&self,
multiaddr: &Ipv4Addr,
interface: &Ipv4Addr
) -> Result<()>[−]
&self,
multiaddr: &Ipv4Addr,
interface: &Ipv4Addr
) -> Result<()>
Executes an operation of the IP_ADD_MEMBERSHIP type.
This function specifies a new multicast group for this socket to join.
The address must be a valid multicast address, and interface is the
address of the local interface with which the system should join the
multicast group. If it's equal to INADDR_ANY then an appropriate
interface is chosen by the system.
fn join_multicast_v6(&self, multiaddr: &Ipv6Addr, interface: u32) -> Result<()>[−]
Executes an operation of the IPV6_ADD_MEMBERSHIP type.
This function specifies a new multicast group for this socket to join.
The address must be a valid multicast address, and interface is the
index of the interface to join/leave (or 0 to indicate any interface).
fn leave_multicast_v4(
&self,
multiaddr: &Ipv4Addr,
interface: &Ipv4Addr
) -> Result<()>[−]
&self,
multiaddr: &Ipv4Addr,
interface: &Ipv4Addr
) -> Result<()>
Executes an operation of the IP_DROP_MEMBERSHIP type.
For more information about this option, see
join_multicast_v4.
fn leave_multicast_v6(&self, multiaddr: &Ipv6Addr, interface: u32) -> Result<()>[−]
Executes an operation of the IPV6_DROP_MEMBERSHIP type.
For more information about this option, see
join_multicast_v6.
fn set_read_timeout_ms(&self, val: Option<u32>) -> Result<()>[−]
Sets the SO_RCVTIMEO option for this socket.
This option specifies the timeout, in milliseconds, of how long calls to
this socket's read function will wait before returning a timeout. A
value of None means that no read timeout should be specified and
otherwise Some indicates the number of milliseconds for the timeout.
fn set_read_timeout(&self, val: Option<Duration>) -> Result<()>[−]
Sets the SO_RCVTIMEO option for this socket.
This option specifies the timeout of how long calls to this socket's
read function will wait before returning a timeout. A value of None
means that no read timeout should be specified and otherwise Some
indicates the number of duration of the timeout.
fn read_timeout_ms(&self) -> Result<Option<u32>>[−]
Gets the value of the SO_RCVTIMEO option for this socket.
For more information about this option, see set_read_timeout_ms.
fn read_timeout(&self) -> Result<Option<Duration>>[−]
Gets the value of the SO_RCVTIMEO option for this socket.
For more information about this option, see set_read_timeout.
fn set_write_timeout_ms(&self, val: Option<u32>) -> Result<()>[−]
Sets the SO_SNDTIMEO option for this socket.
This option specifies the timeout, in milliseconds, of how long calls to
this socket's write function will wait before returning a timeout. A
value of None means that no read timeout should be specified and
otherwise Some indicates the number of milliseconds for the timeout.
fn set_write_timeout(&self, val: Option<Duration>) -> Result<()>[−]
Sets the SO_SNDTIMEO option for this socket.
This option specifies the timeout of how long calls to this socket's
write function will wait before returning a timeout. A value of None
means that no read timeout should be specified and otherwise Some
indicates the duration of the timeout.
fn write_timeout_ms(&self) -> Result<Option<u32>>[−]
Gets the value of the SO_SNDTIMEO option for this socket.
For more information about this option, see set_write_timeout_ms.
fn write_timeout(&self) -> Result<Option<Duration>>[−]
Gets the value of the SO_SNDTIMEO option for this socket.
For more information about this option, see set_write_timeout.
fn take_error(&self) -> Result<Option<Error>>[−]
Get the value of the SO_ERROR option on this socket.
This will retrieve the stored error in the underlying socket, clearing the field in the process. This can be useful for checking errors between calls.
fn connect<A: ToSocketAddrs>(&self, addr: A) -> Result<()>[−]
Connects this UDP socket to a remote address, allowing the send and
recv syscalls to be used to send data and also applies filters to only
receive data from the specified address.
fn send(&self, buf: &[u8]) -> Result<usize>[−]
Sends data on the socket to the remote address to which it is connected.
The connect method will connect this socket to a remote address. This
method will fail if the socket is not connected.
fn recv(&self, buf: &mut [u8]) -> Result<usize>[−]
Receives data on the socket from the remote address to which it is connected.
The connect method will connect this socket to a remote address. This
method will fail if the socket is not connected.
fn set_nonblocking(&self, nonblocking: bool) -> Result<()>[−]
Moves this UDP socket into or out of nonblocking mode.

TcpStreamExt::set_nonblocking.
