Import

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

Access RefChunk.filterValues through the imported RefChunk 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 filterValues: {
    <A>(predicate: (a: A) => boolean): <E, R>(ref: RefChunk<A, E, R>) => RefSubject.Computed<Chunk.Chunk<A>, E, R>;
    <A, E, R>(ref: RefChunk<A, E, R>, predicate: (a: A) => boolean): RefSubject.Computed<Chunk.Chunk<A>, E, R>;
};

Why

Projects chunk state with filter values for both current reads and future pushes, avoiding a second mutable cache of the derived value.

Ownership and lifetime

The filter values view retains no independent state. An Effect read samples the source once; Fx observation follows later pushes and its observing Scope owns subscription cleanup.

Other public imports

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