Import

import { keysWithPrefix } from "@typed/fx/RefTrie";

Signatures

export declare const keysWithPrefix: {
    (prefix: string): <V, E, R>(ref: RefTrie<V, E, R>) => RefSubject.Computed<Array<string>, E, R>;
    <V, E, R>(ref: RefTrie<V, E, R>, prefix: string): RefSubject.Computed<Array<string>, E, R>;
};

Why

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

Ownership and lifetime

The keys with prefix 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.
