stream-unpacker

一个用于解压缩存档的小型库（例如，同时下载和解压缩）。目前支持单文件、多部分和伪多部分（单个存档分割成多个文件）ZIP，支持DEFLATE压缩和解压缩。此库要求您首先获取要解压缩的ZIP的中心目录，并提供方便实现此操作的实用工具。

示例

请查看此仓库中的完整示例。

let archive = fs::read("archive.zip").unwrap();

let central_directory = read_cd::from_provider(
    vec![archive.len()],
    false, // Determines whether to interpret it as a fake multipart (cut) archive
    |pos, length| Ok(archive[(pos.offset)..(pos.offset + length)].to_owned())
).unwrap();

let mut unpacker = ZipUnpacker::new(central_directory.sort(), vec![archive.len()]);
unpacker.set_callback(|data| {
    println!("Got data: {data:?}");
    // Do something useful with data. See full examples

    Ok(())
});

// You can provide an arbitrary amount of bytes at a time
// Make sure to advance the buffer exactly the amount of bytes returned
// All split archives (multipart and fake multipart) should be treated
// as a continuous stream of bytes from the first one to the last one
let (advanced, reached_end) = unpacker.update(archive).unwrap();

println!("Done!");
