Import

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

Access RefTuple.length through the imported RefTuple 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 length: <T extends ReadonlyArray<unknown>, E, R>(ref: RefTuple<T, E, R>) => RefSubject.Computed<number, E, R>;

Why

Makes length a live projection of the tuple; consumers can sample it now or observe it without copying the source state.

Ownership and lifetime

The length 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.
