@rimbu/multiset

A Rimbu MultiSet is a Set-like structure where each unique element can be added multiple times. Each element in the MultiSet occurs one or more times. The MultiSet keeps track of the amount of times an element was added.

This package exports the following main types:

Name	Description
HashMultiSet<T>	a MultiSet with hashed elements of type T
MultiSet<T>	a generic MultiSet with elements of type T
SortedMultiSet<T>	a MultiSet with sorted elements of type T
VariantMultiSet<T>	a type-variant MultiSet with elements of type T

For complete documentation please visit the MultiSet page in the Rimbu Docs, or directly see the Rimbu MultiSet API Docs.

Or Try Out Rimbu in CodeSandBox.

Installation

Compabitity

• Node >= 16
• Deno
• Bun >= 0.6.0
• Web

Yarn / NPM / Bun

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

To install this package only:

For yarn:

yarn add @rimbu/multiset

For npm:

npm i @rimbu/multiset

For bun:

bun add @rimbu/multiset

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

Usage

import { SortedMultiSet } from '@rimbu/multiset';

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