NAME

       __gnu_pbds::hash_load_check_resize_trigger< External_Load_Access, Size_Type > - A resize
       trigger policy based on a load check. It keeps the load factor between some load factors
       load_min and load_max.

SYNOPSIS

       Inherits __gnu_pbds::detail::hash_load_check_resize_trigger_size_base< std::size_t, false
       >.

       Inherited by __gnu_pbds::hash_standard_resize_policy< Size_Policy, Trigger_Policy,
       External_Size_Access, Size_Type >.

Detailed Description

   template<bool External_Load_Access = false, typename Size_Type = std::size_t>
       class __gnu_pbds::hash_load_check_resize_trigger< External_Load_Access, Size_Type >" A
       resize trigger policy based on a load check. It keeps the load factor between some load
       factors load_min and load_max.

       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.
