v0.19.1

Yanked due to bug for flate2 version below 1.1. Use 0.19.2 or above instead

Changed

• Gzip backend selection via feature flags:
  • Default feature gz switched to use flate2 with the gz-zlib-rs backend for improved performance.
  • New selectors and aliases:
    • gz-zlib-rs — enables flate2/zlib-rs (Rust, fast)
    • gz-miniz — enables flate2/miniz_oxide (pure Rust, most portable)
  • Disabled flate2 default-features to allow explicit backend choice.

Added

• Criterion benchmark benches/gzip_decompress.rs to measure gzip decompression throughput across backends.

Usage

• Default (zlib-rs):
  • cargo build
  • cargo bench --bench gzip_decompress --features gz
• zlib-rs:
  • cargo build --no-default-features --features gz-zlib-rs
  • cargo bench --bench gzip_decompress --no-default-features --features gz-zlib-rs
• miniz_oxide (explicit):
  • cargo build --no-default-features --features gz-miniz
  • cargo bench --bench gzip_decompress --no-default-features --features gz-miniz
