Trait Implementations

impl Debug for LocalUdpSocket

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

Formats the value using the given formatter.

impl VirtualConnectionlessSocket for LocalUdpSocket

fn poll_send_to( &mut self, cx: &mut Context<'_>, data: &[u8], addr: SocketAddr ) -> Poll<Result<usize, NetworkError>>

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

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

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

fn poll_recv_from( &mut self, cx: &mut Context<'_>, buf: &mut [MaybeUninit<u8>] ) -> Poll<Result<(usize, SocketAddr), NetworkError>>

Recv a packet from the socket

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

Recv a packet from the socket

impl VirtualSocket for LocalUdpSocket

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

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

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

Returns the maximum number of network hops before packets are dropped

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

Returns the local address for this socket

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

Returns the status/state of the socket

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

Polls the socket for when there is data to be received

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

Polls the socket for when the backpressure allows for writing to the socket

impl VirtualUdpSocket for LocalUdpSocket

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

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

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

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<(), NetworkError>

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, NetworkError>

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<(), NetworkError>

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, NetworkError>

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<(), NetworkError>

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, NetworkError>

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<(), NetworkError>

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<(), NetworkError>

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<(), NetworkError>

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<(), NetworkError>

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

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

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