@dogancanbakir I just tried it, and it only returns the results after the whole enumeration has already been done. The ResultCallback is called here:

And before the Callback is called, it waits for all the results to come in because of this:

So, this is what you were expecting, right?

No, I would expect the result to come in as soon as it is discovered.

Example: Hitting the chaos API takes 10 seconds and yields sub1.target.com and sub2.target.com, whereas hitting securitytrails takes 2 seconds and yields sub3.target.com and sub4.target.com.

I would expect my ResultCallback function to be called 4 times. Twice at 2 seconds (when securitytrails returns results) and twice at 10 seconds (when choas returns results).

The example here also suggests something similar:

But the current behaviour is ResultCallback being called 4 times after the whole scan is completed (in my example, all at 10 seconds).

@dogancanbakir I've submitted a PR for this based on my cursory analysis of the code. Please check it out: #1652
