squashfuse-rs

使用 fuser 和 backhand 包在 rust 中实现的 SquashFS 的 FUSE 实现！

受一个名为 squashfuse 的 C 库的启发 https://github.com/vasi/squashfuse/tree/master

欢迎提交 PR，我对 SquashFS 和 FUSE 并不十分了解，所以如果有更好的方法，请告诉我！

示例用法来自 appimage-type2-runtime-rs

fn fusefs_main(offset: u64, mountpoint: &Path, archive_path: &Path) -> anyhow::Result<()> {
    let reader = BufReader::new(File::open(&archive_path)?);
    let fs = squashfuse_rs::SquashfsFilesystem::new(
        backhand::FilesystemReader::from_reader_with_offset(reader, offset)?,
    );
    let mount_options = vec![
        fuser::MountOption::FSName("squashfuse".to_string()),
        fuser::MountOption::RO,
    ];
    match fuser::mount2(fs, mountpoint, &mount_options) {
        Ok(()) => {
            println!("Mounted {:?} at {:?}", archive_path, mountpoint);
            Ok(())
        }
        Err(err) => Err(anyhow::anyhow!("Failed to mount: {}", err)),
}
