rh2 0.0.2

Rust-backed sans-IO HTTP/2 codec for Python, wrapping the h2 crate

rh2

A Rust-backed, sans-IO HTTP/2 codec for Python, wrapping the h2 crate (the HTTP/2 implementation behind hyper/reqwest) via PyO3.

The h2 crate drives a connection over an async transport; rh2 runs it sans-IO by backing that transport with in-memory buffers and pumping the state machine by hand. The Python API mirrors hyper-h2:

import rh2

conn = rh2.H2Connection()
events = conn.receive_data(data_from_socket)
for event in events:
    if isinstance(event, rh2.RequestReceived):
        conn.send_headers(event.stream_id, 200, [(b"content-type", b"text/plain")])
        conn.send_data(event.stream_id, b"hello", end_stream=True)
socket.sendall(conn.data_to_send())

Status

Experimental. Server-side only.
