23.10.8.2 Allocator traits static member functions [allocator.traits.members]

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()/sizeof(value_type).

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.
