@rimbu/hashed

This package contains the implementation for the HashMap and HashSet types, which form the basis of all Rimbu Hashed collections. The collections use a Hasher instance that is configurable to determine the equality of values/objects.

This package exports the following main types:

Name	Description
HashMap<K, V>	a map with entries of key type K and value type V, where keys are hashed with a Hasher
HashSet<T>	a set of value type T where items are hashed with a Hasher

For complete documentation please visit the Rimbu Docs.

Or Try Me Out in CodeSandBox.

Installation

All types are exported through @rimbu/core. It is recommended to use that package.

To install separately:

Yarn/NPM

yarn add @rimbu/hashed

or

npm i @rimbu/hashed

Deno

Create a file called rimbu.ts and add the following:

export * from 'https://deno.land/x/rimbu/hashed/mod.ts';

Or using a pinned version (x.y.z):

export * from 'https://deno.land/x/rimbu/hashed@x.y.z/mod.ts';

Then import what you need from rimbu.ts:

import { HashSet } from './rimbu.ts';

Because Rimbu uses complex types, it's recommended to use the --no-check flag (your editor should already have checked your code) and to specify a tsconfig.json file with the settings described below.

Running your script then becomes:

deno run --no-check --config tsconfig.json <your-script>.ts

Recommended tsconfig.json settings

Rimbu uses advanced and recursive typing, potentially making the TypeScript compiler quite slow in some cases, or causing infinite recursion. It is recommended to set the following values in the tsconfig.json file of your project:

{
  "compilerOptions": {
    "skipLibCheck": true,
    "noStrictGenericChecks": true
  }
}

Usage

import { HashSet } from '@rimbu/hashed';

console.log(HashSet.of(1, 3, 2, 4, 3, 1).toString());
