/// A [`SocketService`][crate::SocketService] is an object that represents a service that
/// is provided to the network or over local sockets. When a new
/// connection is made to the service the `signal::SocketService::incoming`
/// signal is emitted.
///
/// A [`SocketService`][crate::SocketService] is a subclass of [`SocketListener`][crate::SocketListener] and you need
/// to add the addresses you want to accept connections on with the
/// [`SocketListener`][crate::SocketListener] APIs.
///
/// There are two options for implementing a network service based on
/// [`SocketService`][crate::SocketService]. The first is to create the service using
/// [`new()`][Self::new()] and to connect to the `signal::SocketService::incoming`
/// signal. The second is to subclass [`SocketService`][crate::SocketService] and override the
/// default signal handler implementation.
///
/// In either case, the handler must immediately return, or else it
/// will block additional incoming connections from being serviced.
/// If you are interested in writing connection handlers that contain
/// blocking code then see [`ThreadedSocketService`][crate::ThreadedSocketService].
///
/// The socket service runs on the main loop of the
/// [thread-default context][g-main-context-push-thread-default-context]
/// of the thread it is created in, and is not
/// threadsafe in general. However, the calls to start and stop the
/// service are thread-safe so these can be used from threads that
/// handle incoming clients.
