Defined in header`<stack>`
template<class T,class Container,class Alloc> struct uses_allocator<std::stack<T, Container>, Alloc> :std::uses_allocator<Container, Alloc>::type{};		(since C++11)

Provides a transparent specialization of thestd::uses_allocator type trait forstd::stack: the container adaptor uses allocator if and only if the underlying container does.
