#include <bslmf_usesallocator.h>
This struct template implements a meta-function to determine whether a (template parameter) t_TYPE uses a given (template parameter) t_ALLOCATOR_TYPE. This struct derives from bsl::true_type if t_TYPE uses t_ALLOCATOR_TYPE and from bsl::false_type otherwise. This meta-function has the same syntax as the uses_allocator meta-function defined in the C++11 standard [allocator.uses.trait].
