scenario where you want to\n * ensure a maximum execution frequency.\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and throttler instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the underlying AsyncThrottler instance\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async throttler\n * - Use `onSuccess` callback to react to successful function execution and implement custom logic\n * - Use `onError` callback to react to function execution errors and implement custom error handling\n * - Use `onSettled` callback to react to function execution completion (success or error) and implement custom logic\n * - The state includes error count, execution status, last execution time, and success/settle counts\n * - State can be accessed via `asyncThrottler.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `asyncThrottler.state`\n *\n * @example\n * ```ts\n * const throttler = new AsyncThrottler(async (value: string) => {\n *   const result = await saveToAPI(value);\n *   return result; // Return value is preserved\n * }, {\n *   wait: 1000,\n *   onError: (error) => {\n *     console.error('API call failed:', error);\n *   }\n * });\n *\n * // Will only execute once per second no matter how often called\n * // Returns the API response directly\n * const result = await throttler.maybeExecute(inputElement.value);\n * ```\n */\nexport class AsyncThrottler<TFn extends AnyAsyncFunction> {\n  readonly store: Store<Readonly<AsyncThrottlerState<TFn>>> = new Store<\n    AsyncThrottlerState<TFn>\n  >(getDefaultAsyncThrottlerState<TFn>())\n  key: string | undefined\n  options: AsyncThrottlerOptions<TFn>\n  asyncRetryers = new Map<number, AsyncRetryer<TFn>>()\n  #timeoutId: ReturnType<typeof setTimeout> | null = null\n  #resolvePreviousPromise:\n    | ((value?: ReturnType<TFn> | undefined) => void)\n    | null = null\n\n  constructor(\n    public fn: TFn,\n    initialOptions: AsyncThrottlerOptions<TFn>,\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n      throwOnError: initialOptions.throwOnError ?? !initialOptions.onError,\n    }\n    this.#setState(this.options.initialState ?? {})\n\n    if (this.key) {\n      pacerEventClient.on('d-AsyncThrottler', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(\n          event.payload.store.state as Partial<AsyncThrottlerState<TFn>>,\n        )\n        this.setOptions(\n          event.payload.options as Partial<AsyncThrottlerOptions<TFn>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the async throttler options\n   */\n  setOptions = (newOptions: Partial<AsyncThrottlerOptions<TFn>>): void => {\n    this.options = { ...this.options, ...newOptions }\n\n    // End the pending state if the throttler is disabled\n    if (!this.#getEnabled()) {\n      this.cancel()\n    }\n  }\n\n  #setState = (newState: Partial<AsyncThrottlerState<TFn>>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const { isPending, isExecuting, settleCount } = combinedState\n      return {\n        ...combinedState,\n        status: !this.#getEnabled()\n          ?

at most once per wait period, even if called multiple times.\n * If called while executing, it will wait until execution completes before scheduling the next call.\n *\n * Async vs Sync Versions:\n * The async version provides advanced features over the sync throttle function:\n * - Returns promises that can be awaited for throttled function results\n * - Built-in retry support via AsyncRetryer integration\n * - Abort support to cancel in-flight executions\n * - Cancel support to prevent pending executions from starting\n * - Comprehensive error handling with onError callbacks and throwOnError control\n * - Detailed execution tracking (success/error/settle counts)\n * - Waits for ongoing executions to complete before scheduling the next one\n *\n * The sync throttle function is lighter weight and simpler when you don't need async features,\n * return values, or execution control.\n *\n * What is Throttling?\n * Throttling limits how often a function can be executed, allowing only one execution within a specified time window.\n * Unlike debouncing which resets the delay timer on each call, throttling ensures the function executes at a\n * regular interval regardless of how often it's called.