Pull Request Overview
This PR adds a range parameter to the extract_if method to match the standard library's Vec::extract_if implementation. This is a breaking change that allows users to specify which range of elements should be considered for extraction.
Key changes:
- Added a
range: impl RangeBounds<usize>parameter toextract_ifmethod - Introduced a new
resolve_rangehelper function to normalize range bounds into concrete start/end indices - Updated the
Retainstruct to support ranged operations with astop_lenfield - Added comprehensive test coverage for ranged extraction scenarios
