Write stream chunks directly to the output stream

[mokhaled2992]

I asked this question in the axum discussions section and I was referred here. I want to stream byte chunks to the output stream directly without having to yield those chunks in separate allocations. Perhaps there is a way to get some handle to the output stream and write the chunks directly to it? Is such a thing possible?

There is no current way to do that, and likely won't be added. Granted, hyper doesn't require you provide the Bytes type itself, but really any owned type that implements Buf. So if you have a more optimal way you wish to store the data, you could do that.

If you're writing data to a Vec<u8>, you could instead push it into a BytesMut and then slice off parts. That tries to reuse the allocation as much as possible.
