std::is_implicit_lifetime(3)   C++ Standard Libary  std::is_implicit_lifetime(3)

NAME
     std::is_implicit_lifetime - std::is_implicit_lifetime

Synopsis
	Defined in header <type_traits>
	template< class T >		 (since C++23)
	struct is_implicit_lifetime;

	std::is_implicit_lifetime is a UnaryTypeTrait.

	If  T  is  an implicit-lifetime type, provides the member constant value
     equal to true.
	For any other type, value is false.

	The behavior is undefined if T is an incomplete type other than an array
     type or
	(possibly cv-qualified) void.

	If the program adds specializations for std::is_implicit_lifetime or
	std::is_implicit_lifetime_v, the behavior is undefined.

Template parameters
	T - a type to check

	Helper variable template

	template< class T >
	inline	     constexpr	     bool	 is_implicit_lifetime_v        =
     (since C++23)
	is_implicit_lifetime<T>::value;

     Inherited from std::integral_constant

Member constants
	value	 true if T is an implicit-lifetime type, false otherwise
	[static] (public static member constant)

Member functions
	operator bool converts the object to bool, returns value
		      (public member function)
	operator()    returns value
	(C++14)       (public member function)

Member types
	Type	   Definition
	value_type bool
	type	   std::integral_constant<bool, value>
