constexpr auto operator*() const; | (since C++23) |
Returns the elements into V the underlying array of iterators points to.
Let current_ be an underlying array of iterators.
Equivalent to:
return __tuple_transform([](auto& i) -> decltype(auto) { return *i; }, current_);(none).
The current element, which is a std::tuple of references to underlying elements.
operator-> is not provided.
