bit_and() [1/2]

template<product_type Tuple>

constexpr auto kumi::bit_and ( Tuple &&  t )

constexpr

Computes the bitwise AND of all elements.

Parameters

t	Tuple to operate on

Returns

The value of get<0>(t) & ... & get<N-1>(t)

Helper type

namespace kumi::result
{
  template<product_type Tuple> struct bit_and;
 
  template<product_type Tuple>
  using prod_t = typename bit_and_t<Tuple>::type;
}

Computes the return type of a call to kumi::bit_and

Example

 
#include <kumi/tuple.hpp>
#include <iostream>
 
int main()
{
  auto t = kumi::tuple{14,short{7}, 255ULL};
 
  std::cout << kumi::bit_and(t, 65535) << "\n";
  std::cout << kumi::bit_and(t) << "\n";
}
