# udev
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.
* [Documentation](http://docs.rs/udev/)
## 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](https://github.com/dcuddeback/libudev-sys#cross-compiling).
## Usage
Add `udev` as a dependency in `Cargo.toml`:
```toml
[dependencies]
udev = "^0.9.1"
```
If you plan to support operating systems other than Linux, you'll need to add `udev` as a
target-specific dependency:
```toml
[target.x86_64-unknown-linux-gnu.dependencies]
udev = "^0.9.1"
```
Import the `udev` crate.
```rust
extern crate udev;
fn main() {
let mut enumerator = udev::Enumerator::new().unwrap();
enumerator.match_subsystem("tty").unwrap();
for device in enumerator.scan_devices().unwrap() {
println!("found device: {:?}", device.syspath());
}
}
```
