rsmount
⚠️ WARNING: This library is still in development, thus not yet suitable for use in production.
The rsmount
library is a safe Rust wrapper around util-linux/libmount
.
rsmount
allows users to, among other things:
- mount devices on an operating system’s file hierarchy,
- list/manage mount points in
/proc/<pid>/mountinfo
, - consult the system’s swap usage from /proc/swaps,
- compose/edit /etc/fstab, the file describing all devices an OS should mount at boot.
- etc.
Usage
This crate requires libmount
version 2.39.2
or later.
Add the following to your Cargo.toml
:
[dependencies]
rsmount = "0.1.0"
Then install the system packages below before running cargo build
:
util-linux
: to generate Rust bindings fromlibmount
's header files.libclang
: to satisfy the dependency ofbindgen
onlibclang
.pkg-config
: to detect system libraries.
Read the installation instructions below to install the required dependencies on your system.
Example
In this example we mount a disk on /mnt/backup
.
use rsmount::core::device::BlockDevice;
use rsmount::core::flags::MountFlag;
use rsmount::core::fs::FileSystem;
use rsmount::mount::Mount;
fn main() -> rsmount::Result<()> {
// Configure the `Mount` struct.
let block_device: BlockDevice = "/dev/vda".parse()?;
let mut mount = Mount::builder()
// Device to mount.
.source(block_device.into())
// Location of the mount point in the file tree.
.target("/mnt/backup")
// Do not allow writing to the file system while it is mounted.
.mount_flags(vec![MountFlag::ReadOnly])
// Gives a hint about the file system used by the device (optional).
.file_system(FileSystem::Ext4)
.build()?;
// Mount `/dev/vda` at `/mnt/backup`.
mount.mount_device()?;
Ok(())
}
