Import
import { union } from "@typed/fx/RefRecord";Signatures
export declare const union: {
<K extends string, V>(that: Record.ReadonlyRecord<K, V>, combine?: (selfValue: V, thatValue: V) => V): <E, R>(ref: RefRecord<K, V, E, R>) => Effect.Effect<Record.ReadonlyRecord<K, V>, E, R>;
<K extends string, V, E, R>(ref: RefRecord<K, V, E, R>, that: Record.ReadonlyRecord<K, V>, combine?: (selfValue: V, thatValue: V) => V): Effect.Effect<Record.ReadonlyRecord<K, V>, E, R>;
};Why
Combines bulk record changes in one committed value, giving subscribers one coherent update rather than a partially applied sequence.
Ownership and lifetime
Running union performs one serialized record 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.
