to_ref() [1/2]

template<concepts::record_type R>

auto kumi::to_ref ( R && r )

inlinenodiscardconstexpr

Creates a kumi::record of references given a reference to a kumi::record_type.

Parameters

r	Record whose elements are to be referenced.

Returns

A record equivalent to the result of kumi::apply([]<typename... T>(T&&... e) { return kumi::forward_as_record<name_of(as<T>{})...>(std::forward<T>(e)...); }, t)

Example:

#include <kumi/kumi.hpp>
#include <iostream>
int main()
{
  using namespace kumi::literals;
  auto original = kumi::make_record("a"_id=0,"b"_id='0',"c"_id=0.f);
  auto ref      = kumi::to_ref( original );
 
  std::cout << original << "\n";
 
  kumi::get<"a">(ref) = 9;
  kumi::get<"b">(ref) = 'z';
  kumi::get<"c">(ref) = 3.14159f;
 
  std::cout << original << "\n";
}
