Import
import { filterMap } from "@typed/fx/RefIterable";Signatures
export declare const filterMap: {
<A>(f: (a: A, index: number) => Option.Option<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) => Option.Option<A>): Effect.Effect<Iterable<A>, E, R>;
};Why
Applies filterMap to the committed Iterable through RefSubject.update and publishes one
coherent replacement; this is a mutation, not a read-only Computed projection.
Ownership and lifetime
The Effect starts when run, participates in the source ref’s serialized update boundary, and acquires no resource. It returns the committed Iterable and retains the ref’s E and R channels.
Other public imports
These import paths expose the same declaration. Each page retains its own public name and signature.
