OxiArc Zstandard

Pure Rust implementation of the Zstandard (zstd) compression format (RFC 8878).

Zstandard is a modern, fast compression algorithm providing excellent compression ratios. This implementation provides decompression and basic compression support.

Features

• Complete Zstandard frame parsing
• FSE (Finite State Entropy) decoding
• Huffman decoding for literals
• Raw block compression (valid Zstd output)
• XXH64 checksum verification

Example

use oxiarc_zstd::{compress, decompress};

let data = b"Hello, Zstandard!";
let compressed = compress(data).unwrap();
let decompressed = decompress(&compressed).unwrap();
assert_eq!(decompressed, data);
