Import

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

Access RefIterable.flatMap 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 flatMap: {
    <A>(f: (a: A, index: number) => Iterable<A>): <E, R>(ref: RefIterable<A, E, R>) => Effect.Effect<Iterable<A>, E, R>;
    <A, E, R>(ref: RefIterable<A, E, R>, f: (a: A, index: number) => Iterable<A>): Effect.Effect<Iterable<A>, E, R>;
};

Why

FlatMap (endomorphic). The operation remains attached to the RefSubject’s versioned state boundary.

Ownership and lifetime

Running flat map 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.
