bit_or() [2/2]

template<product_type Tuple, typename Value >

constexpr auto kumi::bit_or ( Tuple &&  t, Value  init  )

constexpr

Computes the bitwise OR of all elements.

Parameters

t	Tuple to operate on
init	Initial value of the product

Returns

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

Helper type

namespace kumi::result
{
  template<product_type Tuple, typename Value> struct bit_or;
 
  template<product_type Tuple, typename Value>
  using prod_t = typename bit_or_t<Tuple,Value>::type;
}

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

Example

 
#include <kumi/tuple.hpp>
#include <iostream>
 
int main()
{
  auto t = kumi::tuple{1,short{8},' ', 4ULL};
 
  std::cout << kumi::bit_or(t, 0) << "\n";
  std::cout << kumi::bit_or(t) << "\n";
}
