tar

A Rust implementation of a TAR file reader and writer. This library does not currently handle compression, but it is abstract over all I/O readers and writers. Additionally, great lengths are taken to ensure that the entire contents are never required to be entirely resident in memory all at once.

Reading an archive

extern crate tar;

use std::io::prelude::*;
use std::fs::File;
use tar::Archive;

fn main() {
    let file = File::open("foo.tar").unwrap();
    let mut a = Archive::new(file);

    for file in a.entries().unwrap() {
        // Make sure there wasn't an I/O error
        let mut file = file.unwrap();

        // Inspect metadata about the file
        println!("{:?}", file.header().path().unwrap());
        println!("{}", file.header().size().unwrap());

        // files implement the Read trait
        let mut s = String::new();
        file.read_to_string(&mut s).unwrap();
        println!("{}", s);
    }
}

Writing an archive

extern crate tar;

use std::io::prelude::*;
use std::fs::File;
use tar::Builder;

fn main() {
    let file = File::create("foo.tar").unwrap();
    let mut a = Builder::new(file);

    a.append_path("file1.txt").unwrap();
    a.append_file("file2.txt", &mut File::open("file3.txt").unwrap()).unwrap();
}
