<pre />

Finalizer used to synthesize the aggregate streaming response payload.

A failed finalizer yields a `null` aggregate with no `data` fallback and marks the END event ERROR. Any `FnOnce() -> Json` converts into the infallible form.

## Variants

### `Sync(Box<dyn FnOnce() -> Value + Send>)`

<pre />

Returns the aggregate directly.

### `Fallible(Box<dyn FnOnce() -> Result<Value, FlowError> + Send>)`

<pre />

Returns the aggregate or a failure.

### `Async(Box<dyn FnOnce() -> Pin<Box<dyn Future<Output = Result<Value, FlowError>> + Send>> + Send>)`

<pre />

Awaited before the END publication, so a flush inside it does not wait on this stream or other unfinished terminal publications.

## Implementations

### `impl LlmFinalizer`

<pre />

#### `new_async`

<pre />

Wrap a future-returning closure as an asynchronous finalizer.

## Trait Implementations

### `impl<F> From<F> for LlmFinalizerwhere F: FnOnce() -> Value + Send + 'static,`

<pre />

#### `from`
