bit_and() [2/2]

template<product_type T, typename Value >

constexpr auto kumi::bit_and ( T &&  t, Value  init  )

inlineconstexpr

Computes the bitwise AND of all elements.

Parameters

t	Product type to operate on
init	Optional initial value of the reduction

Returns

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

Helper type

namespace kumi::result
{
  template<product_type T, typename Value> struct bit_and;
 
  template<product_type T, typename Value>
  using bit_and_t = typename bit_and<T,Value>::type;
}

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

Example

 
#include <kumi/kumi.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";
}
