aligned_storage is deprecated by C++23

template <typename ValueType, bool StoreHash> class bucket_entry : public bucket_entry_hash<StoreHash> { using bucket_hash = bucket_entry_hash<StoreHash>;

visual studio 2022 v17.3.0 preview reported this as error.

may change to

private: distance_type m_dist_from_ideal_bucket; bool m_last_bucket; alignas(value_type) std::byte m_value[sizeof(value_type)];
