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