Import
import { RefString } from "@typed/fx";Access RefString.startsWith through the imported RefString 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 startsWith: {
(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 starts with a substring. The operation remains attached to the RefSubject’s versioned state boundary.
Ownership and lifetime
The starts with 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.
