template<product_type Tuple>

constexpr auto kumi::pop_front ( Tuple &&  t )

inlineconstexpr

Remove the first (if any) element of a kumi::product_type.

Parameters

t	Base tuple

Returns

A tuple composed of all elements of t except its first. Has no effect on empty t.

Helper type

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

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

Example

 
#include <kumi/kumi.hpp>
#include <iostream>
 
int main()
{
  std::cout << kumi::pop_front( kumi::tuple{} )  << "\n";
 
  kumi::tuple t{1,2.,3.4f};
  std::cout << t                    << "\n";
  std::cout << kumi::pop_front(t)   << "\n";
}
