Import
import { Versioned } from "@typed/fx";Access Versioned.filterMap through the imported Versioned 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 filterMap: {
<A, E, R, C, B, D>(options: {
onFx: (a: A) => Option.Option<C>;
onEffect: (b: B) => Option.Option<D>;
}): <R0, E0, R2, E2>(versioned: Versioned<R0, E0, A, E, R, B, E2, R2>) => Versioned<never, never, C, E, R, Option.Option<D>, E0 | E2, R0 | R2>;
<R0, E0, A, E, R, B, E2, R2, C, D>(versioned: Versioned<R0, E0, A, E, R, B, E2, R2>, options: {
onFx: (a: A) => Option.Option<C>;
onEffect: (b: B) => Option.Option<D>;
}): Versioned<never, never, C, E, R, Option.Option<D>, E0 | E2, R0 | R2>;
};Why
Drops absent pushed values while preserving an Option for the current read, making the two absence semantics explicit.
Ownership and lifetime
filterMap does not take ownership of its inputs. Its observation and current-read channels retain upstream lifetime, typed failures, services, and interruption behavior.
Other public imports
These import paths expose the same declaration. Each page retains its own public name and signature.