\n *\n * Configuration Options:\n * - `wait`: Time window in milliseconds during which the function can only execute once (required)\n * - `leading`: Execute immediately when called (default: true)\n * - `trailing`: Execute on the trailing edge of the wait period (default: true)\n * - `enabled`: Whether the throttler is enabled (default: true)\n * - `asyncRetryerOptions`: Configure retry behavior for executions\n *\n * Error Handling:\n * - If an `onError` handler is provided, it will be called with the error and throttler instance\n * - If `throwOnError` is true (default when no onError handler is provided), the error will be thrown\n * - If `throwOnError` is false (default when onError handler is provided), the error will be swallowed\n * - Both onError and throwOnError can be used together - the handler will be called before any error is thrown\n * - The error state can be checked using the underlying AsyncThrottler instance\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the async throttler\n * - Use `onSuccess` callback to react to successful function execution and implement custom logic\n * - Use `onError` callback to react to function execution errors and implement custom error handling\n * - Use `onSettled` callback to react to function execution completion (success or error) and implement custom logic\n * - The state includes error count, execution status, last execution time, and success/settle counts\n * - State can be accessed via the underlying AsyncThrottler instance's `store.state` property\n * - When using framework adapters (React/Solid), state is accessed from the hook's state property\n *\n * @example\n * ```ts\n * const throttled = asyncThrottle(async (value: string) => {\n *   const result = await saveToAPI(value);\n *   return result; // Return value is preserved\n * }, {\n *   wait: 1000,\n *   onError: (error) => {\n *     console.error('API call failed:', error);\n *   }\n * });\n *\n * // This will execute at most once per second\n * // Returns the API response directly\n * const result = await throttled(inputElement.value);\n * ```\n */\nexport function asyncThrottle<TFn extends AnyAsyncFunction>(\n  fn: TFn,\n  initialOptions: AsyncThrottlerOptions<TFn>,\n) {\n  const asyncThrottler = new

Maximum batch size (number of items per batch)\n * - Time-based batching (process after X milliseconds)\n * - Custom batch processing logic via getShouldExecute\n * - Event callbacks for monitoring batch operations\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the batcher\n * - Use `onExecute` callback to react to batch execution and implement custom logic\n * - Use `onItemsChange` callback to react to items being added or removed from the batcher\n * - The state includes batch execution count, total items processed, items, and running status\n * - State can be accessed via `batcher.store.state` when using the class directly\n * -

upgrade to AsyncBatcher when you need promises, retry support, abort/cancel capabilities, or advanced error handling.\n *\n * The Batcher provides a flexible way to implement batching with configurable:\n * - Maximum batch size (number of items per batch)\n * - Time-based batching (process after X milliseconds)\n * - Custom batch processing logic via getShouldExecute\n * - Event callbacks for monitoring batch operations\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the batcher\n * - Use `onExecute` callback to react to batch execution and implement custom logic\n * - Use `onItemsChange` callback to react to items being added or removed from the batcher\n * - The state includes batch execution count, total items processed, items, and running status\n * - State can be accessed via `batcher.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `batcher.state`\n *\n * @example\n * ```ts\n * const batcher = new Batcher<number>(\n *   (items) => console.log('Processing batch:', items),\n *   {\n *     maxSize: 5,\n *     wait: 2000,\n *     onExecute: (batch, batcher) => console.log('Batch executed:', batch)\n *   }\n * );\n *\n * batcher.addItem(1);\n * batcher.addItem(2);\n * // After 2 seconds or when 5 items are added, whichever comes first,\n * // the batch will be processed\n * // batcher.flush() // manually trigger a batch\n * ```\n */\nexport class Batcher<TValue> {\n  readonly store: Store<Readonly<BatcherState<TValue>>> = new Store(\n    getDefaultBatcherState<TValue>(),\n  )\n  key: string | undefined\n  options: BatcherOptionsWithOptionalCallbacks<TValue>\n  #timeoutId: NodeJS.Timeout | null = null\n\n  constructor(\n    public fn: (items: Array<TValue>) => void,\n    initialOptions: BatcherOptions<TValue>,\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n    }\n    this.#setState(this.options.initialState ?? {})\n\n    if (this.key) {\n      pacerEventClient.on('d-Batcher', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(\n          event.payload.store.state as Partial<BatcherState<TValue>>,\n        )\n        this.setOptions(\n          event.payload.options as Partial<BatcherOptions<TValue>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the batcher options\n   */\n  setOptions = (newOptions: Partial<BatcherOptions<TValue>>): void => {\n    this.options = { ...this.options, ...newOptions }\n  }\n\n  #setState = (newState: Partial<BatcherState<TValue>>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const { isPending, items } = combinedState\n      const size = items.length\n      const isEmpty = size === 0\n      return {\n        ...combinedState,\n        isEmpty,\n        size,\n        status: isPending ?

