A basic implementation of HTTP2 in rust. This implementation receives http2 requests and provides them to a handler function in http 1.1 semantics. Response returned by the handler in http 1.1 semantics is then converted to http2 and sent.
This implementation has been tested with a basic GET and POST request via h2load.

This implementation is NOT http2 compliant, however it can be extended to do so. I however doubt I'll continue this project as this project was mostly for learning about http2 by reading the rfc and practicing some rust.
$ cargo run # to run the server
$ h2load http://localhost:8080 -v# to make http2 req
$ sudo tshark -i any -f "tcp port 8080" -Y "http2" -V # to monitor http2 requests
$ ~/Downloads/h2spec -p 8080 http2 # for checking compliance, you might have it somewhere else.
