Protocol::HTTP2 is HTTP/2 protocol (draft 17) implementation with stateful decoders/encoders of HTTP/2 frames. You may use this module to implement your own HTTP/2 client/server/intermediate on top of your favorite event loop over plain or tls socket (see examples).
Current status - alpha. Structures, module names and methods may change vastly. I've started this project to understand internals of HTTP/2 and may be it will never become production or even finished.

Client protocol decoder/encoder with constructor of requests
Server protocol decoder/encoder with constructor of responses/pushes
Main low level module for protocol logic and state processing. Connection object is a mixin of Protocol::HTTP2::Frame (frame encoding/decoding), Protocol::HTTP2::Stream (stream operations) and Protocol::HTTP2::Upgrade (HTTP/1.1 Upgrade support)
Module implements HPACK (draft 11) - Header Compression for HTTP/2. http://tools.ietf.org/html/draft-ietf-httpbis-header-compression-11
Module contain all defined in HTTP/2 protocol constants and default values
Module for debugging. (Ab)used Log::Dispatch internally, may be removed soon.
