Libudev
This crate provides a safe wrapper around the native libudev library. It applies the RAII pattern
and Rust lifetimes to ensure safe usage of all libudev functionality. The RAII pattern ensures
that all acquired resources are released when they're no longer needed, and Rust lifetimes ensure
that resources are released in a proper order.
Dependencies
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.
Cross-Compiling
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.
Usage
Add libudev as a dependency in Cargo.toml:
[dependencies]
libudev = "0.2"
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 = "0.2"
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());
}
}
