Import
import { flatMap } from "@typed/fx/RefIterable";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.
