Import

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

Access RefOption.isSome through the imported RefOption export. Its declaration below describes the member.

This public exposure is a re-export. Its import path is supported; declaration documentation is shared with the other public exposures below.

Signatures

export declare const isSome: <A, E, R>(ref: RefOption<A, E, R>) => RefSubject.Computed<boolean, E, R>;

Why

Exposes whether the current Option is Some as Computed state, keeping the boolean synchronized with every later source version.

Ownership and lifetime

The is some 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.
