Description

As originally posted on Gitter by @microgravitas:

Hi y'all! Can anyone point me to an example of how to implement an Python iterator which does not copy the whole underlying datastructure? All examples I could find used .clone(), something I'd like to avoid---if possible.

I've actually noticed this too about our iterator examples - it would be nice if we could find a way to make the .clone() unnecessary!

Research direction

Start by locating the iterator examples that use .clone() and read the surrounding PyO3 documentation. Determine whether the current Rust/Python API supports an example without copying the underlying data structure; done means the relevant examples show a supported non-cloning approach or clearly document why it is not possible.
