Import

import { includes } from "@typed/fx/RefString";

Signatures

export declare const includes: {
    (searchString: string, position?: number): <E, R>(ref: RefString<E, R>) => RefSubject.Computed<boolean, E, R>;
    <E, R>(ref: RefString<E, R>, searchString: string, position?: number): RefSubject.Computed<boolean, E, R>;
};

Why

Check if the current state of a RefString includes a substring. The operation remains attached to the RefSubject’s versioned state boundary.

Ownership and lifetime

The includes 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.
