Worked on the apache/arrow-rs repository to enhance the RowFilter API by exposing its internal predicates through new public accessor methods. This change, implemented in Rust with a focus on API design, allows users to inspect and consume filter predicates directly, improving both usability and integration with downstream systems. The approach emphasized code readability and module ergonomics, aligning with broader goals of openness and component reusability. By enabling easier debugging and more advanced query composition, the update supports faster issue diagnosis and more robust integration workflows for users building on top of the library. No major bugs were addressed during this period.
