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.

Member Enumeration Documentation

template<bool External_Load_Access = false, typename Size_Type = std::size_t>

anonymous enum

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.
