This crate provides a safe wrapper around the native libudev library.

• Documentation

In order to use the libudev crate, you must have a Linux system with the libudev library installed where it can be found by pkg-config. To install libudev on Debian-based Linux distributions, execute the following command:

sudo apt-get install libudev-dev

libudev is a Linux-specific package. It is not available for Windows, OS X, or other operating systems.

The libudev crate can be used when cross-compiling to a foreign target. Details on how to cross-compile libudev are explained in the libudev-sys crate's README.

Add libudev as a dependency in Cargo.toml:

[dependencies]
libudev = "0.3"

If you plan to support operating systems other than Linux, you'll need to add libudev as a target-specific dependency:

[target.x86_64-unknown-linux-gnu.dependencies]
libudev = "0.3"

Import the libudev crate. The starting point for nearly all libudev functionality is to create a context object.

extern crate libudev;

fn main() {
    let context = libudev::Context::new().unwrap();
    let mut enumerator = libudev::Enumerator::new(&context).unwrap();

    enumerator.match_subsystem("tty").unwrap();

    for device in enumerator.scan_devices().unwrap() {
        println!("found device: {:?}", device.syspath());
    }
}
