成员函数

operator()
lhs rhs 应用 operator&
(公开成员函数)

std::bit_and<void>:: operator()

template < class T, class U >

constexpr auto operator ( ) ( T && lhs, U && rhs ) const

- > decltype ( std:: forward < T > ( lhs ) & std:: forward < U > ( rhs ) ) ;

返回 std:: forward < T > ( lhs ) & std:: forward < U > ( rhs ) 的结果。

参数

lhs, rhs - 要进行按位与运算的值

返回值

std:: forward < T > ( lhs ) & std:: forward < U > ( rhs )
