constexprstd::any::any()[inline],[constexpr],[noexcept]
       Default constructor, creates an empty object.

   std::any::any(constany&__other)[inline]
       Copy constructor, copies the state of __other.

   std::any::any(any&&__other)[inline],[noexcept]
       Move constructor, transfer the state from __other.

       Postcondition
           !__other.has_value() (this postcondition is a GNU extension)

       Construct with a copy of __value as the contained object.

   template<typename_Tp,typename..._Args,typename_VTp=decay_t<_Tp>,typename_Mgr=_Manager<_VTp>,__any_constructible_t<_VTp,_Args&&...>=false>std::any::any(in_place_type_t<_Tp>,_Args&&...__args)[inline],[explicit]
       Construct with an object created from __args as the contained object.

       Construct with an object created from __il and __args as the contained object.

   std::any::~any()[inline]
       Destructor, calls reset()

       A type-safe container of any type.

       An any object's state is either empty or it stores a contained object of CopyConstructible type.

       Since
           C++17

template<typename_Tp,typename..._Args>__emplace_t<decay_t<_Tp>,_Args...>std::any::emplace(_Args&&...__args)[inline]
       Emplace with an object created from __args as the contained object.

   template<typename_Tp,typename_Up,typename..._Args>__emplace_t<decay_t<_Tp>,initializer_list<_Up>&,_Args&&...>std::any::emplace(initializer_list<_Up>__il,_Args&&...__args)[inline]
       Emplace with an object created from __il and __args as the contained object.

   boolstd::any::has_value()const[inline],[noexcept]
       Reports whether there is a contained object or not.

   template<typename_Tp>enable_if_t<is_copy_constructible<_Decay_if_not_any<_Tp>>::value,any&>std::any::operator=(_Tp&&__rhs)[inline]
       Store a copy of __rhs as the contained object.

   any&std::any::operator=(any&&__rhs)[inline],[noexcept]
       Move assignment operator.

       Postcondition
           !__rhs.has_value() (not guaranteed for other implementations)

   any&std::any::operator=(constany&__rhs)[inline]
       Copy the state of another object.

   voidstd::any::reset()[inline],[noexcept]
       If not empty, destroy the contained object.

   voidstd::any::swap(any&__rhs)[inline],[noexcept]
       Exchange state with another object.

   consttype_info&std::any::type()const[inline],[noexcept]
       The typeid of the contained object, or typeid(void) if empty.
