Import
import { isBefore } from "@typed/fx/RefDateTime";Signatures
export declare const isBefore: {
(that: DateTime.DateTime): <E, R>(ref: RefDateTime<E, R>) => RefSubject.Computed<boolean, E, R>;
<E, R>(ref: RefDateTime<E, R>, that: DateTime.DateTime): RefSubject.Computed<boolean, E, R>;
};Why
Check if the current state of a RefDateTime is before another DateTime. The operation remains attached to the RefSubject’s versioned state boundary.
Ownership and lifetime
The is before 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.
