Struct PathUnawareUdpScionSocket 

pub struct PathUnawareUdpScionSocket { /* private fields */ }

A path unaware UDP SCION socket.

Implementations

impl PathUnawareUdpScionSocket

pub fn send_to_via<'a>( &'a self, payload: &[u8], destination: SocketAddr, path: &Path<&[u8]>, ) -> BoxFuture<'a, Result<(), ScionSocketSendError>>

Send a SCION UDP datagram via the given path.

Cancel safety

This method is cancel-safe. If the future is dropped before completion, the packet may be silently lost, but no socket state is corrupted and the socket remains usable.

pub fn recv_from_with_path<'a>( &'a self, buffer: &'a mut [u8], path_buffer: &'a mut [u8], ) -> BoxFuture<'a, Result<(usize, SocketAddr, Path<&'a mut [u8]>), ScionSocketReceiveError>>

Receive a SCION packet with the sender and path.

Cancel safety

This method is cancel-safe. The only await point is the inner underlay receive. If the future is dropped while waiting for a packet, no packet data is consumed and buffer and path_buffer are left unmodified. If a packet has already been received (i.e., the future is dropped after data has been written into the buffers), this cannot occur in practice because those steps run synchronously within a single poll invocation.

pub fn recv_from<'a>( &'a self, buffer: &'a mut [u8], ) -> BoxFuture<'a, Result<(usize, SocketAddr), ScionSocketReceiveError>>

Receive a SCION packet with the sender.

Cancel safety

This method is cancel-safe. If the future is dropped while waiting for a packet, no packet is consumed and buffer is left unmodified. The contents of buffer are only valid after the method returns Ok.
