Import
import { length } from "@typed/fx/RefTuple";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.
