Import

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

Access RefTrie.get through the imported RefTrie 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 get: {
    (key: string): <V, E, R>(ref: RefTrie<V, E, R>) => RefSubject.Filtered<V, E, R>;
    <V, E, R>(ref: RefTrie<V, E, R>, key: string): RefSubject.Filtered<V, E, R>;
};

Why

Models the possibly absent result of get as Filtered state, so absence stays explicit while later source versions can make a value available.

Ownership and lifetime

The get 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.
