Import

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

Access RefHashMap.some 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 some: {
    <K, V>(predicate: (value: V, key: K) => boolean): <E, R>(ref: RefHashMap<K, V, E, R>) => RefSubject.Computed<boolean, E, R>;
    <K, V, E, R>(ref: RefHashMap<K, V, E, R>, predicate: (value: V, key: K) => boolean): RefSubject.Computed<boolean, E, R>;
};

Why

Makes some a live projection of the hash map; consumers can sample it now or observe it without copying the source state.

Ownership and lifetime

The some 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.
