Expand description

UDP server for receiving OpenIGTLink messages

Listens for incoming datagrams on a specific port.

§Examples

use openigtlink_rust::io::UdpServer;
use openigtlink_rust::protocol::types::TransformMessage;
use openigtlink_rust::protocol::message::IgtlMessage;

let server = UdpServer::bind("0.0.0.0:18944")?;

loop {
    let (msg, sender) = server.receive::<TransformMessage>()?;
    println!("Received from {}", sender);

    // Echo back
    let response = IgtlMessage::new(msg.content, "Server")?;
    server.send_to(&response, sender)?;

}
