Iterator method that remembers it's content's positions from the original data structure

1

Critique is welcome!

I have an iterator of elements from a vector, But I need to remember the elements position from the original vector. I don't want to store the element's original position in a tuple with the element, Because that could bloat the iterators size.

I checked out the Standard Library Iterator Page, But I couldn't find what I needed.

Is this by chance what you are looking for?

enumerate()

I tested it in the playground, But it doesn't seem work properly :frowning:

Obviously, you need to enumerate before you filter.

enumerate first, then filter.
