send a binary message to a udp server in rust

To send a binary message to a UDP server in Rust, you first need to create a UDP socket and bind it to a port. Once the socket is bound, you can use the send_to function to send a binary message to the server.

Here's some sample code that demonstrates how to create a UDP socket and send a binary message to a server:

main.rs
use std::net::UdpSocket;

fn main() -> std::io::Result<()> {
    // Bind socket to a port
    let socket = UdpSocket::bind("127.0.0.1:8080")?;

    // Server address and port
    let server_address = "127.0.0.1:8888";

    // Binary data to be sent
    let message = &[0x01, 0x02, 0x03, 0x04];

    // Send binary message to server
    socket.send_to(message, server_address)?;

    Ok(())
}

In this example, we create a UDP socket and bind it to port 8080. We then specify the address and port of the server that we want to send the binary message to (127.0.0.1:8888). Finally, we define the binary message that we want to send ([0x01, 0x02, 0x03, 0x04]) and pass it to the send_to function along with the server address.

Note that we're using the std::net::UdpSocket module to create the socket and send the message. In addition, we're using the send_to function to send the binary message to the server. This function takes the binary message and the server address as arguments.

That should be enough to get you started with sending binary messages to a UDP server in Rust!
