all_unique()

template<product_type T>

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

inlineconstexpr

Return the product type containing the values of the first occurence of each type in the input product type.

Parameters

t	Product type to process

Returns

A product type built by keeping the first occurrence of every distinct element type in the input product type.

Helper type

namespace kumi
{
  template<product_type T> struct all_unique;
 
  template<product_type T>
  using all_unique_t = typename all_unique<T>::type;
}

Computes the type returned by a call to kumi::all_unique.

Example:

 
#include <kumi/kumi.hpp>
#include <iostream>
 
int main()
{
    using tuple = kumi::tuple<int, int, char, int, float, float>;
 
    tuple a = {1, 2, 'x', 3, 1.f, 2.f};
 
    std::cout << kumi::all_unique(a) << "\n";
}