upgrade to AsyncQueuer when you need promises, retry support, abort capabilities, concurrent execution, or advanced error handling.\n *\n * Features:\n * - Automatic or manual processing of items\n * - FIFO (First In First Out), LIFO (Last In First Out), or double-ended queue behavior\n * - Priority-based ordering when getPriority is provided\n * - Item expiration and removal of stale items\n * - Callbacks for queue state changes, execution, rejection, and expiration\n *\n * Running behavior:\n * - `start()`: Begins automatically processing items in the queue (defaults to isRunning)\n * - `stop()`: Pauses processing but maintains queue state\n * - `wait`: Configurable delay between processing items\n * - `onItemsChange`/`onExecute`: Callbacks for monitoring queue state\n *\n * Manual processing is also supported when automatic processing is disabled:\n * - `execute()`: Processes the next item using the provided function\n * - `getNextItem()`: Removes and returns the next item without processing\n *\n * Queue behavior defaults to FIFO:\n * - `addItem(item)`: Adds to the back of the queue\n * - Items processed from the front of the queue\n *\n * Priority queue:\n * - Provide a `getPriority` function; higher values are processed first\n *\n * Stack (LIFO):\n * - `addItem(item, 'back')`: Adds to the back\n * - `getNextItem('back')`: Removes from the back\n *\n * Double-ended queue:\n * - `addItem(item, position)`: Adds to specified position ('front'/'back')\n * - `getNextItem(position)`: Removes from specified position\n *\n * Item expiration:\n * - `expirationDuration`: Maximum time items can stay in the queue\n * - `getIsExpired`: Function to override default expiration\n * - `onExpire`: Callback for expired items\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the queuer\n * - Use `onExecute` callback to react to item execution and implement custom logic\n * - Use `onItemsChange` callback to react to items being added or removed from the queue\n * - Use `onExpire` callback to react to items expiring and implement custom logic\n * - Use `onReject` callback to react to items being rejected when the queue is full\n * - The state includes execution count, expiration count, rejection count, and isRunning status\n * - State can be accessed via `queuer.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `queuer.state`\n *\n * Example usage:\n * ```ts\n * // Auto-processing queue with wait time\n * const autoQueue = new Queuer<number>((n) => console.log(n), {\n *   started: true, // Begin processing immediately\n *   wait: 1000, // Wait 1s between items\n *   onExecute: (item, queuer) => console.log(`Processed ${item}`)\n * });\n * autoQueue.addItem(1); // Will process after 1s\n * autoQueue.addItem(2); // Will process 1s after first item\n *\n * // Manual processing queue\n * const manualQueue = new Queuer<number>((n) => console.log(n), {\n *   started: false\n * });\n * manualQueue.addItem(1); // [1]\n * manualQueue.addItem(2); // [1, 2]\n * manualQueue.execute(); // logs 1, queue is [2]\n * manualQueue.getNextItem(); // returns 2, queue is empty\n * ```\n */\nexport class Queuer<TValue> {\n  readonly store: Store<Readonly<QueuerState<TValue>>> = new Store(\n    getDefaultQueuerState<TValue>(),\n  )\n  key: string | undefined\n  options: QueuerOptions<TValue>\n  #timeoutId: NodeJS.Timeout | null = null\n\n  constructor(\n    public fn: (item: TValue) => void,\n    initialOptions: QueuerOptions<TValue> = {},\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n    }\n    const isInitiallyRunning =\n      this.options.initialState?.isRunning ?? this.options.started ?? true\n    this.#setState({\n      ...this.options.initialState,\n      isRunning: isInitiallyRunning,\n    })\n\n    if (this.options.initialState?.items) {\n      if (this.store.state.isRunning) {\n        this.#tick()\n      }\n    } else {\n      for (let i = 0; i < (this.options.initialItems?.length ?? 0); i++) {\n        const item = this.options.initialItems![i]!\n        const isLast = i === (this.options.initialItems?.length ?? 0) -

