Wanted to extend hpack encoders or allow different Encoder and Decoders to be used.

I have a library coming out which I made as a drop in replacement for python hpack called cyhpack and I wanted to try developing a better solution for injecting my own Decoder and Encoder which runs ls-hpack under the hood. As of currently, here is my workaround but I was wondering if a better implementation could be implemented such as a factory attribute or an Abstract class could be made to accommodate my version and the pure python one as well?

from __future__ import annotations

from h2.config import H2Configuration
from h2.connection import H2Connection as _H2Connection

from .hpack import Decoder, Encoder


class H2Connection(_H2Connection):
    """
    Contains an overridable version of H2Connection that drops
    python hpack in exchange for cyhpack for faster performance
    and speed.
    """

    def __init__(self, config: H2Configuration | None = None):
        super().__init__(config)
        self.encoder = Encoder()
        self.decoder = Decoder()

Commencez par lire h2.connection.H2Connection et H2Configuration, puis comparez la manière dont l’Encoder et le Decoder actuels sont initialisés avec la solution de contournement par sous-classe présentée dans l’issue. Le travail est terminé lorsque les appelants peuvent utiliser d’autres implémentations d’Encoder et de Decoder sans maintenir une sous-classe personnalisée de H2Connection, avec une couverture du chemin de configuration.
