GetDefaultWebsocketTransport returns no NewServer parameter type necessary

[odhs]

In server examples to use we have:

server := gosocketio.NewServer(transport.GetDefaultWebsocketTransport())

But transport.GetDefaultWebsocketTransport() in package transport doesn't match with

func NewServer(tr transport.Transport) *Server in file server.go

Excerpt of the file wesocket.go in package transport:

/**
Returns websocket connection with default params
*/
func GetDefaultWebsocketTransport() *WebsocketTransport {
	return &WebsocketTransport{
		PingInterval:   WsDefaultPingInterval,
		PingTimeout:    WsDefaultPingTimeout,
		ReceiveTimeout: WsDefaultReceiveTimeout,
		SendTimeout:    WsDefaultSendTimeout,
		BufferSize:     WsDefaultBufferSize,
	}
}

Excerpt of the file transport.go in package transport:

/**
Connection factory for given transport
*/
type Transport interface {
	/**
	Get client connection
	*/
	Connect(url string) (conn Connection, err error)

	/**
	Handle one server connection
	*/
	HandleConnection(w http.ResponseWriter, r *http.Request) (conn Connection, err error)

	/**
	Serve HTTP request after making connection and events setup
	*/
	Serve(w http.ResponseWriter, r *http.Request)
}

Excerpt of the file server.go in package gosocketio, look the parameter is tr transport.Transport

/**
Create new socket.io server
*/
func NewServer(tr transport.Transport) *Server {
	s := Server{}
	s.initMethods()
	s.tr = tr
	s.channels = make(map[string]map[*Channel]struct{})
	s.rooms = make(map[*Channel]map[string]struct{})
	s.sids = make(map[string]*Channel)
	s.onConnection = onConnectStore
	s.onDisconnection = onDisconnectCleanup

	return &s
}

Excerpt of the file server.go in package main directory examples, look, the parameter doesn't match with func NewServer

func main() {
	server := gosocketio.NewServer(transport.GetDefaultWebsocketTransport())

	server.On(gosocketio.OnConnection, func(c *gosocketio.Channel) {
		log.Println("Connected")

		c.Emit("/message", Message{10, "main", "using emit"})

		c.Join("test")
		c.BroadcastTo("test", "/message", Message{10, "main", "using broadcast"})
	})
	server.On(gosocketio.OnDisconnection, func(c *gosocketio.Channel) {
		log.Println("Disconnected")
	})

	server.On("/join", func(c *gosocketio.Channel, channel Channel) string {
		time.Sleep(2 * time.Second)
		log.Println("Client joined to ", channel.Channel)
		return "joined to " + channel.Channel
	})

	serveMux := http.NewServeMux()
	serveMux.Handle("/socket.io/", server)

	log.Println("Starting server...")
	log.Panic(http.ListenAndServe(":3811", serveMux))
}

Thank you for attention
