template<class...> using void_t=void; | (library fundamentals TS v2) | |
A utility metafunction that maps a sequence of any types to the typevoid.
This utility metafunction is used in template metaprogramming to detect ill-formed types inSFINAE context. First voted into C++17 asstd::void_t, it was later added as well to the library fundamentals TS asstd::experimental::void_t, because it is a dependency of thedetection idiom and the LFTS v2 is based on C++14.
