as_flat_ptr()

template<product_type T>

auto kumi::as_flat_ptr ( T &&  t )

inlinenoexcept

Convert a kumi::product_type to a flat product type of pointers to each its components.

Parameters

t	Product type to convert

Returns

A flat product_type composed of pointers to each elements of t.

Helper type

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

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

Example

 
#include <kumi/kumi.hpp>
#include <iostream>
 
int main()
{
  kumi::tuple a = { 1, kumi::tuple{ 2.3, 4.5f }, short{89} };
 
  auto ptr = kumi::as_flat_ptr(a);
 
  std::cout << a << "\n";
  std::cout << ptr << "\n";
 
  kumi::for_each([](auto p) { *p += 5; }, ptr );
 
  std::cout << a << "\n";
}
