Import

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

Access RefRecord.keys through the imported RefRecord 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 keys: <K extends string, V, E, R>(ref: RefRecord<K, V, E, R>) => RefSubject.Computed<Array<K>, E, R>;

Why

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

Ownership and lifetime

The keys 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.
