Get the value from the Option as a Filtered (fails if None).

Import

import { getValue } from "@typed/fx/RefOption";

Signatures

export declare const getValue: <A, E, R>(ref: RefOption<A, E, R>) => RefSubject.Filtered<A, E, R>;

Why

Models the possibly absent result of get value as Filtered state, so absence stays explicit while later source versions can make a value available.

Ownership and lifetime

The get value 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.
