Crate tun_rs 

Example:

use tun_rs::DeviceBuilder;
let dev = DeviceBuilder::new()
            .name("utun7")
            .ipv4("10.0.0.12", 24, None)
            .ipv6("CDCD:910A:2222:5498:8475:1111:3900:2021", 64)
            .mtu(1400)
            .build_sync()
            .unwrap();
let mut buf = [0;65535];
loop {
    let len = dev.recv(&mut buf).unwrap();
    println!("buf= {:?}",&buf[..len]);
}

Example IOS/Android/… :

#[cfg(unix)]
{
    use tun_rs::SyncDevice;
    // use PacketTunnelProvider/VpnService create tun fd
    let fd = 7799;
    let dev = unsafe{SyncDevice::from_fd(fd).unwrap()};
    let mut buf = [0;65535];
    loop {
        let len = dev.recv(&mut buf).unwrap();
        println!("buf= {:?}",&buf[..len]);
    }
}
