Import

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

Access RefResult.match through the imported RefResult 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 match: {
    <A, ResultE, B>(options: {
        readonly onSuccess: (a: A) => B;
        readonly onFailure: (e: ResultE) => B;
    }): <Err, R>(ref: RefResult<A, ResultE, Err, R>) => RefSubject.Computed<B, Err, R>;
    <A, ResultE, Err, R, B>(ref: RefResult<A, ResultE, Err, R>, options: {
        readonly onSuccess: (a: A) => B;
        readonly onFailure: (e: ResultE) => B;
    }): RefSubject.Computed<B, Err, R>;
};

Why

Folds both Result variants into one Computed value, applying the same handlers to current reads and subsequent pushes.

Ownership and lifetime

The match 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.
