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

NAME
     std::bit_not - std::bit_not

Synopsis
	Defined in header <functional>
	template< class T = void >	(since C++14)
	struct bit_not;

	Function  object for performing bitwise NOT. Effectively calls operator~
     on type T.

Specializations
	The standard library provides a specialization of std::bit_not when T is
     not
	specified, which leaves the parameter types and return type  to  be  de-
     duced.

	bit_not<void> function object implementing ~x deducing parameter and re-
     turn types
	(C++14)       (class template specialization)

Member types
	Type						      Definition
	result_type (deprecated in C++17)(removed in C++20)   T
	argument_type (deprecated in C++17)(removed in C++20) T

Member functions
	operator() returns the result of bitwise NOT of its argument
	(C++14)    (public member function)

     std::bit_not::operator()

	constexpr T operator()( const T& arg ) const;  (since C++14)

	Returns the result of bitwise NOT of arg.

Parameters
	arg - value to compute bitwise NOT of

Return value
	The result of ~arg.

Exceptions
	May throw implementation-defined exceptions.

Possible implementation
	constexpr T operator()(const T& arg) const
	{
	    return ~arg;
	}

Notes
	Although  std::bit_not	is  added  via	post-C++11 proposal N3421, it is
     treated as a
	part of the resolution for LWG issue 660  (except  for	its  transparent
     specialization
	std::bit_not<>)  by  common implementations, and thus available in their
     C++98/03
	mode.
