C++26: std::hive
TL;DR
C++26 introduces std::hive, a new container designed for game engines managing numerous entities. It offers stable pointers and efficient memory management, addressing issues with traditional containers like std::vector and std::list.
✦ Why It Matters
Consider integrating std::hive into your game engine for better entity management today.
Key Takeaways
- Utilize std::hive for stable pointers in entity management.
- Leverage O(1) amortized insertions and erasures for performance.
- Take advantage of skipfield for efficient iteration.
- Control block sizes to optimize memory usage.
How It Works
std::hive operates using multiple independently allocated memory blocks, which prevents reallocation during insertions. It employs a skipfield that tracks erased slots, allowing iterators to jump over these slots efficiently, thus maintaining O(1) amortized iteration.
This clever design ensures that pointers and iterators remain valid even after multiple insertions and deletions.
