ResponseNotRead and aiter_bytes

[a14n]

The following code open a stream and iter on all chunks.

async with async_client.stream("GET", url) as response:
    status_code = r.status_code
    async for chunk in response.aiter_bytes(chunk_size=max_response_size_b):
        pass
    response.content # should be OK but raise a ResponseNotRead

Although all chunks have been consumed response.content remains unusable (by raising a ResponseNotRead).

It would be great to set response._content once the iteration is over. WDYT?

It's the point of streaming, to not load the entire data into the memory, and if it will not raise an error, what should it return?

ok, I didn't understand the point of streaming.
The initial issue I faced was to ensure the content size was not too big and prevent out of memory. So I stream the response. If the content is too big I raise an error but if the content is small enough I'd like to return a response object where response.content and other are usable (without ResponseNotRead). Today I cheat by setting response._content but it's not clean.
Is there a way to control the content size?

EDIT: BTW with the stream you can call await response.aread() and have response.content usable without ResponseNotRead. So even if it is streaming the entire data ends up in memory.
