Defined in header <memory>
template< class T, class Alloc, class... Args > constexpr T make_obj_using_allocator( const Alloc& alloc, Args&&... args );		(since C++20)

Creates an object of the given type T by means of uses-allocator construction.

Equivalent to

return std::make_from_tuple<T>(
    std::uses_allocator_construction_args<T>(alloc, std::forward<Args>(args)...)
);

Parameters

alloc	-	the allocator to use
args	-	the arguments to pass to T's constructor

Return value

The newly-created object of type T.

Exceptions

May throw any exception thrown by the constructor of T, typically including std::bad_alloc.
