# remove

Remove a key from the RefHashMap.

## Signatures

```ts
export declare const remove: {
    <K>(key: K): <V, E, R>(ref: RefHashMap<K, V, E, R>) => Effect.Effect<HashMap.HashMap<K, V>, E, R>;
    <K, V, E, R>(ref: RefHashMap<K, V, E, R>, key: K): Effect.Effect<HashMap.HashMap<K, V>, E, R>;
};
```

## Why

Applies remove to the committed hash map value and publishes only the result, preserving its
element order and equality rules.

## Ownership and lifetime

Running remove performs one serialized hash map transition and resolves with its committed
value. It acquires no resource; failures and services remain those of the source ref.
