Import
import { head } from "@typed/fx/RefChunk";Signatures
export declare const head: <A, E, R>(ref: RefChunk<A, E, R>) => RefSubject.Filtered<A, E, R>;Why
Models the possibly absent result of head as Filtered state, so absence stays explicit while later source versions can make a value available.
Ownership and lifetime
The head 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.
