compress-lib 0.1.0

DEFLATE, zlib, and gzip for Rust services: streaming and sans-IO with bounded memory, hard limits against decompression bombs, WebSocket permessage-deflate (RFC 7692) support, no unsafe code, and zero third-party dependencies.

Scope

Raw DEFLATE inflate and deflate with window bits 8 to 15 and levels 0 to 9; sync, full, and finish flushes; zlib and gzip framing with checksums always verified; preset dictionaries; per-message compression for WebSocket servers and clients (context takeover on or off); CRC-32 and Adler-32; std::io adapters. Brotli follows after 1.0. It does not negotiate HTTP or WebSocket headers (http-net and ws-net do) and it does not read archives.

Quick start (planned API, from 0.5)

[dependencies]
compress = { package = "compress-lib", version = "0.1" }

let packed = compress::gzip::compress(body);          // Vec<u8>, level 6
let body = compress::gzip::decompress(&packed)?;      // capped at 64 MiB by default

The complete planned API, with the version each item arrives in, is in dev/PLAN.md section 6.
