Thanks for your contribution! I left my first comments. I will make a second pass once these comments are addressed.

[Conaclos]

Once the comments are addressed I think we can merge your contribution :)

We could avoid allocating a Vec by using std::iter::successors.
We could clone the iterator at call site if we need to iterate over it several times.

This is a refactor that we can delay to a future PR.

[GunseiKPaseri]

Sorry. I didn't know the appropriate way to use successors while simultaneously obtaining the final expression.

@GunseiKPaseri Looks good to me. Could you merge main in your PR and solve conflicts? This will allow us to merge your PR :)