upgrade to AsyncQueuer when you need promises, retry support, abort capabilities, concurrent execution, or advanced error handling.\n *\n * Features:\n * - Automatic or manual processing of items\n * - FIFO (First In First Out), LIFO (Last In First Out), or double-ended queue behavior\n * - Priority-based ordering when getPriority is provided\n * - Item expiration and removal of stale items\n * - Callbacks for queue state changes, execution, rejection, and expiration\n *\n * Running behavior:\n * - `start()`: Begins automatically processing items in the queue (defaults to isRunning)\n * - `stop()`: Pauses processing but maintains queue state\n * - `wait`: Configurable delay between processing items\n * - `onItemsChange`/`onExecute`: Callbacks for monitoring queue state\n *\n * Manual processing is also supported when automatic processing is disabled:\n * - `execute()`: Processes the next item using the provided function\n * - `getNextItem()`: Removes and returns the next item without processing\n *\n * Queue behavior defaults to FIFO:\n * - `addItem(item)`: Adds to the back of the queue\n * - Items processed from the front of the queue\n *\n * Priority queue:\n * - Provide a `getPriority` function; higher values are processed first\n *\n * Stack (LIFO):\n * - `addItem(item, 'back')`: Adds to the back\n * - `getNextItem('back')`: Removes from the back\n *\n * Double-ended queue:\n * - `addItem(item, position)`: Adds to specified position ('front'/'back')\n * - `getNextItem(position)`: Removes from specified position\n *\n * Item expiration:\n * - `expirationDuration`: Maximum time items can stay in the queue\n * - `getIsExpired`: Function to override default expiration\n * - `onExpire`: Callback for expired items\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the queuer\n * - Use `onExecute` callback to react to item execution and implement custom logic\n * - Use `onItemsChange` callback to react to items being added or removed from the queue\n * - Use `onExpire` callback to react to items expiring and implement custom logic\n * - Use `onReject` callback to react to items being rejected when the queue is full\n * - The state includes execution count, expiration count, rejection count, and isRunning status\n * - State can be accessed via `queuer.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `queuer.state`\n *\n * Example usage:\n * ```ts\n * // Auto-processing queue with wait time\n * const autoQueue = new Queuer<number>((n) => console.log(n), {\n *   started: true, // Begin processing immediately\n *   wait: 1000, // Wait 1s between items\n *   onExecute: (item, queuer) => console.log(`Processed ${item}`)\n * });\n * autoQueue.addItem(1); // Will process after 1s\n * autoQueue.addItem(2); // Will process 1s after first item\n *\n * // Manual processing queue\n * const manualQueue = new Queuer<number>((n) => console.log(n), {\n *   started: false\n * });\n * manualQueue.addItem(1); // [1]\n * manualQueue.addItem(2); // [1, 2]\n * manualQueue.execute(); // logs 1, queue is [2]\n * manualQueue.getNextItem(); // returns 2, queue is empty\n * ```\n */\nexport class Queuer<TValue> {\n  readonly store: Store<Readonly<QueuerState<TValue>>> = new Store(\n    getDefaultQueuerState<TValue>(),\n  )\n  key: string | undefined\n  options: QueuerOptions<TValue>\n  #timeoutId: NodeJS.Timeout | null = null\n\n  constructor(\n    public fn: (item: TValue) => void,\n    initialOptions: QueuerOptions<TValue> = {},\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n    }\n    const isInitiallyRunning =\n      this.options.initialState?.isRunning ?? this.options.started ?? true\n    this.#setState({\n      ...this.options.initialState,\n      isRunning: isInitiallyRunning,\n    })\n\n    if (this.options.initialState?.items) {\n      if (this.store.state.isRunning) {\n        this.#tick()\n      }\n    } else {\n      for (let i = 0; i < (this.options.initialItems?.length ?? 0); i++) {\n        const item = this.options.initialItems![i]!\n        const isLast = i === (this.options.initialItems?.length ?? 0) -

