Import

import { has } from "@typed/fx/RefHashRing";

Signatures

export declare const has: {
    <A extends PrimaryKey.PrimaryKey>(node: A): <E, R>(ref: RefHashRing<A, E, R>) => RefSubject.Computed<boolean, E, R>;
    <A extends PrimaryKey.PrimaryKey, E, R>(ref: RefHashRing<A, E, R>, node: A): RefSubject.Computed<boolean, E, R>;
};

Why

Makes has a live projection of the hash ring; consumers can sample it now or observe it without copying the source state.

Ownership and lifetime

The has view retains no independent state. An Effect read samples the source once; Fx observation follows later pushes and its observing Scope owns subscription cleanup.

Other public imports

These import paths expose the same declaration. Each page retains its own public name and signature.
