Should this be using thrust::distance instead of std::distance? I'm not sure if std::distance works on all iterator types. (I could be wrong here.)

That's a good question. I think it's worth making the change since I can see some code paths that call through to this with thrust iterators. I'm guessing everything works fine or we'd be seeing bugs, but best to be safe nonetheless.

I'll do this in a separate PR though.
