Allow serializing the iterators #13

Closed kewisch closed 9 years ago

kewisch commented 9 years ago

I'd like to save the state of the iterator to a file, so that I can continue iterating at that exact point on next run. A few values are held via closure, so I can't just serialize the iterator itself. Any ideas?

You can save the seed array and its index then use .nth(index) to resume.

Thanks, setting cp.index to the previous value seems to do it for the cartesian product!
