badeend opened PR #7243 from badeend:udp-streams to bytecodealliance:main:

Introduce new inbound-datagram-stream and outbound-datagram-stream types and moved receive and send methods to those respectively. These streams are returned by bind and can be individually subscribed to. This resolves a design issue where a UDP server would end up in a spin loop because receive returned EWOULDBLOCK but poll_* always returned immediately because the socket was ready for sending. In this new setup, users can poll each direction separately. Fixes https://github.com/WebAssembly/wasi-sockets/issues/64

Additionally

Enable send-like behaviour by making outbound-datagram::remote-address optional. Fixes https://github.com/WebAssembly/wasi-sockets/pull/57

Dropped the network parameter from the connect call, because bind is now _required_ to perform IO.
