C++26: std::hive
Summary
C++26 introduces std::hive, a multi-block container with a skipfield for O(1) iteration past erased elements and erased-slot reuse. It provides stable pointers and iterators, with insertion that is unspecified and no random access. The article contrasts std::hive with std::vector and std::list, covers block capacity tuning and hive-specific operations, and highlights its suitability for game engines and systems programming where frequent insertions and cross-references occur.
