You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: main.rs
    path of file: ./repos/mirrord/mirrord/layer/tests/apps/recv_from/src
    
    the code of the file until where you have to start completion: use std::{mem::MaybeUninit, net::SocketAddr};

use socket2::{Domain, Socket, Type};

fn main() {
    let address: SocketAddr = "1.2.3.4:4367".parse().unwrap();

    let socket = Socket::new(Domain::IPV4, Type::DGRAM, None).expect("Failed to create socket");

    socke
    
fn main() {
    let address: SocketAddr = "1.2.3.4:4367".parse().unwrap();

    let socket = Socket::new(Domain::IPV4, Type::DGRAM, None).expect("Failed to create socket");

    socket
        .connect(&address.into())
        .expect("Failed to connect to socket");

    let data = "Hello, world!";

    socket.send(data.as_bytes()).expect("Failed to send query");

    let mut response = [MaybeUninit::<u8>::uninit(); 1024];
    let (len, source_address) = socket
        .recv_from(&mut response)
        .expect("Failed to receive response");

    let response = response
        .get(..len)
        .unwrap()
        .iter()
        .map(|b| unsafe { b.assume_init() })
        .collect::<Vec<u8>>();

    assert_eq!(
        String::from_utf8(response).expect("Failed to parse response"),
        "Hello, world!"
    );

    assert_eq!(
        source_address.as_socket_ipv4().unwrap().to_string(),
        "1.2.3.4:4367"
    );
}
