var ErrNilServerConfig = fmt.Errorf("Nil server config")

ErrNilServerConfig is returned when a ConnMaster has no server config.

var Upgrader = websocket.Upgrader{
	CheckOrigin: func(r *http.Request) bool { return true },
}

Upgrader is a struct that contains ws protocol upgrade configuration.

Types

type ConnMaster

type ConnMaster struct {
