@rei-network/utils

Utils include the following classes:

• Channel: Contains three implements
  • Channel: An asynchronous queue, order by the order in which the elements are pushed
  • HChannel: An asynchronous queue, order by customizable heap
  • PChannel: An asynchronous queue, order by element index(grow from 0) and index must be continuous
• Compress: Provide some functions for compressing and decompressing data
• FunctionalMap and FunctionalSet: Key customizable map and set

INSTALL

npm install @rei-network/utils

USAGE

const channel = new Channel<string>();
channel.push("123");
channel.push("456");
setTimeout(() => {
  channel.push("789");
}, 1000);
setTimeout(() => {
  channel.push("101112");
}, 2000);
setTimeout(() => {
  channel.abort();
}, 3000);

(async () => {
  for await (const data of channel.generator()) {
    console.log("data:", data);
  }
  console.log("channel end");
})();

const bufferMap = new FunctionalMap<Buffer, string>((a: Buffer, b: Buffer) =>
  a.compare(b)
);
bufferMap.set(Buffer.from("aaaaaa", "hex"), "aaaaaa");
console.log(bufferMap.get(Buffer.from("aaaaaa", "hex")) === "aaaaaa"); // true
