template<typename_Tp,typename_Dp=default_delete<_Tp>>template<typename_Del=_Dp,typename=_DeleterConstraint<_Del>>constexprstd::unique_ptr<_Tp,_Dp>::unique_ptr()[inline],[constexpr],[noexcept]
       Default constructor, creates a unique_ptr that owns nothing.

   template<typename_Tp,typename_Dp=default_delete<_Tp>>template<typename_Del=_Dp,typename=_DeleterConstraint<_Del>>constexprstd::unique_ptr<_Tp,_Dp>::unique_ptr(pointer__p)[inline],[explicit],[constexpr],[noexcept]
       Takes ownership of a pointer.

       Parameters__p A pointer to an object of element_type

       The deleter will be value-initialized.

       Takes ownership of a pointer.

       Parameters__p A pointer to an object of element_type
           __d A reference to a deleter.

       The deleter will be initialized with __d

       Takes ownership of a pointer.

       Parameters__p A pointer to an object of element_type
           __d An rvalue reference to a (non-reference) deleter.

       The deleter will be initialized with std::move(__d)

   template<typename_Tp,typename_Dp=default_delete<_Tp>>template<typename_Del=_Dp,typename=_DeleterConstraint<_Del>>constexprstd::unique_ptr<_Tp,_Dp>::unique_ptr(nullptr_t)[inline],[constexpr],[noexcept]
       Creates a unique_ptr that owns nothing.

   template<typename_Tp,typename_Dp=default_delete<_Tp>>std::unique_ptr<_Tp,_Dp>::unique_ptr(unique_ptr<_Tp,_Dp>&&)[default]
       Move constructor.

       Converting constructor from another type. Requires that the pointer owned by __u is convertible to the
       type of pointer owned by this object, __u does not own an array, and __u has a compatible deleter type.

   template<typename_Tp,typename_Dp>template<typename_Up,typename>std::unique_ptr<_Tp,_Dp>::unique_ptr(auto_ptr<_Up>&&__u)[inline],[noexcept]
       Converting constructor from auto_ptr.

   template<typename_Tp,typename_Dp=default_delete<_Tp>>std::unique_ptr<_Tp,_Dp>::~unique_ptr()[inline],[noexcept]
       Destructor, invokes the deleter if the stored pointer is not null.
