# appendAll

Append an iterable of values to the current state of a RefIterable.

## Signatures

```ts
export declare const appendAll: {
    <A>(value: Iterable<A>): <E, R>(ref: RefIterable<A, E, R>) => Effect.Effect<Iterable<A>, E, R>;
    <A, E, R>(ref: RefIterable<A, E, R>, value: Iterable<A>): Effect.Effect<Iterable<A>, E, R>;
};
```

## Why

Expresses append all as one ordered iterable transition; readers never observe the intermediate
collection used to build the result.

## Ownership and lifetime

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