Struct ArchiveReader

pub struct ArchiveReader<'b, C: CpioHeader> {
    pub reader: Box<dyn ReadSeek + 'b>,
    pub objects: Objects<C>,
}

Read cpio Archive and extract data

Example

Read archive.cpio and extract data.

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)
       .open(object.header.as_header().name)
       .unwrap();
    archive.reader.extract_data(object, &mut out).unwrap();
}
