Crate oxiarc_deflate 

OxiArc Deflate

Pure Rust implementation of the DEFLATE compression algorithm (RFC 1951).

This crate provides compression and decompression of DEFLATE data, which is the basis for ZIP, GZIP, and PNG formats.

Features

• Decompression: Full support for all DEFLATE block types
  • Stored (uncompressed) blocks
  • Fixed Huffman codes
  • Dynamic Huffman codes
• Compression: LZ77 + Huffman encoding
  • Multiple compression levels (0-9)
  • Fixed Huffman codes

Example

use oxiarc_deflate::{deflate, inflate};

// Compress data
let original = b"Hello, World! Hello, World!";
let compressed = deflate(original, 6).unwrap();

// Decompress data
let decompressed = inflate(&compressed).unwrap();
assert_eq!(&decompressed, original);

Compression Levels

• Level 0: No compression (stored blocks)
• Level 1-3: Fast compression
• Level 4-6: Balanced (default is 6)
• Level 7-9: Best compression (slower)
