Import

import { set } from "@typed/fx/RefStruct";

Signatures

export declare const set: {
    <S extends object, K extends keyof S>(key: K, value: S[K]): <E, R>(ref: RefStruct<S, E, R>) => Effect.Effect<S, E, R>;
    <S extends object, K extends keyof S, E, R>(ref: RefStruct<S, E, R>, key: K, value: S[K]): Effect.Effect<S, E, R>;
};

Why

Keeps set atomic with respect to competing RefSubject writes instead of splitting the read and replacement into separate effects.

Ownership and lifetime

Running set performs one serialized struct 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.
