# RefChunk.prepend

Prepend a value to the current state of a RefChunk.

## Signatures

```ts
export declare const prepend: {
    <A>(value: A): <E, R>(ref: RefChunk<A, E, R>) => Effect.Effect<Chunk.Chunk<A>, E, R>;
    <A, E, R>(ref: RefChunk<A, E, R>, value: A): Effect.Effect<Chunk.Chunk<A>, E, R>;
};
```

## Why

Expresses prepend as one ordered chunk transition; readers never observe the intermediate
collection used to build the result.

## Ownership and lifetime

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