std::ranges::adjacent_view<V,N>:: iterator <Const>:: operator*

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_);

Parameters

(none)

Return value

The current element, which is a std::tuple of references to underlying elements.

Notes

operator - > is not provided.

Example

#include <ranges>
#include <tuple>
 
int main()
{
    constexpr static auto v = {0, 1, 2, 3, 4, 5};
    //                               └──┬──┘
    //                                  └─────────────────┐
    constexpr auto view {v | std::views::adjacent<3>}; // │
    constexpr auto iter {view.begin() + 2};            // │
    //              ┌────────────────────┬────────────────┘
    //              │                 ┌──┴──┐
    static_assert(*iter == std::tuple{2, 3, 4});
}
