template< class Alloc > struct allocator_traits;		(начиная с C++11)

Шаблон allocator_traits класс предоставляет стандартный способ доступа к различным свойствам распределителей. Стандартные контейнеры и другие стандартные распределители библиотеки компонентов доступа через этот шаблон, который позволяет использовать любой тип класса, как распределитель, пока предоставленные пользователем специализации allocator_traits реализует все необходимые функции.

Original:

The allocator_traits class template provides the standardized way to access various properties of allocators. The standard containers and other standard library components access allocators through this template, which makes it possible to use any class type as an allocator, as long as the user-provided specialization of allocator_traits implements all required functionality.
