Experimental Python hpack implementation using nghttp2.

The API is nearly compatible with hpack. (httpx runs without issues).

It requires Cython because nghttp2pyx requires some updates:

• to raise hpack.exceptions.* instead of a generic Exception
• to handle the sentive flag

About speed:

• the encoder is about 20 times faster
• the decoder is about 10 times faster

How to install

python -m pip install git+https://github.com/dalf/hpack_nghttp2.git

Warning: it will replace the existing the hpack module

Not implemented

• hpack.exceptions.InvalidTableIndex : never raised
• hpack.exceptions.InvalidTableSizeError : never raised
