Crate stuffit 

StuffIt (.sit) archive parser, decompressor, and creator.

This crate provides functionality to read and write StuffIt archives, a compression format popular on classic Macintosh systems.

Supported Formats

• StuffIt 5.0 - The main format with signature at offset 80
• SIT! 1.x - The original StuffIt format

Compression Methods

• Method 0 - No compression (store)
• Method 13 - LZ77 with Huffman coding (StuffIt native)
• Method 14 - Deflate (limited support)
• Method 15 - Arsenic/BWT (read-only)

Example

use stuffit::{SitArchive, SitEntry};

// Parse an existing archive
let data = std::fs::read("archive.sit").unwrap();
let archive = SitArchive::parse(&data).unwrap();

for entry in &archive.entries {
    println!("{}: {} bytes", entry.name, entry.data_fork.len());
}

// Create a new archive
let mut archive = SitArchive::new();
let mut entry = SitEntry::default();
entry.name = "hello.txt".to_string();
entry.data_fork = b"Hello, World!".to_vec();
archive.add_entry(entry);

let bytes = archive.serialize_compressed().unwrap();
std::fs::write("new_archive.sit", bytes).unwrap();
