reverse()

template<concepts::product_type Tuple>

auto kumi::reverse ( Tuple && t )

inlinenodiscardconstexpr

Reverse elements of a kumi::product_type.

Parameters

t	kumi::product_type to reverse

Returns

A tuple equivalent to kumi::make_tuple(t[index<size_v<T> - 1 - Idx>]...);

Helper type

namespace kumi::result
{
  template<product_type Tuple> struct reverse;
 
  template<product_type Tuple>
  using reverse_t = typename reverse<Tuple>::type;
}

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

Examples:

#include <kumi/kumi.hpp>
#include <iostream>
 
int main()
{
  auto values = kumi::tuple { 1, 'a', 0.1 };
 
  std::cout << values << "\n";
  std::cout << kumi::reverse(values) << "\n";
}

#include <kumi/kumi.hpp>
#include <iostream>
 
int main()
{
  using namespace kumi::literals;
 
  auto values = kumi::record { "a"_id = 1, "b"_id = 'a', "c"_id = 0.1 };
 
  std::cout << values << "\n";
  std::cout << kumi::reverse(values) << "\n";
}
