to_ref()

template<product_type Type>

constexpr auto to_ref ( Type &&  t )

related

Creates a kumi::tuple of references given a reference to a kumi::product_type.

Parameters

t	Tuple whose elements are to be referenced.

Returns

A tuple equivalent to the result of kumi::apply([]<typename... T>(T&&... e) { return kumi::forward_as_tuple(std::forward<T>(e)...); }, t)

Example:

 
#include <kumi/kumi.hpp>
#include <iostream>
int main()
{
  auto original = kumi::make_tuple(0,'0',0.f);
  auto ref      = kumi::to_ref( original );
 
  std::cout << original << "\n";
 
  kumi::get<0>(ref) = 9;
  kumi::get<1>(ref) = 'z';
  kumi::get<2>(ref) = 3.14159f;
 
  std::cout << original << "\n";
}
