= typename invoke_result<Func, TArgs...>::type¶ Helper for carb::cpp17::invoke_result which accesses the
type
member.// Get the proper return type and SFINAE-safe disqualify `foo` when `f(10)` is not valid. template <typename Func> invoke_result_t<Func, int> foo(Func&& f) { return invoke(std::forward<Func>(f), 10); }
This is equivalent to the C++
std::invoke_result_t
helper typedef.
