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

Function object for performing bitwise AND. Effectively calls operator& on type T.

Specializations

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

(since C++14)

Member types

Type	Definition
result_type(deprecated in C++17)	T
first_argument_type(deprecated in C++17)	T
second_argument_type(deprecated in C++17)	T

Member functions

operator()

returns the result of bitwise AND of two arguments (public member function)

std::bit_and::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 AND of lhs and rhs.

Parameters

lhs, rhs

-

values to compute bitwise AND of

Return value

The result of lhs & rhs.

Exceptions

(none)

Possible implementation

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