Import
import { addDuration } from "@typed/fx/RefDateTime";Signatures
export declare const addDuration: {
(duration: Duration.Input): <E, R>(ref: RefDateTime<E, R>) => RefSubject.Computed<DateTime.DateTime, E, R>;
<E, R>(ref: RefDateTime<E, R>, duration: Duration.Input): RefSubject.Computed<DateTime.DateTime, E, R>;
};Why
Add a Duration to the current state of a RefDateTime. The operation remains attached to the RefSubject’s versioned state boundary.
Ownership and lifetime
The add duration 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.
