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()

首先阅读 h2.connection.H2Connection 和 H2Configuration，然后将当前 Encoder 和 Decoder 的初始化方式与 issue 中所示的子类变通方案进行比较。当调用方无需维护自定义 H2Connection 子类即可使用替代的 Encoder 和 Decoder 实现，并且配置路径有覆盖时，工作就完成了。
