flatten()

template<product_type Tuple>

constexpr auto kumi::flatten ( Tuple const &  ts )

constexpr

Converts a tuple of tuples into a tuple of all elements.

Parameters

ts	Tuple to flatten

Returns

A tuple composed of all elements of t flattened non-recursively

Helper type

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

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

Example

 
#include <kumi/tuple.hpp>
#include <iostream>
 
int main()
{
  auto nbrs       = kumi::tuple{1,2,3};
  auto more_nbrs  = kumi::tuple{0,nbrs,4};
  auto ltrs       = kumi::tuple{'a','b','c'};
 
  auto r = kumi::flatten( kumi::tuple{3.5,nbrs,'z',more_nbrs,5.35f,ltrs} );
  std::cout << r << "\n";
}
