# getValue

Get the value from the Option as a Filtered (fails if None).

## Signatures

```ts
export declare const getValue: <A, E, R>(ref: RefOption<A, E, R>) => RefSubject.Filtered<A, E, R>;
```

## Why

Models the possibly absent result of get value as Filtered state, so absence stays explicit
while later source versions can make a value available.

## Ownership and lifetime

The get value view retains no independent value. Its Effect read fails with NoSuchElement
while absent; the observing Scope owns and finalizes its Fx subscription.
