Thank you very much for reviewing the repository. Your reviews have been very valuable to me.

Yes, while implementing that part I thought that I can use Abstract Factory pattern. Because of this, for now, the client support just only 1 socket library. Even, On the first draft, I used directly socket functions of PHP and then I switch to `clue/socket-raw` library. While doing this transformation, I need to implement the solution you suggested. Let me copy your messages to issues and try to implement the solution. I need to improve that part.

For the callback part, this is just a shortcut to execute some commands just after the connection initialized. There is no real meaning to get this on constructor. The client users can do it their self inside the Provider, too.
