Interfaces

A mutable HashMap builder used to efficiently create new immutable instances. See the Map documentation and the HashMap.Builder API documentation

A context instance for a HashMap that acts as a factory for every instance of this type of collection.

A non-empty type-invariant immutable Map of key type K, and value type V. In the Map, each key has exactly one value, and the Map cannot contain duplicate keys.

  • The HashMap uses the context's hasher instance to hash keys for performance.
  • The HashMap uses the context's eq function to determine equivalence between keys.

Utility interface that provides higher-kinded types for this collection.

interface HashMap
implements RMapBase<K, V, HashMap.Types>
import { type HashMap } from "https://deno.land/x/rimbu@0.14.0/hashed/map/index.ts";

A type-invariant immutable Map of key type K, and value type V. In the Map, each key has exactly one value, and the Map cannot contain duplicate keys.

  • The HashMap uses the context's hasher instance to hash keys for performance.
  • The HashMap uses the context's eq function to determine equivalence between keys.
