Import
import { RefHashMap } from "@typed/fx";Access RefHashMap.union through the imported RefHashMap 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 union: {
<K, V>(that: HashMap.HashMap<K, V>): <E, R>(ref: RefHashMap<K, V, E, R>) => Effect.Effect<HashMap.HashMap<K, V>, E, R>;
<K, V, E, R>(ref: RefHashMap<K, V, E, R>, that: HashMap.HashMap<K, V>): Effect.Effect<HashMap.HashMap<K, V>, E, R>;
};Why
Combines bulk hash map 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 map 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.
