gul17::FailToInstantiate< T > Class Template Reference

Detailed Description

template<typename T>
class gul17::FailToInstantiate< T >

A helper class to debug types.

This is - on purpose - an incomplete templated class.

Trying to instantiate an object of this class will result in a compiler error with a detailed description of template argument T.

Template Parameters

T	Type to investigate

A using example:

auto t = some_type_or_another{ };
gul17::FailToInstantiate<decltype(t)>{};

A more realistic example for people shying away from auto:

template <typename T>
void my_function(T param)
{
    // wondering if T is what I expect...
    gul17::FailToInstantiate<T>{};
}
