Defined in header <tuple>
template< class... Types, class Alloc > struct uses_allocator< std::tuple<Types...>, Alloc > : std::true_type { };		（C++11 起）

這種專業化的std::uses_allocator通知其他庫組件的元組支持的「使用分配器建設的」，即使他們沒有一個嵌套的allocator_type.

Original:

This specialization of std::uses_allocator informs other library components that tuples support uses-allocator construction, even though they do not have a nested allocator_type.

為例

// myalloc is a stateful Allocator with a single-argument constructor
// that takes an int. It has no default constructor.
 
    typedef std::vector<int, myalloc<int>> innervector_t;
    typedef std::tuple<int, innervector_t> elem_t;
    typedef std::scoped_allocator_adaptor< myalloc<elem_t>, myalloc<int>> Alloc;
    Alloc a(1,2);
    std::vector<elem_t, Alloc> v(a);
    v.resize(1);                  // uses allocator #1 for elements of v
    std::get<1>(v[0]).resize(10); // uses allocator #2 for innervector_t
