[−][src]Struct async_coap::datagram::AllowStdUdpSocket
A wrapper around std::net::UdpSocket
that implements AsyncDatagramSocket
.
This can be used to allow the standard rust UdpSocket
(which doesn't provide an
asynchronous API) to be used in an asynchronous fashion, similar to [futures-preview::io::AllowStdio
].
Note that by default this wrapper will block execution whenever one of the poll
methods is
called (An exception is any instance created with AllowStdUdpSocket::bind
).
You can fake true asynchronous behavior by calling set_nonblocking(true)
or
set_read_timeout()
. In the case where a UDP message is not received when polled (or it
times out waiting for a response), a futures_timer::Delay
is used to schedule an appropriate
duration (set via set_async_poll_interval()
) after which it can try again. This is obviously
sub-optimal, but that's the best that can be offered without becoming intrusive.
As such, it is really intended to be a convenience stop-gap to get things up and running
quickly. For production code, you would want to use a AsyncDatagramSocket
wrapper around
something truly asynchronous, like [tokio-udp::UdpSocket
].
Methods
impl AllowStdUdpSocket
[src]
pub fn from_std(udp_socket: UdpSocket) -> AllowStdUdpSocket
[src]
Upgrades the given std::net::UdpSocket
to an instance of AllowStdUdpSocket
.
Note that no operations are performed on udp_socket
by this method. It is recommended
that you call std::net::UdpSocket::set_nonblocking
on the socket before using this
method. See the documentation for AllowStdUdpSocket
for more information.
pub fn bind<A>(addr: A) -> Result<AllowStdUdpSocket> where
A: ToSocketAddrs,
[src]
A: ToSocketAddrs,
Analog to std::net::UdpSocket::bind
to an instance of AllowStdUdpSocket
.
If addr
is successfully resolved, the underlying UdpSocket
will already be
configured in a non-blocking operation mode.
pub fn set_async_poll_interval(
&mut self,
dur: Option<Duration>
) -> Option<Duration>
[src]
&mut self,
dur: Option<Duration>
) -> Option<Duration>
Changes the async poll interval for this socket, returning the previous value.
A value of None
indicates that no timed polling should be performed.
The default value is
Some(DEFAULT_ASYNC_POLL_INTERVAL)
,
or 30ms.
Methods from Deref<Target = UdpSocket>
pub fn recv_from(&self, buf: &mut [u8]) -> Result<(usize, SocketAddr), Error>
1.0.0[src]
Receives a single datagram message on the socket. On success, returns the number of bytes read and the origin.
The function must be called with valid byte array buf
of sufficient size to
hold the message bytes. If a message is too long to fit in the supplied buffer,
excess bytes may be discarded.
Examples
use std::net::UdpSocket; let socket = UdpSocket::bind("127.0.0.1:34254").expect("couldn't bind to address"); let mut buf = [0; 10]; let (number_of_bytes, src_addr) = socket.recv_from(&mut buf) .expect("Didn't receive data"); let filled_buf = &mut buf[..number_of_bytes];
pub fn peek_from(&self, buf: &mut [u8]) -> Result<(usize, SocketAddr), Error>
1.18.0[src]
Receives a single datagram message on the socket, without removing it from the queue. On success, returns the number of bytes read and the origin.
The function must be called with valid byte array buf
of sufficient size to
hold the message bytes. If a message is too long to fit in the supplied buffer,
excess bytes may be discarded.
Successive calls return the same data. This is accomplished by passing
MSG_PEEK
as a flag to the underlying recvfrom
system call.
Do not use this function to implement busy waiting, instead use libc::poll
to
synchronize IO events on one or more sockets.
Examples
use std::net::UdpSocket; let socket = UdpSocket::bind("127.0.0.1:34254").expect("couldn't bind to address"); let mut buf = [0; 10]; let (number_of_bytes, src_addr) = socket.peek_from(&mut buf) .expect("Didn't receive data"); let filled_buf = &mut buf[..number_of_bytes];
pub fn send_to<A>(&self, buf: &[u8], addr: A) -> Result<usize, Error> where
A: ToSocketAddrs,
1.0.0[src]
A: ToSocketAddrs,
Sends data on the socket to the given address. On success, returns the number of bytes written.
Address type can be any implementor of ToSocketAddrs
trait. See its
documentation for concrete examples.
It is possible for addr
to yield multiple addresses, but send_to
will only send data to the first address yielded by addr
.
This will return an error when the IP version of the local socket
does not match that returned from ToSocketAddrs
.
See issue #34202 for more details.
Examples
use std::net::UdpSocket; let socket = UdpSocket::bind("127.0.0.1:34254").expect("couldn't bind to address"); socket.send_to(&[0; 10], "127.0.0.1:4242").expect("couldn't send data");
pub fn peer_addr(&self) -> Result<SocketAddr, Error>
[src]
udp_peer_addr
)Returns the socket address of the remote peer this socket was connected to.
