UnixSocket编程双工通信例子

Arduino极客

客户端发送66(int32),服务端判断是奇偶并返回Boolean

use std::{io::{Read, Write}, os::unix::net::{UnixListener, UnixStream}};

#[derive(serde::Serialize, serde::Deserialize, Debug)]
enum Message {
    I32(i32),
    Bool(bool)
}

const UNIX_SOCK_ADDR: &str = "/home/w/temp/my_sock.sock11";

#[test]
fn unix_socket_server() -> Result<(), Box<dyn std::error::Error>> {
    let listener = UnixListener::bind(UNIX_SOCK_ADDR)?;
    for mut stream in listener.incoming().flatten() {
        //stream.recv_vectored_with_ancillary(bufs, ancillary);
        let mut read_buffer = Vec::new();
        stream.read_to_end(&mut read_buffer)?;
        let request: Message = bincode::deserialize(&read_buffer[..])?;
        println!("Server Incomming Request: {:?}", request);
        let response = match request {
            Message::I32(int) => Message::Bool(int % 2 == 1),
            _ => panic!("unsupported message type")
        };
        println!("Server Preprare Reponse: {:?}", response);
        // stream.write(&bincode::serialize(&response)?)?;
        // stream.flush()?;
        stream.shutdown(std::net::Shutdown::Both);
    }
    Ok(())
}

#[test]
fn unix_socket_client() -> Result<(), Box<dyn std::error::Error>> {
    let mut stream = UnixStream::connect(UNIX_SOCK_ADDR)?;
    let request = Message::I32(66);
    stream.write(&bincode::serialize(&request)?)?;
    stream.flush()?;
    Ok(())
