Hyper-h2: A pure-Python HTTP/2 protocol stack

Hyper-h2 is a HTTP/2 protocol stack, written entirely in Python. The goal of Hyper-h2 is to be a common HTTP/2 stack for the Python ecosystem, usable in all programs regardless of concurrency model or environment.

To achieve this, Hyper-h2 is entirely self-contained: it does no I/O of any kind, leaving that up to a wrapper library to control. This ensures that it can seamlessly work in all kinds of environments, from single-threaded code to Twisted.

Its goal is to be 100% compatible with RFC 7540, implementing a complete HTTP/2 protocol stack build on a set of finite state machines. Its secondary goals are to be fast, clear, and efficient.
