TAPD interfaces

Usage

First, add the following to your Cargo.toml:

[dependencies]
tapd = "0.1"

Example

The following example creates and configures a TAP interface and starts reading packets from it.

use std::{env::args, io::IsTerminal};
use tapd::{pipe_std, pipe_tun};

#[tokio::main(worker_threads = 2)]
async fn main() {
    let mut argv = args();
    let app = argv.next().unwrap();
    match argv.len() {
        2 => pipe_tun(&argv.next().unwrap(), &argv.next().unwrap()).await,
        1 => {
            let a = std::io::stdin();
            let b = std::io::stdout();
            if !a.is_terminal() && !b.is_terminal() {
                pipe_std(&argv.next().unwrap()).await
            }
        }
        _ => {}
    }
    eprintln!("Usage: {app:?} [dev1 dev2 | dev]");
}

Linux

You will need the tun module to be loaded and root is required to create interfaces.
