Struct UdpSocket 

pub struct UdpSocket { /* private fields */ }

Implementations

impl UdpSocket

pub fn from_std(socket: UdpSocket) -> Result<Self>

Creates a new UDP socket from a previously created std::net::UdpSocket

pub fn bind<A: ToSocketAddrs>(addr: A) -> Result<Self>

create a new UDP socket and attempt to bind to addr

pub fn set_nonblocking(&self, nonblocking: bool) -> Result<()>

sets nonblocking mode

pub fn set_broadcast(&self, broadcast: bool) -> Result<()>

sets the value of SO_BROADCAST for this socket

pub fn connect<A: ToSocketAddrs>(&self, addrs: A) -> Result<()>

pub fn join_multicast_v4( &self, multiaddr: Ipv4Addr, interface: Ipv4Addr, ) -> Result<()>

pub fn join_multicast_v6( &self, multiaddr: &Ipv6Addr, interface: u32, ) -> Result<()>

pub fn leave_multicast_v4( &self, multiaddr: Ipv4Addr, interface: Ipv4Addr, ) -> Result<()>

pub fn leave_multicast_v6( &self, multiaddr: &Ipv6Addr, interface: u32, ) -> Result<()>

pub fn set_multicast_loop_v4(&self, on: bool) -> Result<()>

pub fn set_multicast_loop_v6(&self, on: bool) -> Result<()>

pub fn send_to(&self, buf: &[u8], target: SocketAddr) -> Result<usize>

Sends data on the socket to the given address. On success, returns the number of bytes written.

calls underlying tokio send_to

pub fn send(&self, buf: &[u8]) -> Result<usize>

Sends data on the socket to the remote address that the socket is connected to.

See tokio send

pub fn recv_from(&self, buf: &mut [u8]) -> Result<(usize, SocketAddr)>

Receives a single datagram message on the socket. On success, returns the number of bytes read and the origin.

See tokio recv_from

pub fn recv(&self, buf: &mut [u8]) -> Result<usize>

Receives a single datagram message on the socket from the remote address to which it is connected. On success, returns the number of bytes read.

See tokio recv

pub fn send_mmsg<B: AsPtr<u8>>( &self, state: &UdpState, transmits: &[Transmit<B>], ) -> Result<usize, Error>

Calls syscall sendmmsg. With a given state configured GSO and transmits with information on the data and metadata about outgoing packets.

pub fn send_msg<B: AsPtr<u8>>( &self, state: &UdpState, transmits: Transmit<B>, ) -> Result<usize>

Calls syscall sendmsg. With a given state configured GSO and transmit with information on the data and metadata about outgoing packet.

pub fn recv_mmsg( &self, bufs: &mut [IoSliceMut<'_>], meta: &mut [RecvMeta], ) -> Result<usize>

async version of recvmmsg

pub fn recv_msg(&self, buf: &mut [u8]) -> Result<RecvMeta>

recv_msg is similar to recv_from but returns extra information about the packet in RecvMeta.

pub fn local_addr(&self) -> Result<SocketAddr>

Returns local address this socket is bound to.

Trait Implementations

impl AsRawFd for UdpSocket

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl Debug for UdpSocket

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl IntoRawFd for UdpSocket

fn into_raw_fd(self) -> RawFd