management\n * - Use `initialState` to provide initial state values when creating the queuer\n * - Use `onExecute` callback to react to item execution and implement custom logic\n * - Use `onItemsChange` callback to react to items being added or removed from the queue\n * - Use `onExpire` callback to react to items expiring and implement custom logic\n * - Use `onReject` callback to react to items being rejected when the queue is full\n * - The state includes execution count, expiration count, rejection count, and isRunning status\n * - State can be accessed via the underlying Queuer instance's `store.state` property\n * - When using framework adapters (React/Solid), state is accessed from the hook's state property\n *\n * Example usage:\n * ```ts\n * // Basic sequential processing\n * const processItems = queue<number>((n) => console.log(n), {\n *   wait: 1000,\n *   onItemsChange: (queuer) => console.log(queuer.peekAllItems())\n * });\n * processItems(1); // Logs: 1\n * processItems(2); // Logs: 2 after 1 completes\n *\n * // Priority queue\n * const processPriority = queue<number>((n) => console.log(n), {\n *   getPriority: n => n // Higher numbers processed

upgrade to AsyncQueuer when you need promises, retry support, abort capabilities, concurrent execution, or advanced error handling.\n *\n * Features:\n * - Automatic or manual processing of items\n * - FIFO (First In First Out), LIFO (Last In First Out), or double-ended queue behavior\n * - Priority-based ordering when getPriority is provided\n * - Item expiration and removal of stale items\n * - Callbacks for queue state changes, execution, rejection, and expiration\n *\n * Running behavior:\n * - `start()`: Begins automatically processing items in the queue (defaults to isRunning)\n * - `stop()`: Pauses processing but maintains queue state\n * - `wait`: Configurable delay between processing items\n * - `onItemsChange`/`onExecute`: Callbacks for monitoring queue state\n *\n * Manual processing is also supported when automatic processing is disabled:\n * - `execute()`: Processes the next item using the provided function\n * - `getNextItem()`: Removes and returns the next item without processing\n *\n * Queue behavior defaults to FIFO:\n * - `addItem(item)`: Adds to the back of the queue\n * - Items processed from the front of the queue\n *\n * Priority queue:\n * - Provide a `getPriority` function; higher values are processed first\n *\n * Stack (LIFO):\n * - `addItem(item, 'back')`: Adds to the back\n * - `getNextItem('back')`: Removes from the back\n *\n * Double-ended queue:\n * - `addItem(item, position)`: Adds to specified position ('front'/'back')\n * - `getNextItem(position)`: Removes from specified position\n *\n * Item expiration:\n * - `expirationDuration`: Maximum time items can stay in the queue\n * - `getIsExpired`: Function to override default expiration\n * - `onExpire`: Callback for expired items\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the queuer\n * - Use `onExecute` callback to react to item execution and implement custom logic\n * - Use `onItemsChange` callback to react to items being added or removed from the queue\n * - Use `onExpire` callback to react to items expiring and implement custom logic\n * - Use `onReject` callback to react to items being rejected when the queue is full\n * - The state includes execution count, expiration count, rejection count, and isRunning status\n * - State can be accessed via `queuer.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `queuer.state`\n *\n * Example usage:\n * ```ts\n * // Auto-processing queue with wait time\n * const autoQueue = new Queuer<number>((n) => console.log(n), {\n *   started: true, // Begin processing immediately\n *   wait: 1000, // Wait 1s between items\n *   onExecute: (item, queuer) => console.log(`Processed ${item}`)\n * });\n * autoQueue.addItem(1); // Will process after 1s\n * autoQueue.addItem(2); // Will process 1s after first item\n *\n * // Manual processing queue\n * const manualQueue = new Queuer<number>((n) => console.log(n), {\n *   started: false\n * });\n * manualQueue.addItem(1); // [1]\n * manualQueue.addItem(2); // [1, 2]\n * manualQueue.execute(); // logs 1, queue is [2]\n * manualQueue.getNextItem(); // returns 2, queue is empty\n * ```\n */\nexport class Queuer<TValue> {\n  readonly store: Store<Readonly<QueuerState<TValue>>> = new Store(\n    getDefaultQueuerState<TValue>(),\n  )\n  key: string | undefined\n  options: QueuerOptions<TValue>\n  #timeoutId: ReturnType<typeof setTimeout> | null = null\n\n  constructor(\n    public fn: (item: TValue) => void,\n    initialOptions: QueuerOptions<TValue> = {},\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n    }\n    const isInitiallyRunning =\n      this.options.initialState?.isRunning ?? this.options.started ?? true\n    this.