Lossless compression C library built for ultra-fast decode. Faster than LZ4 (40-75%+ on ARM64), at a better ratio. Official Rust, Python, Node.js, Go and WASM bindings. Write-once/read-many, with optional seekable archives for O(1) random access.
Pure Rust Zstandard (zstd) compression library and CLI: drop-in libzstd replacement with a C ABI, levels 1-22, streaming, dictionaries, long-distance matching, SIMD, no_std and WebAssembly. No C, no FFI, no cmake.
Pure-Rust, no_std collection of 30+ compression/decompression codecs (deflate, gzip, zlib, zstd, brotli, lzma/xz, lz4, bzip2, RAR, StuffIt, LHA, ARC, and more) behind one uniform streaming trait — each gated by its own Cargo feature. 100% safe (forbid(unsafe_code)), zero runtime deps.
GPL-free, safe, no_std pure-Rust LZO1X decompressor — decode lzo1x_1 / lzo1x_999 streams (lzop, kernel/initramfs, btrfs, liblzo2) with zero C, zero dependencies, and #![forbid(unsafe_code)]; validated against liblzo2 and fuzz-hardened against malicious input.
