Import
import { modify } from "@typed/fx/RefRecord";Signatures
export declare const modify: {
<K extends string, V>(key: K, f: (v: 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>, key: K, f: (v: V) => V): Effect.Effect<Record.ReadonlyRecord<K, V>, E, R>;
};Why
Keeps modify atomic with respect to competing RefSubject writes instead of splitting the read and replacement into separate effects.
Ownership and lifetime
Running modify 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.