#setState({\n      ...this.options.initialState,\n      isRunning: isInitiallyRunning,\n    })\n\n    if (this.options.initialState?.items) {\n      if (this.store.state.isRunning) {\n        this.#tick()\n      }\n    } else {\n      for (let i = 0; i < (this.options.initialItems?.length ?? 0); i++) {\n        const item = this.options.initialItems![i]!\n        const isLast = i === (this.options.initialItems?.length ?? 0) -

This can lead to \"bursty\" behavior where\n * all executions happen immediately, followed by a complete block.\n * This synchronous version is lighter weight and often all you need - upgrade to AsyncRateLimiter when you need promises, retry support, abort capabilities, or advanced error handling.\n *\n * The rate limiter supports two types of windows:\n * - 'fixed': A strict window that resets after the window period. All executions within the window count\n *   towards the limit, and the window resets completely after the period.\n * - 'sliding': A rolling window that allows executions as old ones expire. This provides a more\n *   consistent rate of execution over time.\n *\n * For smoother execution patterns, consider using:\n * - Throttling: Ensures consistent spacing between executions (e.g. max once per 200ms)\n * - Debouncing: Waits for a pause in calls before executing (e.g. after 500ms of no calls)\n *\n * Rate limiting is best used for hard API limits or resource constraints. For UI updates or\n * smoothing out frequent events, throttling or debouncing usually provide better user experience.\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the rate limiter\n * - Use `onExecute` callback to react to function execution and implement custom logic\n * - Use `onReject` callback to react to executions being rejected when rate limit is exceeded\n * - The state includes execution count, execution times, and rejection count\n * - State can be accessed via `rateLimiter.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `rateLimiter.state`\n *\n * @example\n * ```ts\n * const rateLimiter = new RateLimiter(\n *   (id: string) => api.getData(id),\n *   {\n *     limit: 5,\n *     window: 1000,\n *     windowType: 'sliding',\n *   }\n * );\n *\n * // Will execute immediately until limit reached, then block\n * rateLimiter.maybeExecute('123');\n * ```\n */\nexport class RateLimiter<TFn extends AnyFunction> {\n  readonly store: Store<Readonly<RateLimiterState>> =\n    new Store<RateLimiterState>(getDefaultRateLimiterState())\n  key: string | undefined\n  options: RateLimiterOptions<TFn>\n  #timeoutIds: Set<NodeJS.Timeout> = new Set()\n\n  constructor(\n    public fn: TFn,\n    initialOptions: RateLimiterOptions<TFn>,\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n    }\n    this.#setState(this.options.initialState ?? {})\n    for (const executionTime of this.#getExecutionTimesInWindow()) {\n      this.#setCleanupTimeout(executionTime)\n    }\n\n    if (this.key) {\n      pacerEventClient.on('d-RateLimiter', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(event.payload.store.state as Partial<RateLimiterState>)\n        this.setOptions(\n          event.payload.options as Partial<RateLimiterOptions<TFn>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the rate limiter options\n   */\n  setOptions = (newOptions: Partial<RateLimiterOptions<TFn>>): void => {\n    this.options = { ...this.options, ...newOptions }\n  }\n\n  #setState = (newState: Partial<RateLimiterState>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const isExceeded = combinedState.executionTimes.length >= this.#getLimit()\n      const status = !this.#getEnabled()\n        ?

