Rust std::net::UdpSocket没有名为recv_from的方法

use std::net::UdpSocket;

fn main() {
    let socket = UdpSocket::bind("127.0.0.1:8080").expect("Failed to bind socket");
    let mut buffer = [0; 1024];

    loop {
        match socket.recv(&mut buffer) {
            Ok(received) => {
                println!("Received {} bytes: {:?}", received, &buffer[..received]);
            }
            Err(e) => {
                eprintln!("Failed to receive data: {}", e);
                break;
            }
        }
    }
}

use std::net::{UdpSocket, SocketAddr};
