Import

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

Access RefChunk.prepend through the imported RefChunk 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 prepend: {
    <A>(value: A): <E, R>(ref: RefChunk<A, E, R>) => Effect.Effect<Chunk.Chunk<A>, E, R>;
    <A, E, R>(ref: RefChunk<A, E, R>, value: A): Effect.Effect<Chunk.Chunk<A>, E, R>;
};

Why

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

Ownership and lifetime

Running prepend performs one serialized chunk 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.
