Module hpack 

HPACK (RFC 7541): header compression for HTTP/2.

Asymmetric on purpose. Decoding must be complete, because the server decides how to encode and Go’s HTTP/2 server uses the dynamic table and Huffman freely. Encoding can be as simple as we like, because a literal, unindexed, uncompressed header is always legal — so this crate emits those and keeps no encoder-side table at all.

That asymmetry removes the hardest failure mode. An encoder dynamic table has to stay in step with the peer’s decoder copy, and a divergence corrupts every subsequent header rather than failing outright. Not having one cannot diverge.
