public static member function
<memory>
template <class T> static void destroy (allocator_type& alloc, T* p);
Destroy object
Destroys the element object pointed by p without deallocating its storage.
In the non-specialized definition of allocator_traits, this member function callsalloc.destroy(p)if such a call is well formed. Otherwise, it invokesp->~T(). A specialization for a specific allocator type may provide a different definition.
