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

### v1.1+

Version 1.1 added inline data, which will be placed after the metadata.

Therefore, the metadata is wrapped as a binary array for easy skipping.
