Read

let mut file = File::open("archive.cpio").unwrap();
let mut archive = ArchiveReader::<NewcHeader>::from_reader_with_offset(&mut file, 0).unwrap();

// extract bytes from all in archive
for object in &archive.objects.inner {
    let mut out = OpenOptions::new()
        .write(true)
        .create(true)

}

Write

let file = File::create("archive.cpio").unwrap();
let mut writer = ArchiveWriter::<NewcHeader>::new(Box::new(file));

// A
let a_data = "a\n".as_bytes();
let a_header = Header { name: "a".to_string(), ..Header::default()};
writer.push_file(Cursor::new(a_data), a_header).unwrap();

// write to archive
writer.write().unwrap();
