Module hpack 

Available on crate features h2 or h3 only.

Primitives shared between HPACK (RFC 7541) and QPACK (RFC 9204).

Both header-compression schemes use the same Huffman code (RFC 7541 Appendix B, reused verbatim by RFC 9204 Section 4.2) and the same prefix-integer representation (RFC 7541 Section 5.1, reused by RFC 9204 Section 4.3). These live here, one level up from the protocol modules that consume them, so neither codec needs to depend on the other.

Consumers: h2::hpack (HPACK) and h3::qpack (QPACK).

This module is also the public vibeio_http::hpack path: the HPACK codec surface (Decoder, Encoder, Header) is re-exported from h2::hpack.
