std::alloca...ts::destroy(3) C++ Standard Libary std::alloca...ts::destroy(3) NAME std::allocator_traits::destroy - std::allocator_traits::destroy Synopsis Defined in header <memory> template< class T > (since C++11) static void destroy( Alloc& a, T* p ); (until C++20) template< class T > (since C++20) static constexpr void destroy( Alloc& a, T* p ); Calls the destructor of the object pointed to by p. If possible, does so by calling a.destroy(p). If not possible (e.g. Alloc does not have the member func- tion destroy()), then calls the destructor of *p directly, as p->~T() (until C++20) std::destroy_at(p) (since C++20). Parameters a - allocator to use for destruction p - pointer to the object being destroyed Return value (none) Notes Because this function provides the automatic fall back to direct call to the destructor, the member function destroy() is an optional Allocator re- quirement since C++11.
