Import

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

Access RefArray.append through the imported RefArray 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 append: {
    <A>(value: A): <E, R>(ref: RefArray<A, E, R>) => Effect.Effect<ReadonlyArray<A>, E, R>;
    <A, E, R>(ref: RefArray<A, E, R>, value: A): Effect.Effect<ReadonlyArray<A>, E, R>;
};

Why

Expresses append as one ordered array transition; readers never observe the intermediate collection used to build the result.

Ownership and lifetime

Running append performs one serialized array transition and resolves with its committed value. It acquires no resource; failures and services remain those of the source ref.

Other public imports

These import paths expose the same declaration. Each page retains its own public name and signature.
