Crate abootimg_oxide

A parser for Android boot image headers (e.g. boot.img or vendor_boot.img).

This can be used to extract or patch e.g. the kernel or ramdisk.

Byte array fields ([u8; N]) can be used as null-terminated strings.

Examples

use std::fs::File;
use abootimg_oxide::{BufReader, Header};

let mut r = BufReader::new(File::open("boot_a.img").unwrap());
let hdr = Header::parse(&mut r).unwrap();
println!("{hdr:#?}");

// Extract the kernel
use std::io::{self, BufWriter, Read, Seek, SeekFrom};

let mut w = BufWriter::new(File::create("boot_a_kernel").unwrap());
let r = r.get_mut();
r.seek(SeekFrom::Start(hdr.kernel_position() as u64))
    .unwrap();
io::copy(&mut r.take(hdr.kernel_size() as u64), w.get_mut()).unwrap();
