# artnet_protocol


Contains the [ArtCommand](struct.ArtCommand.html) enum which holds the entire ArtNet protocol v4, as per [https://artisticlicence.com/WebSiteMaster/User%20Guides/art-net.pdf](https://artisticlicence.com/WebSiteMaster/User%20Guides/art-net.pdf)

```rust
use artnet_protocol::*;
use std::net::{UdpSocket, ToSocketAddrs};

let socket = UdpSocket::bind(("0.0.0.0", 6454)).unwrap();
let broadcast_addr = ("255.255.255.255", 6454).to_socket_addrs().unwrap().next().unwrap();
socket.set_broadcast(true).unwrap();
let buff = ArtCommand::Poll(Poll::default()).write_to_buffer().unwrap();
socket.send_to(&buff, &broadcast_addr).unwrap();

loop {
    let mut buffer = [0u8; 1024];
    let (length, addr) = socket.recv_from(&mut buffer).unwrap();
    let command = ArtCommand::from_buffer(&buffer[..length]).unwrap();

    println!("Received {:?}", command);
    match command {
        ArtCommand::Poll(poll) => {
            // This will most likely be our own poll request, as this is broadcast to all devices on the network
        },
        ArtCommand::PollReply(reply) => {
            // This is an ArtNet node on the network. We can send commands to it like this:
            let command = ArtCommand::Output(Output {
                length: 5, // must match your data.len()
                data: vec![1, 2, 3, 4, 5], // The data we're sending to the node
                ..Output::default()
            });
            let bytes = command.write_to_buffer().unwrap();
            socket.send_to(&bytes, &addr).unwrap();
        },
        _ => {}
    }
}
