@rimbu/multimap

A Rimbu MultiMap is a Map in which each key has one or more values. For each key, it's associated values are unique, that is, the values for each key are kept in a Set.

This package exports the following types:

Name	Description
HashMultiMapHashValue<K, V>	a multimap between hashed values of type K and hashed values of type V
HashMultiMapSortedValue<K, V>	a multimap between hashed values of type K and sorted values of type V
MultiMap<K, V>	a generic multimap between values of type K and values of type V
SortedMultiMapHashValue<K, V>	a multimap between sorted values of type K and hashed values of type V
SortedMultiMapSortedValue<K, V>	a multimap between sorted values of type K and sorted values of type V
VariantMultiMap<K, V>	a type-variant multimap between values of type K and values of type V

For complete documentation please visit the MultiMap page in the Rimbu Docs, or directly see the Rimbu MultiMap 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/multimap

or

npm i @rimbu/multimap

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 { HashMultiMapHashValue } from '@rimbu/multimap';

console.log(HashMultiMapHashValue.of([1, 2], [1, 3], [2, 3]).toString());
