Import

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

Access RefIterable.prependAll through the imported RefIterable 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 prependAll: {
    <A>(value: Iterable<A>): <E, R>(ref: RefIterable<A, E, R>) => Effect.Effect<Iterable<A>, E, R>;
    <A, E, R>(ref: RefIterable<A, E, R>, value: Iterable<A>): Effect.Effect<Iterable<A>, E, R>;
};

Why

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

Ownership and lifetime

Running prepend all performs one serialized iterable 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.
