C++26 introduces std::hive, a new container offering stable pointers and iterators during insertions and erasures while maintaining good cache locality through contiguous memory blocks. Derived from plf::colony after eight years and 28 revisions, it uses multiple memory blocks, a skipfield for efficient iteration past erased elements, and slot reuse to combine the benefits of vector-like performance with list-like stability.
Background
C++26 continues the trend of expanding the standard library with new containers, following recent additions like std::inplace_vector. The plf::colony library has long been a popular third-party solution for scenarios requiring stable references in dynamic collections.
