I already have a use case for this and I am thinking about replacing my component for this by your library.

I am a developer of PortPHP. I've created a pagerfanta adapter which let's you iterate through a large set of elements using deferred loading (for example from database) and let's you to write it to any destinations.

While my adapter is created specifically for Port, I like your implementation because it exposes data through a generic iterator. Since we also have an iterator implementation for data sources, I am thinking about to drop the pagerfanta implementation and simply use this package with an iterator reader.
