Crate ext4

This crate can load ext4 filesystems, letting you read metadata and files from them.

Example

let mut block_device = std::io::BufReader::new(std::fs::File::open("/dev/sda1").unwrap());
let mut superblock = ext4::SuperBlock::new(&mut block_device).unwrap();
let target_inode_number = superblock.resolve_path("/etc/passwd").unwrap().inode;
let inode = superblock.load_inode(target_inode_number).unwrap();
let passwd_reader = superblock.open(&inode).unwrap();

Note: normal users can't read /dev/sda1 by default, as it would allow them to read any file on the filesystem. You can grant yourself temporary access with sudo setfacl -m u:${USER}:r /dev/sda1, if you so fancy. This will be lost at reboot.
