template<class T> constexpr void destroy_at(T* location);namespace ranges { template<[destructible](concept.destructible#concept:destructible "18.4.10 Concept destructible [concept.destructible]") T> constexpr void destroy_at(T* location) noexcept;}

Effects:

• If T is an array type, equivalent todestroy(begin(*location), end(*location)).
• Otherwise, equivalent tolocation->~T().

template<class NoThrowForwardIterator> constexpr void destroy(NoThrowForwardIterator first, NoThrowForwardIterator last);

Effects: Equivalent to:for (; first != last; ++first) destroy_at(addressof(*first));

Effects: Equivalent to:for (; first != last; ++first) destroy_at(addressof(*first));return first;

template<class NoThrowForwardIterator, class Size> constexpr NoThrowForwardIterator destroy_n(NoThrowForwardIterator first, Size n);

Effects: Equivalent to:for (; n > 0; (void)++first, --n) destroy_at(addressof(*first));return first;

Effects: Equivalent to:return destroy(counted_iterator(std::move(first), n), default_sentinel).base();
