Crate sys_mount

source ·
Expand description

High level abstraction over the mount and umount2 system calls.

If the loop feature is enabled (default), additionally supports creating loopback devices automatically when mounting an iso or squashfs file.


extern crate sys_mount;

use std::process::exit;
use sys_mount::{

fn main() {
    // Fetch a list of supported file systems.
    // When mounting, a file system will be selected from this.
    let supported = SupportedFilesystems::new().unwrap();

    // Attempt to mount the src device to the dest directory.
    let mount_result = Mount::builder()
        .mount("/dev/sda1", "/home");

    match mount_result {
        Ok(mount) => {
            // Make the mount temporary, so that it will be unmounted on drop.
            let mount = mount.into_unmount_drop(UnmountFlags::DETACH);
            // Do thing with the mounted device.
        Err(why) => {
            eprintln!("failed to mount device: {}", why);

Builder API for mounting devices
Flags which may be specified when mounting a file system.
An abstraction that will ensure that temporary mounts are dropped in reverse.

Defines how the file system type should be derived for a mount – auto or manual
