�st�dS)adA coroutine which creates a TCP server bound to host and port.

        The return value is a Server object which can be used to stop
        the service.

        If host is an empty string or None all interfaces are assumed
        and a list of multiple sockets will be returned (most likely
        one for IPv4 and another one for IPv6). The host parameter can also be
        a sequence (e.g. list) of hosts to bind to.

        family can be set to either AF_INET or AF_INET6 to force the
        socket to use IPv4 or IPv6. If not set it will be determined
        from host (defaults to AF_UNSPEC).

        flags is a bitmask for getaddrinfo().

        sock can optionally be specified in order to use a preexisting
        socket object.

        backlog is the maximum number of queued connections passed to
        listen() (defaults to 100).

        ssl can be set to an SSLContext to enable SSL over the
        accepted connections.

        reuse_address tells the kernel to reuse a local socket in
        TIME_WAIT state, without waiting for its natural timeout to
        expire. If not specified will automatically be set to True on
        UNIX.

        reuse_port tells the kernel to allow this endpoint to be bound to
        the same port as other existing endpoints are bound to, so long as
        they all set this flag when being created. This option is not
        supported on Windows.

        ssl_handshake_timeout is the time in seconds that an SSL server
        will wait for completion of the SSL handshake before aborting the
        connection. Default is 60s.

        start_serving set to True (default) causes the created server
        to start accepting connections immediately.  When set to False,
        the user should await Server.start_serving() or Server.serve_forever()
        to make the server to start accepting connections.

        server socket to.

        sock can optionally be specified in order to use a preexisting

        This method will try to establish the endpoint in the background.
        When successful, the coroutine returns a (transport, protocol) pair.

        protocol_factory must be a callable returning a protocol instance.

        socket family AF_INET, socket.AF_INET6 or socket.AF_UNIX depending on
        host (or family if specified), socket type SOCK_DGRAM.

        reuse_address tells the kernel to reuse a local socket in
        TIME_WAIT state, without waiting for its natural timeout to

        supported on Windows and some UNIX's. If the
        :py:data:`~socket.SO_REUSEPORT` constant is not defined then this
        capability is unsupported.

        allow_broadcast tells the kernel to allow this endpoint to send
