kumi::as< T > Class Template Reference

Lightweight type-wrapper. More...

#include <kumi/utils/as.hpp>

Detailed Description

template<typename T>
class kumi::as< T >

Lightweight type-wrapper.

kumi::as Wraps type into a constexpr, trivially constructible empty class to optimize passing type parameters via object instead of via template parameters. A specialisation is provided if T is void.

Template Parameters

T	Type to wrap

Example:

#include <kumi/kumi.hpp>
#include <iostream>
 
template<typename T> 
void display (kumi::as<T>)
{
  if constexpr ( std::same_as<T,void>)
    std::cout << "Type is void\n";
  else
    std::cout << "Other type\n";
}
 
int main()
{
  int a = 12;
  display(kumi::as(a));
 
  display(kumi::as<void>{});
}
