zip_parser

Zip file format parser implemented by rust. support stream parsing, no_std environment.

The Parser will search central directory at the end of zip file if Seek is available. Also, It supports sequence read parsing when Seek is not available. The type which implements std::io::Read implements Read in std env, and so is the Seek.

stream parsing

fn parse<S: zip::Read + zip::Seek>(mut parser: Parser<S>) {
    for (i, mut file) in parser.enumerate() {
        println!("{}: {}({} Bytes)", i, unsafe { file.file_name() }, file.file_size());
        let mut buf = Vec::new();
        buf.resize(file.file_size() as usize, 0);
        if let Ok(n) = file.read(&mut buf) {
            println!("Data: {:02X?}", &buf[..n]);
        } else {
            println!("read failed");
        }
        println!();
    }
}

fn stdin_parsing() {
    println!("*** get stream from stdin ***");
    parse(Parser::new(stdin().lock()))
}

You just need to pass a stream which implements Read into the Parser::new(), then you can iterate over it. For more detail, see example stream_parsing

example

stream_parsing

1. from stdin

   cat test.zip | cargo run --features="std" --example stream_parsing
   

   or even you can cat multiple zip files:

   cat test.zip test.zip | cargo run --features="std" --example stream_parsing
   

2. from file

   cargo run --features="std" --example stream_parsing -- test.zip
