transpose()

template<product_type T>
requires ( _::supports_transpose<T> )

constexpr auto kumi::transpose ( T &&  t )

inlineconstexpr

Transpose a product type of product types by shifting elements in their transposed position always returning a tuple as the external product type.

Parameters

t	Product type to transpose

Returns

A tuple containing the transposed elements of t.

Helper type

namespace kumi::result
{
  template<product_type T> struct transpose;
 
  template<product_type T>
  using transpose_t = typename transpose<T>::type;
}

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

Example

 
#include <kumi/kumi.hpp>
#include <iostream>
 
int main()
{
  auto values = kumi::tuple { kumi::tuple{ 1, 'a', 0.1   }
                            , kumi::tuple{ 2, 'b', 0.01  }
                            };
 
  auto r = kumi::transpose(values );
  std::cout << r << "\n";
}
