This implementation addresses issue #7 by replacing the
yield-itercrate dependency with the standard library'sstd::iter::from_coroutinefunction. While the current implementation still collects into a Vec first (due to the callback-based architecture), it uses generators to create the iterator, preparing the codebase for future true streaming implementations.The change removes the need for external crate dependencies while using Rust's native generator support, providing better memory efficiency and a more idiomatic approach to iterator creation.
