    /// A `GSocketService` 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 [`incoming`][struct@crate::SocketService#incoming]
    /// signal is emitted.
    ///
    /// A `GSocketService` 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
    /// `GSocketService`. The first is to create the service using
    /// [`new()`][Self::new()] and to connect to the
    /// [`incoming`][struct@crate::SocketService#incoming] signal. The second is to subclass
    /// `GSocketService` 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 (see
    /// [`glib::MainContext::push_thread_default()`][crate::glib::MainContext::push_thread_default()]) 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.
    ///
    /// ## Properties
    ///
    ///
    /// #### `active`
    ///  Whether the service is currently accepting connections.
    ///
    /// Readable | Writeable | Construct
    /// <details><summary><h4>SocketListener</h4></summary>
    ///
    ///
    /// #### `listen-backlog`
    ///  The number of outstanding connections in the listen queue.
    ///
    /// Readable | Writeable | Construct
    /// </details>
    ///
    /// ## Signals
    ///
    ///
    /// #### `incoming`
    ///  The ::incoming signal is emitted when a new incoming connection
    /// to @service needs to be handled. The handler must initiate the
    /// handling of @connection, but may not block; in essence,
    /// asynchronous operations must be used.
    ///
    /// @connection will be unreffed once the signal handler returns,
    /// so you need to ref it yourself if you are planning to use it.
    ///
    ///
    /// <details><summary><h4>SocketListener</h4></summary>
    ///
    ///
    /// #### `event`
    ///  Emitted when @listener's activity on @socket changes state.
    /// Note that when @listener is used to listen on both IPv4 and
    /// IPv6, a separate set of signals will be emitted for each, and
    /// the order they happen in is undefined.
