@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 Map or Set page Rimbu Docs, or directly see the Rimbu Hashed API Docs.

Or Try Out Rimbu in CodeSandBox.

Installation

For convenience, all main types are also exported through @rimbu/core.

To install separately:

Yarn/NPM

yarn add @rimbu/hashed

or

npm i @rimbu/hashed

Deno

For Deno, the following approach is recommended:

In the root folder of your project, create or edit a file called import_map.json with the following contents (where you should replace x.y.z with the desired version of Rimbu):

{
  "imports": {
    "@rimbu/": "https://deno.land/x/rimbu@x.y.z/"
  }
}

Note: The trailing slashes are important!

In this way you can use relative imports from Rimbu in your code, like so:

import { List } from '@rimbu/core/mod.ts';
import { HashMap } from '@rimbu/hashed/mod.ts';

Note that for sub-packages, due to conversion limitations it is needed to import the index.ts instead of mod.ts, like so:

import { HashMap } from '@rimbu/hashed/map/index.ts';

To run your script (let's assume the entry point is in src/main.ts):

deno run --import-map import_map.json src/main.ts

Because Rimbu uses advanced types, this may slow down the type checking part when running your code. If you're able to rely on your code editor to provide type errors, you can skip the Deno type check using the --no-check flag:

deno run --import-map import_map.json --no-check src/main.ts

Usage

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

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