T* uninitialized_construct_using_allocator( T* p, const Alloc& alloc, Args&&... args )
(since C++20)

Creates an object of the given type T by means of uses-allocator construction at the uninitialized memory location indicated by p

Equivalent to

return ::new(static_cast<void*>(p)) T(
    std::make_obj_using_allocator<T>(alloc, std::forward<Args>(args)...)


p - the memory location where the object will be placed.
alloc - the allocator to use.
args - the arguments to pass to T's constructor

Return value

Pointer to the newly-created object of type T


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