std::experimental::void_t (3) Linux Manual Page

std::experimental::void_t – std::experimental::void_t

Synopsis

Defined in header<experimental / type_traits>

    template <class...>
    (library fundamentals TS v2)

        using void_t = void;

A utility metafunction that maps a sequence of any types to the type void.

Notes

This utility metafunction is used in template metaprogramming to detect ill-formed types in SFINAE context. First voted into C++17 as std::void_t, it was later added as well to the library fundamentals TS as std::experimental::void_t, because it is a dependency of the detection_idiom.
