Member Enumeration Documentation

  template<bool External_Load_Access = false, typename Size_Type = std::size_t> anonymous enum [inherited]

Enumerator

external_load_access
    Specifies whether the load factor can be accessed externally. The two options have different trade-offs in terms of flexibility, genericity, and encapsulation.
