Is there a type-trait to remove top-level cv and reference at once?

Question

I just want to know if there is already one provided by the standard. I know it\'s easy to make one yourself

// for C++03, use  and st         


        

Answer 1

std::decay, I believe, performs this functionality.

Answer 2

I prefer combining the two functionalities since it describes exactly what the intention is:

C++11 std::remove_cv<std::remove_reference<T>::type>::type

C++14 std::remove_cv_t<std::remove_reference_t<T>>

C++20 std::remove_cvref_t<T>
