push_back()

template<concepts::product_type Tuple, typename T>

auto kumi::push_back ( Tuple && t, T && v )

inlinenodiscardconstexpr

Constructs a tuple by adding a value v at the end of t.

Parameters

t	Base tuple
v	Value to insert in front of t

Returns

A tuple composed of all elements of t in order followed by v.

Helper type

namespace kumi::result
{
  template<product_type Tuple, typename T> struct push_back;
 
  template<product_type Tuple, typename T>
  using push_back_t = typename push_back<Tuple,T>::type;
}

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

Examples:

#include <kumi/kumi.hpp>
#include <iostream>
 
int main()
{
  std::cout << kumi::push_back( kumi::tuple{}, 63.21)  << "\n";
 
  kumi::tuple t{1,2.,3.4f};
  std::cout << t                          << "\n";
  std::cout << kumi::push_back(t, 'Z')   << "\n";
}

#include <kumi/kumi.hpp>
#include <iostream>
 
int main()
{
  using namespace kumi::literals;
 
  std::cout << kumi::push_back( kumi::record{}, "a"_id = 63.21)  << "\n";
 
  kumi::record t{"a"_id = 1,"b"_id = 2.,"c"_id = 3.4f};
  std::cout << t                          << "\n";
  std::cout << kumi::push_back(t, "d"_id = 'Z')   << "\n";
}
