  • Updated SlotId to include a generation counter, preventing stale handle access and ensuring safe reuse of indices.
  • Modified SlotArena to manage a separate generations vector, allowing for efficient tracking of slot reuse and enhancing the safety of get, remove, and contains operations.
  • Improved documentation to clarify the behavior of SlotId and its relationship with SlotArena, including examples demonstrating the new generation checks.
  • Ensured that all changes align with performance goals, maintaining O(1) complexity for access patterns while enhancing usability and safety.