This can lead to \"bursty\" behavior where\n * all executions happen immediately, followed by a complete block.\n * This synchronous version is lighter weight and often all you need - upgrade to AsyncRateLimiter when you need promises, retry support, abort capabilities, or advanced error handling.\n *\n * The rate limiter supports two types of windows:\n * - 'fixed': A strict window that resets after the window period. All executions within the window count\n *   towards the limit, and the window resets completely after the period.\n * - 'sliding': A rolling window that allows executions as old ones expire. This provides a more\n *   consistent rate of execution over time.\n *\n * For smoother execution patterns, consider using:\n * - Throttling: Ensures consistent spacing between executions (e.g. max once per 200ms)\n * - Debouncing: Waits for a pause in calls before executing (e.g. after 500ms of no calls)\n *\n * Rate limiting is best used for hard API limits or resource constraints. For UI updates or\n * smoothing out frequent events, throttling or debouncing usually provide better user experience.\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the rate limiter\n * - Use `onExecute` callback to react to function execution and implement custom logic\n * - Use `onReject` callback to react to executions being rejected when rate limit is exceeded\n * - The state includes execution count, execution times, and rejection count\n * - State can be accessed via `rateLimiter.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `rateLimiter.state`\n *\n * @example\n * ```ts\n * const rateLimiter = new RateLimiter(\n *   (id: string) => api.getData(id),\n *   {\n *     limit: 5,\n *     window: 1000,\n *     windowType: 'sliding',\n *   }\n * );\n *\n * // Will execute immediately until limit reached, then block\n * rateLimiter.maybeExecute('123');\n * ```\n */\nexport class RateLimiter<TFn extends AnyFunction> {\n  readonly store: Store<Readonly<RateLimiterState>> =\n    new Store<RateLimiterState>(getDefaultRateLimiterState())\n  key: string | undefined\n  options: RateLimiterOptions<TFn>\n  #timeoutIds: Set<ReturnType<typeof setTimeout>> = new Set()\n\n  constructor(\n    public fn: TFn,\n    initialOptions: RateLimiterOptions<TFn>,\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n    }\n    this.#setState(this.options.initialState ?? {})\n    for (const executionTime of this.#getExecutionTimesInWindow()) {\n      this.#setCleanupTimeout(executionTime)\n    }\n\n    if (this.key) {\n      pacerEventClient.on('d-RateLimiter', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(event.payload.store.state as Partial<RateLimiterState>)\n        this.setOptions(\n          event.payload.options as Partial<RateLimiterOptions<TFn>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the rate limiter options\n   */\n  setOptions = (newOptions: Partial<RateLimiterOptions<TFn>>): void => {\n    this.options = { ...this.options, ...newOptions }\n  }\n\n  #setState = (newState: Partial<RateLimiterState>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const isExceeded = combinedState.executionTimes.length >= this.#getLimit()\n      const status = !this.#getEnabled()\n        ?

This can lead to \"bursty\" behavior where\n * all executions happen immediately, followed by a complete block.\n * This synchronous version is lighter weight and often all you need - upgrade to AsyncRateLimiter when you need promises, retry support, abort capabilities, or advanced error handling.\n *\n * The rate limiter supports two types of windows:\n * - 'fixed': A strict window that resets after the window period. All executions within the window count\n *   towards the limit, and the window resets completely after the period.\n * - 'sliding': A rolling window that allows executions as old ones expire. This provides a more\n *   consistent rate of execution over time.\n *\n * For smoother execution patterns, consider using:\n * - Throttling: Ensures consistent spacing between executions (e.g. max once per 200ms)\n * - Debouncing: Waits for a pause in calls before executing (e.g. after 500ms of no calls)\n *\n * Rate limiting is best used for hard API limits or resource constraints. For UI updates or\n * smoothing out frequent events, throttling or debouncing usually provide better user experience.\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the rate limiter\n * - Use `onExecute` callback to react to function execution and implement custom logic\n * - Use `onReject` callback to react to executions being rejected when rate limit is exceeded\n * - The state includes execution count, execution times, and rejection count\n * - State can be accessed via `rateLimiter.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `rateLimiter.state`\n *\n * @example\n * ```ts\n * const rateLimiter = new RateLimiter(\n *   (id: string) => api.getData(id),\n *   {\n *     limit: 5,\n *     window: 1000,\n *     windowType: 'sliding',\n *   }\n * );\n *\n * // Will execute immediately until limit reached, then block\n * rateLimiter.maybeExecute('123');\n * ```\n */\nexport class RateLimiter<TFn extends AnyFunction> {\n  readonly store: Store<Readonly<RateLimiterState>> =\n    new Store<RateLimiterState>(getDefaultRateLimiterState())\n  key: string | undefined\n  options: RateLimiterOptions<TFn>\n  #timeoutIds: Set<NodeJS.Timeout> = new Set()\n\n  constructor(\n    public fn: TFn,\n    initialOptions: RateLimiterOptions<TFn>,\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n    }\n    this.#setState(this.options.initialState ?? {})\n    for (const executionTime of this.#getExecutionTimesInWindow()) {\n      this.#setCleanupTimeout(executionTime)\n    }\n\n    if (this.key) {\n      pacerEventClient.on('d-RateLimiter', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(event.payload.store.state as Partial<RateLimiterState>)\n        this.setOptions(\n          event.payload.options as Partial<RateLimiterOptions<TFn>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the rate limiter options\n   */\n  setOptions = (newOptions: Partial<RateLimiterOptions<TFn>>): void => {\n    this.options = { ...this.options, ...newOptions }\n  }\n\n  #setState = (newState: Partial<RateLimiterState>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const isExceeded = combinedState.executionTimes.length >= this.#getLimit()\n      const status = !this.#getEnabled()\n        ?

