Warp: Question: pipe a request body into a file?
I am coming from the Node.js world but I'm looking for something with low latency, type-safety etc.
For my use-case I want to pipe a request body into a file (upload). Is this possible in Warp, without having the full contents in memory?

It is possible. You can get the request body as a stream via warp::body::stream(). And you can get an asynchronous-looking File with tokio-fs. Then you could combine Stream::for_each and tokio::io::write_all to write each chunk to the file. I'm on mobile, but I could later write up what that code looks like.
It does sound like very useful functionality to have directly in warp...
