### `StreamingResponse`

Takes an async generator or a normal generator/iterator and streams the response body.

```Python hl_lines="2  14"
{!../../docs_src/custom_response/tutorial007.py!}
```

#### Using `StreamingResponse` with file-like objects

If you have a file-like object (e.g. the object returned by `open()`), you can create a generator function to iterate over that file-like object.

    this.generator = generator;
    this.collectionSize = collectionSize;
  }

  @Override
  public TestContainerGenerator<T, E> getInnerGenerator() {
    return generator;
  }

  @Override
  public SampleElements<E> samples() {
    return generator.samples();
  }

  @Override
  public T create(Object... elements) {
    return generator.create(elements);
