Expand description

Reads datagrams from a socket.

Implemented as an extension trait, adding utility methods to all DatagramSocketRecv types. Callers will tend to import this trait instead of DatagramSocketRecv.

Provided Methods§

Source

fn recv(&mut self, buf: &mut [u8]) -> impl Future<Output = Result<usize>> + Send

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.

Source

fn recv_from( &mut self, buf: &mut [u8], ) -> impl Future<Output = Result<(usize, SocketAddr)>> + Send

Receives a single datagram message on the socket. On success, returns the number of bytes read and the origin.

Source

fn recv_many( &mut self, bufs: &mut [ReadBuf<'_>], ) -> impl Future<Output = Result<usize>> + Send

Receives multiple datagrams on the socket from the remote address to which it is connected. Returns the number of buffers used (i.e. number of datagrams read). Each used buffer can be read up to its filled().len().

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
