static pointer allocate(Alloc& a, size_type n);
Returns: a.allocate(n).
static pointer allocate(Alloc& a, size_type n, const_void_pointer hint);
Returns: a.allocate(n, hint) if that expression is well-formed; otherwise, a.allocate(n).
static void deallocate(Alloc& a, pointer p, size_type n);
Effects: calls a.deallocate(p, n).
Throws: Nothing.
template <class T, class... Args>
static void construct(Alloc& a, T* p, Args&&... args);
Effects: calls a.construct(p, std::forward<Args>(args)...) if that call is well-formed; otherwise, invokes ::new (static_cast<void*>(p)) T(std::forward<Args>(args)...).
template <class T>
static void destroy(Alloc& a, T* p);
Effects: calls a.destroy(p) if that call is well-formed; otherwise, invokes p->~T().
static size_type max_size(const Alloc& a) noexcept;
Returns: a.max_size() if that expression is well-formed; otherwise, numeric_limits<size_type>::max().
static Alloc select_on_container_copy_construction(const Alloc& rhs);
Returns: rhs.select_on_container_copy_construction() if that expression is well-formed; otherwise, rhs.