This can lead to \"bursty\" behavior where\n * all executions happen immediately, followed by a complete block.\n * This synchronous version is lighter weight and often all you need - upgrade to AsyncRateLimiter when you need promises, retry support, abort capabilities, or advanced error handling.\n *\n * The rate limiter supports two types of windows:\n * - 'fixed': A strict window that resets after the window period. All executions within the window count\n *   towards the limit, and the window resets completely after the period.\n * - 'sliding': A rolling window that allows executions as old ones expire. This provides a more\n *   consistent rate of execution over time.\n *\n * For smoother execution patterns, consider using:\n * - Throttling: Ensures consistent spacing between executions (e.g. max once per 200ms)\n * - Debouncing: Waits for a pause in calls before executing (e.g. after 500ms of no calls)\n *\n * Rate limiting is best used for hard API limits or resource constraints. For UI updates or\n * smoothing out frequent events, throttling or debouncing usually provide better user experience.\n *\n * State Management:\n * - Uses TanStack Store for reactive state management\n * - Use `initialState` to provide initial state values when creating the rate limiter\n * - Use `onExecute` callback to react to function execution and implement custom logic\n * - Use `onReject` callback to react to executions being rejected when rate limit is exceeded\n * - The state includes execution count, execution times, and rejection count\n * - State can be accessed via `rateLimiter.store.state` when using the class directly\n * - When using framework adapters (React/Solid), state is accessed from `rateLimiter.state`\n *\n * @example\n * ```ts\n * const rateLimiter = new RateLimiter(\n *   (id: string) => api.getData(id),\n *   {\n *     limit: 5,\n *     window: 1000,\n *     windowType: 'sliding',\n *   }\n * );\n *\n * // Will execute immediately until limit reached, then block\n * rateLimiter.maybeExecute('123');\n * ```\n */\nexport class RateLimiter<TFn extends AnyFunction> {\n  readonly store: Store<Readonly<RateLimiterState>> =\n    new Store<RateLimiterState>(getDefaultRateLimiterState())\n  key: string | undefined\n  options: RateLimiterOptions<TFn>\n  #timeoutIds: Set<ReturnType<typeof setTimeout>> = new Set()\n\n  constructor(\n    public fn: TFn,\n    initialOptions: RateLimiterOptions<TFn>,\n  ) {\n    this.key = initialOptions.key\n    this.options = {\n      ...defaultOptions,\n      ...initialOptions,\n    }\n    this.#setState(this.options.initialState ?? {})\n    for (const executionTime of this.#getExecutionTimesInWindow()) {\n      this.#setCleanupTimeout(executionTime)\n    }\n\n    if (this.key) {\n      pacerEventClient.on('d-RateLimiter', (event) => {\n        if (event.payload.key !== this.key) return\n        this.#setState(event.payload.store.state as Partial<RateLimiterState>)\n        this.setOptions(\n          event.payload.options as Partial<RateLimiterOptions<TFn>>,\n        )\n      })\n    }\n  }\n\n  /**\n   * Updates the rate limiter options\n   */\n  setOptions = (newOptions: Partial<RateLimiterOptions<TFn>>): void => {\n    this.options = { ...this.options, ...newOptions }\n  }\n\n  #setState = (newState: Partial<RateLimiterState>): void => {\n    this.store.setState((state) => {\n      const combinedState = {\n        ...state,\n        ...newState,\n      }\n      const isExceeded = combinedState.executionTimes.length >= this.#getLimit()\n      const status = !this.#getEnabled()\n        ?
