Struct tokio_uds::RecvDgram
[−]
[src]
pub struct RecvDgram<T> { /* fields omitted */ }
A future for receiving datagrams from a Unix datagram socket.
An example that uses UDP sockets but is still applicable can be found at https://gist.github.com/dermesser/e331094c2ab28fc7f6ba8a16183fe4d5.
Trait Implementations
impl<T> Future for RecvDgram<T> where T: AsMut<[u8]>
[src]
type Item = (UnixDatagram, T, usize, String)
RecvDgram yields a tuple of the underlying socket, the receive buffer, how many bytes were received, and the address (path) of the peer sending the datagram. If the buffer is too small, the datagram is truncated.
type Error = Error
This future yields io::Error if an error occurred.
