Implementations

impl LocalUdpSocket

fn with_sock_ref<F, R>(&self, f: F) -> R

where for<'a> F: FnOnce(SockRef<'a>) -> R,

impl LocalUdpSocket

fn split_borrow( &mut self, ) -> (&mut HandlerGuardState, &Arc<Selector>, &mut UdpSocket)

Trait Implementations

impl Debug for LocalUdpSocket

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

Formats the value using the given formatter.

impl VirtualConnectionlessSocket for LocalUdpSocket

fn try_send_to(&mut self, data: &[u8], addr: SocketAddr) -> Result<usize>

Sends out a datagram or stream of bytes on this socket to a specific address

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

Recv a packet from the socket

impl VirtualIoSource for LocalUdpSocket

fn remove_handler(&mut self)

Removes a previously registered waker using a token

fn poll_read_ready(&mut self, cx: &mut Context<'_>) -> Poll<Result<usize>>

Polls the source to see if there is data waiting

fn poll_write_ready(&mut self, cx: &mut Context<'_>) -> Poll<Result<usize>>

Polls the source to see if data can be sent

impl VirtualSocket for LocalUdpSocket

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

Sets how many network hops the packets are permitted for new connections

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

Returns the maximum number of network hops before packets are dropped

fn addr_local(&self) -> Result<SocketAddr>

Returns the local address for this socket

fn status(&self) -> Result<SocketStatus>

Returns the status/state of the socket

fn set_handler( &mut self, handler: Box<dyn InterestHandler + Send + Sync>, ) -> Result<()>

Registers a waker for when this connection is ready to receive more data. Uses a stack machine which means more than one waker can be registered

impl VirtualUdpSocket for LocalUdpSocket

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

Sets a flag that means that the UDP socket is able to receive and process broadcast packets.

fn broadcast(&self) -> Result<bool>

Indicates if the SO_BROADCAST flag is set which means that the UDP socket will receive and process broadcast packets

fn set_multicast_loop_v4(&mut self, val: bool) -> Result<()>

Sets a flag that indicates if multicast packets that this socket is a member of will be looped back to the sending socket. This applies to IPv4 addresses

fn multicast_loop_v4(&self) -> Result<bool>

Gets a flag that indicates if multicast packets that this socket is a member of will be looped back to the sending socket. This applies to IPv4 addresses

fn set_multicast_loop_v6(&mut self, val: bool) -> Result<()>

Sets a flag that indicates if multicast packets that this socket is a member of will be looped back to the sending socket. This applies to IPv6 addresses

fn multicast_loop_v6(&self) -> Result<bool>

Gets a flag that indicates if multicast packets that this socket is a member of will be looped back to the sending socket. This applies to IPv6 addresses

fn set_multicast_ttl_v4(&mut self, ttl: u32) -> Result<()>

Sets the TTL for IPv4 multicast packets which is the number of network hops before the packet is dropped

fn multicast_ttl_v4(&self) -> Result<u32>

Gets the TTL for IPv4 multicast packets which is the number of network hops before the packet is dropped

fn join_multicast_v4( &mut self, multiaddr: Ipv4Addr, iface: Ipv4Addr, ) -> Result<()>

Tells this interface that it will subscribe to a particular multicast address. This applies to IPv4 addresses

fn leave_multicast_v4( &mut self, multiaddr: Ipv4Addr, iface: Ipv4Addr, ) -> Result<()>

Tells this interface that it will unsubscribe to a particular multicast address. This applies to IPv4 addresses

fn join_multicast_v6(&mut self, multiaddr: Ipv6Addr, iface: u32) -> Result<()>

Tells this interface that it will subscribe to a particular multicast address. This applies to IPv6 addresses

fn leave_multicast_v6(&mut self, multiaddr: Ipv6Addr, iface: u32) -> Result<()>

Tells this interface that it will unsubscribe to a particular multicast address. This applies to IPv6 addresses

fn addr_peer(&self) -> Result<Option<SocketAddr>>

Returns the remote address of this UDP socket if it has been connected to a specific target destination address