Examples
#![feature(udp_peer_addr)] use std::net::{Ipv4Addr, SocketAddr, SocketAddrV4, UdpSocket}; let socket = UdpSocket::bind("127.0.0.1:34254").expect("couldn't bind to address"); socket.connect("192.168.0.1:41203").expect("couldn't connect to address"); assert_eq!(socket.peer_addr().unwrap(), SocketAddr::V4(SocketAddrV4::new(Ipv4Addr::new(192, 168, 0, 1), 41203)));
If the socket isn't connected, it will return a NotConnected
error.
#![feature(udp_peer_addr)] use std::net::UdpSocket; let socket = UdpSocket::bind("127.0.0.1:34254").expect("couldn't bind to address"); assert_eq!(socket.peer_addr().unwrap_err().kind(), ::std::io::ErrorKind::NotConnected);
pub fn local_addr(&self) -> Result<SocketAddr, Error>
1.0.0[src]
Returns the socket address that this socket was created from.
Examples
use std::net::{Ipv4Addr, SocketAddr, SocketAddrV4, UdpSocket}; let socket = UdpSocket::bind("127.0.0.1:34254").expect("couldn't bind to address"); assert_eq!(socket.local_addr().unwrap(), SocketAddr::V4(SocketAddrV4::new(Ipv4Addr::new(127, 0, 0, 1), 34254)));
pub fn try_clone(&self) -> Result<UdpSocket, Error>
1.0.0[src]
Creates a new independently owned handle to the underlying socket.
The returned UdpSocket
is a reference to the same socket that this
object references. Both handles will read and write the same port, and
options set on one socket will be propagated to the other.
Examples
use std::net::UdpSocket; let socket = UdpSocket::bind("127.0.0.1:34254").expect("couldn't bind to address"); let socket_clone = socket.try_clone().expect("couldn't clone the socket");
pub fn set_read_timeout(&self, dur: Option<Duration>) -> Result<(), Error>
1.4.0[src]
Sets the read timeout to the timeout specified.
If the value specified is None
, then read
calls will block
indefinitely. An Err
is returned if the zero Duration
is
passed to this method.
Platform-specific behavior
Platforms may return a different error code whenever a read times out as
a result of setting this option. For example Unix typically returns an
error of the kind WouldBlock
, but Windows may return TimedOut
.
Examples
use std::net::UdpSocket; let socket = UdpSocket::bind("127.0.0.1:34254").expect("couldn't bind to address"); socket.set_read_timeout(None).expect("set_read_timeout call failed");
An Err
is returned if the zero Duration
is passed to this
method:
use std::io; use std::net::UdpSocket; use std::time::Duration; let socket = UdpSocket::bind("127.0.0.1:34254").unwrap(); let result = socket.set_read_timeout(Some(Duration::new(0, 0))); let err = result.unwrap_err(); assert_eq!(err.kind(), io::ErrorKind::InvalidInput)
pub fn set_write_timeout(&self, dur: Option<Duration>) -> Result<(), Error>
1.4.0[src]
Sets the write timeout to the timeout specified.
If the value specified is None
, then write
calls will block
indefinitely. An Err
is returned if the zero Duration
is
passed to this method.

pub fn set_multicast_ttl_v4(&self, multicast_ttl_v4: u32) -> Result<(), Error>
1.9.0[src]
Sets the value of the IP_MULTICAST_TTL
option for this socket.

pub fn join_multicast_v4(
&self,
multiaddr: &Ipv4Addr,
interface: &Ipv4Addr
) -> Result<(), Error>
1.9.0[src]
&self,
multiaddr: &Ipv4Addr,
interface: &Ipv4Addr
) -> Result<(), Error>
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.
pub fn join_multicast_v6(
&self,
multiaddr: &Ipv6Addr,
interface: u32
) -> Result<(), Error>
1.9.0[src]
&self,
multiaddr: &Ipv6Addr,
interface: u32
) -> Result<(), Error>
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).
pub fn leave_multicast_v4(
&self,
multiaddr: &Ipv4Addr,
interface: &Ipv4Addr
) -> Result<(), Error>
1.9.0[src]
&self,
multiaddr: &Ipv4Addr,
interface: &Ipv4Addr
) -> Result<(), Error>
Executes an operation of the IP_DROP_MEMBERSHIP
type.
For more information about this option, see
join_multicast_v4
.
pub fn leave_multicast_v6(
&self,
multiaddr: &Ipv6Addr,
interface: u32
) -> Result<(), Error>
1.9.0[src]
&self,
multiaddr: &Ipv6Addr,
interface: u32
) -> Result<(), Error>
Executes an operation of the IPV6_DROP_MEMBERSHIP
type.
For more information about this option, see
join_multicast_v6
.
pub fn take_error(&self) -> Result<Option<Error>, Error>
1.9.0[src]
Gets 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.
