Import

import { RefHashMap } from "@typed/fx";

Access RefHashMap.filter through the imported RefHashMap export. Its declaration below describes the member.

This public exposure is a re-export. Its import path is supported; declaration documentation is shared with the other public exposures below.

Signatures

export declare const filter: {
    <K, V>(predicate: (value: V, key: K) => boolean): <E, R>(ref: RefHashMap<K, V, E, R>) => Effect.Effect<HashMap.HashMap<K, V>, E, R>;
    <K, V, E, R>(ref: RefHashMap<K, V, E, R>, predicate: (value: V, key: K) => boolean): Effect.Effect<HashMap.HashMap<K, V>, E, R>;
};

Why

Applies filter to the committed HashMap through RefSubject.update and publishes one coherent replacement; this is a mutation, not a read-only Computed projection.

Ownership and lifetime

The Effect starts when run, participates in the source ref’s serialized update boundary, and acquires no resource. It returns the committed HashMap and retains the ref’s E and R channels.

Other public imports

These import paths expose the same declaration. Each page retains its own public name and signature.
