# RefHashRing.getShards

Get shard distribution across nodes.

## Signatures

```ts
export declare const getShards: {
    (count: number): <A extends PrimaryKey.PrimaryKey, E, R>(ref: RefHashRing<A, E, R>) => RefSubject.Computed<Array<A> | undefined, E, R>;
    <A extends PrimaryKey.PrimaryKey, E, R>(ref: RefHashRing<A, E, R>, count: number): RefSubject.Computed<Array<A> | undefined, E, R>;
};
```

## Why

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