artnet_protocol

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

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

let socket = UdpSocket::bind(("0.0.0.0", 6454)).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();

    println!("Received {:?}", command);
    match command {
        ArtCommand::Poll(poll) => {

        },
        ArtCommand::PollReply(reply) => {

                length: 5, // must match your data.len()
                data: vec![1, 2, 3, 4, 5], // The data we're sending to the node
                ..Output::default()
