as_flat_ptr()

template<product_type Tuple>

KUMI_TRIVIAL_NODISCARD auto kumi::as_flat_ptr ( Tuple &&  ts )

noexcept

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

Parameters

ts	Tuple to convert

Returns

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

Helper type

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

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

Example

 
#include <kumi/tuple.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 ptr) { *ptr += 5; }, ptr );
 
  std::cout << a << "\n";
}
