Import
import { findFirst } from "@typed/fx/RefRecord";Signatures
export declare const findFirst: {
<K extends string, V>(predicate: (value: V, key: K) => boolean): <E, R>(ref: RefRecord<K, V, E, R>) => RefSubject.Filtered<[
K,
V
], E, R>;
<K extends string, V, E, R>(ref: RefRecord<K, V, E, R>, predicate: (value: V, key: K) => boolean): RefSubject.Filtered<[
K,
V
], E, R>;
};Why
Models the possibly absent result of find first as Filtered state, so absence stays explicit while later source versions can make a value available.
Ownership and lifetime
The find first view retains no independent value. Its Effect read fails with NoSuchElement while absent; the observing Scope owns and finalizes its Fx subscription.
Other public imports
These import paths expose the same declaration. Each page retains its own public name and signature.
