Import
import { isSome } from "@typed/fx/RefOption";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.
