Struct UdpSocket 

pub struct UdpSocket { /* private fields */ }

UDP socket type / UDP套接字类型

Provides async UDP send and receive operations. 提供异步UDP发送和接收操作。

Example / 示例

use hiver_runtime::io::UdpSocket;

async fn echo_server() -> std::io::Result<()> {
    let socket = UdpSocket::bind("127.0.0.1:8080").await?;
    println!("UDP server listening on 127.0.0.1:8080");

    let mut buf = [0u8; 1024];
    loop {
        let (n, peer) = socket.recv_from(&mut buf).await?;
        socket.send_to(&buf[..n], &peer).await?;
    }
}

Implementations

impl UdpSocket

pub fn bind(addr: &str) -> BindUdpFuture

Bind a new UDP socket to the specified address 将新的UDP套接字绑定到指定地址

Example / 示例

use hiver_runtime::io::UdpSocket;

async fn bind_server() -> std::io::Result<()> {
    let socket = UdpSocket::bind("127.0.0.1:8080").await?;
    Ok(())
}

pub fn recv_from<'a, 'b>( &'a mut self, buf: &'b mut [u8], ) -> RecvFromFuture<'a, 'b>

Receive data from the socket 从套接字接收数据

Returns the number of bytes received and the peer address. 返回接收的字节数和对端地址。

pub fn send_to<'a, 'b>( &'a mut self, buf: &'b [u8], addr: SocketAddr, ) -> SendToFuture<'a, 'b>

Send data to the specified address 向指定地址发送数据

Returns the number of bytes sent. 返回发送的字节数。

pub fn connect(&mut self, addr: SocketAddr) -> ConnectUdpFuture

Connect the socket to a remote address 将套接字连接到远程地址

This filters incoming datagrams to only receive from this address. 这会过滤传入的数据报，只接收来自此地址的数据。

impl AsRawFd for UdpSocket

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.
