//! Generic, datagram-based CoAP backend, with associated socket abstractions.
//!
//! The actual backend is [`DatagramLocalEndpoint`]. It uses an asynchronous datagram
//! socket that implements the trait [`AsyncDatagramSocket`] and all of its required dependency
//! traits ([`DatagramSocketTypes`], [`AsyncSendTo`], [`AsyncRecvFrom`], [`MulticastSocket`],
//! [`Send`], and [`Sync`]).

//! [`AsyncRecvFrom`]: datagram::AsyncRecvFrom
