Using the Crate in Your Rust Project

To use min-tun in your Rust project, you need to include it as a dependency in your Cargo.toml:

After adding the dependency, you can use the crate in your code. Here's a simple example:

// main.rs

fn main() {
    match min_tun::find_min_available_tun() {
        Some(tun_name) => println!("Minimum available tun device: {}", tun_name),
        None => println!("Could not find an available tun device"),
    }
}

To build and run your project, execute:

cargo build
cargo run
