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

NAME
     std::bit_or - std::bit_or

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

	Function  object  for performing bitwise OR. Effectively calls operator|
     on type T.

Specializations
	The standard library provides a specialization of std::bit_or when T
	is not specified, which leaves the parameter types and return type to
	be deduced.
									       (since
     C++14)
	bit_or<void> function object implementing x | y deducing parameter and
	(C++14)      return types
		     (class template specialization)

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

	These	member	 types	 are   obtained    via	  publicly    inheriting
     (until C++11)
	std::binary_function<T, T, T>.

Member functions
	operator() returns the result of bitwise OR of two arguments
		   (public member function)

     std::bit_or::operator()

	T  operator()(	const  T&  lhs,  const T& rhs ) const;		  (until
     C++14)
	constexpr T operator()( const T& lhs, const  T&  rhs  )  const;   (since
     C++14)

	Returns the result of bitwise OR of lhs and rhs.

Parameters
	lhs, rhs - values to compute bitwise OR of

Return value
	The result of lhs | rhs.

Exceptions
	May throw implementation-defined exceptions.

Possible implementation
	constexpr T operator()(const T& lhs, const T& rhs) const
	{
	    return lhs | rhs;
	}

	Defect reports

	The  following	behavior-changing  defect  reports were applied retroac-
     tively to
	previously published C++ standards.

	  DR	Applied to		Behavior as published		    Cor-
     rect behavior
	LWG  660  C++98       function	objects  for  bitwise	operations   are
     added
