Import
import { union } from "@typed/fx/RefHashSet";Signatures
export declare const union: {
<V>(that: HashSet.HashSet<V>): <E, R>(ref: RefHashSet<V, E, R>) => Effect.Effect<HashSet.HashSet<V>, E, R>;
<V, E, R>(ref: RefHashSet<V, E, R>, that: HashSet.HashSet<V>): Effect.Effect<HashSet.HashSet<V>, E, R>;
};Why
Combines bulk hash set changes in one committed value, giving subscribers one coherent update rather than a partially applied sequence.
Ownership and lifetime
Running union performs one serialized hash set 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.
