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 opera- tor| 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 argument and (C++14) return types (class template specialization) Member types Type Defini- tion 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; } http://cppreference.com 2022.07.31 std::bit_or(3)