Examples
use std::net::UdpSocket; let socket = UdpSocket::bind("127.0.0.1:34254").expect("couldn't bind to address"); match socket.take_error() { Ok(Some(error)) => println!("UdpSocket error: {:?}", error), Ok(None) => println!("No error"), Err(error) => println!("UdpSocket.take_error failed: {:?}", error), }
pub fn connect<A>(&self, addr: A) -> Result<(), Error> where
A: ToSocketAddrs,
1.9.0[src]
A: ToSocketAddrs,
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.
If addr
yields multiple addresses, connect
will be attempted with
each of the addresses until the underlying OS function returns no
error. Note that usually, a successful connect
call does not specify
that there is a remote server listening on the port, rather, such an
error would only be detected after the first send. If the OS returns an
error for each of the specified addresses, the error returned from the
last connection attempt (the last address) is returned.
Examples
Creates a UDP socket bound to 127.0.0.1:3400
and connect the socket to
127.0.0.1:8080
:
use std::net::UdpSocket; let socket = UdpSocket::bind("127.0.0.1:3400").expect("couldn't bind to address"); socket.connect("127.0.0.1:8080").expect("connect function failed");
Unlike in the TCP case, passing an array of addresses to the connect
function of a UDP socket is not a useful thing to do: The OS will be
unable to determine whether something is listening on the remote
address without the application sending data.
pub fn send(&self, buf: &[u8]) -> Result<usize, Error>
1.9.0[src]
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.
Examples
use std::net::UdpSocket; let socket = UdpSocket::bind("127.0.0.1:34254").expect("couldn't bind to address"); socket.connect("127.0.0.1:8080").expect("connect function failed"); socket.send(&[0, 1, 2]).expect("couldn't send message");
pub fn recv(&self, buf: &mut [u8]) -> Result<usize, Error>
1.9.0[src]
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.
The function must be called with valid byte array buf
of sufficient size to
hold the message bytes. If a message is too long to fit in the supplied buffer,
excess bytes may be discarded.
The connect
method will connect this socket to a remote address. This
method will fail if the socket is not connected.
Examples
use std::net::UdpSocket; let socket = UdpSocket::bind("127.0.0.1:34254").expect("couldn't bind to address"); socket.connect("127.0.0.1:8080").expect("connect function failed"); let mut buf = [0; 10]; match socket.recv(&mut buf) { Ok(received) => println!("received {} bytes {:?}", received, &buf[..received]), Err(e) => println!("recv function failed: {:?}", e), }
pub fn peek(&self, buf: &mut [u8]) -> Result<usize, Error>
1.18.0[src]
Receives single datagram on the socket from the remote address to which it is connected, without removing the message from input queue. On success, returns the number of bytes peeked.
The function must be called with valid byte array buf
of sufficient size to
hold the message bytes. If a message is too long to fit in the supplied buffer,
excess bytes may be discarded.
Successive calls return the same data. This is accomplished by passing
MSG_PEEK
as a flag to the underlying recv
system call.
Do not use this function to implement busy waiting, instead use libc::poll
to
synchronize IO events on one or more sockets.
The connect
method will connect this socket to a remote address. This
method will fail if the socket is not connected.
Errors
This method will fail if the socket is not connected. The connect
method
will connect this socket to a remote address.
Examples
use std::net::UdpSocket; let socket = UdpSocket::bind("127.0.0.1:34254").expect("couldn't bind to address"); socket.connect("127.0.0.1:8080").expect("connect function failed"); let mut buf = [0; 10]; match socket.peek(&mut buf) { Ok(received) => println!("received {} bytes", received), Err(e) => println!("peek function failed: {:?}", e), }
pub fn set_nonblocking(&self, nonblocking: bool) -> Result<(), Error>
1.9.0[src]
Moves this UDP socket into or out of nonblocking mode.
This will result in recv
, recv_from
, send
, and send_to
operations becoming nonblocking, i.e., immediately returning from their
calls. If the IO operation is successful, Ok
is returned and no
further action is required. If the IO operation could not be completed
and needs to be retried, an error with kind
io::ErrorKind::WouldBlock
is returned.
On Unix platforms, calling this method corresponds to calling fcntl
FIONBIO
. On Windows calling this method corresponds to calling
ioctlsocket
FIONBIO
.
Examples
Creates a UDP socket bound to 127.0.0.1:7878
and read bytes in
nonblocking mode:
use std::io; use std::net::UdpSocket; let socket = UdpSocket::bind("127.0.0.1:7878").unwrap(); socket.set_nonblocking(true).unwrap(); let mut buf = [0; 10]; let (num_bytes_read, _) = loop { match socket.recv_from(&mut buf) { Ok(n) => break n, Err(ref e) if e.kind() == io::ErrorKind::WouldBlock => { // wait until network socket is ready, typically implemented // via platform-specific APIs such as epoll or IOCP wait_for_fd(); } Err(e) => panic!("encountered IO error: {}", e), } }; println!("bytes: {:?}", &buf[..num_bytes_read]);
