std::scoped_allocator_adaptor<OuterAlloc,InnerAlloc...>::allocate

Defined in header `<scoped_allocator>`
	(1)
pointer allocate( size_type n );		(since C++11) (until C++20)
[[nodiscard]] pointer allocate( size_type n );		(since C++20)
	(2)
pointer allocate( size_type n, const_void_pointer hint );		(since C++11) (until C++20)
[[nodiscard]] pointer allocate( size_type n, const_void_pointer hint );		(since C++20)

Uses the outer allocator to allocate uninitialized storage.

1) Calls std::allocator_traits<OuterAlloc>::allocate(outer_allocator(), n)

2) Additionally provides memory locality hint, by calling std::allocator_traits<OuterAlloc>::allocate(outer_allocator(), n, hint)

n	-	the number of objects to allocate storage for
hint	-	pointer to a nearby memory location

The pointer to the allocated storage.

allocate	allocates uninitialized storage (public member function of `std::allocator<T>`)
allocate [static]	allocates uninitialized storage using the allocator (public static member function of `std::allocator_traits<Alloc>`)
