Struct cap_async_std::net::UdpSocket

pub struct UdpSocket { /* fields omitted */ }

A UDP socket.

This corresponds to async_std::net::UdpSocket.

Note that this UdpSocket has no bind, connect, or send_to methods. To create a UdpSocket bound to an address or to send a message to an address, you must first obtain a Pool permitting the address, and then call Pool::bind_udp_socket, or Pool::connect_udp_socket, or Pool::send_to_udp_socket_addr.

Implementations

impl UdpSocket

pub fn from_std(std: UdpSocket, _: AmbientAuthority) -> Self

Constructs a new instance of Self from the given async_std::net::UdpSocket.

Ambient Authority

async_std::net::UdpSocket is not sandboxed and may access any address that the host process has access to.

pub fn set_ttl(&self, ttl: u32) -> Result<()>

Sets the value for the IP_TTL option on this socket.

This corresponds to async_std::net::UdpSocket::set_ttl.

pub fn ttl(&self) -> Result<u32>

Gets the value of the IP_TTL option for this socket.

This corresponds to async_std::net::UdpSocket::ttl.

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

Executes an operation of the IP_ADD_MEMBERSHIP type.

This corresponds to async_std::net::UdpSocket::join_multicast_v4.

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

Executes an operation of the IPV6_ADD_MEMBERSHIP type.

This corresponds to async_std::net::UdpSocket::join_multicast_v6.

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

Executes an operation of the IP_DROP_MEMBERSHIP type.

This corresponds to async_std::net::UdpSocket::leave_multicast_v4.

This corresponds to async_std::net::UdpSocket::recv.

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 FromRawFd for UdpSocket

unsafe fn from_raw_fd(fd: RawFd) -> Self

Constructs a new instance of Self from the given raw file descriptor.

impl IntoRawFd for UdpSocket

fn into_raw_fd(self) -> RawFd
