Import

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

Access RefHashRing.getNode through the imported RefHashRing 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 getNode: {
    (input: string): <A extends PrimaryKey.PrimaryKey, E, R>(ref: RefHashRing<A, E, R>) => RefSubject.Computed<A | undefined, E, R>;
    <A extends PrimaryKey.PrimaryKey, E, R>(ref: RefHashRing<A, E, R>, input: string): RefSubject.Computed<A | undefined, E, R>;
};

Why

Projects the selected node for current reads and later pushes. An empty ring is represented by undefined inside the Computed value; it does not become Filtered or add NoSuchElementError.

Ownership and lifetime

The get node 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.
