std::ranges...r::operator*(3)

🎀 NAME 🎀

okay so we're in the C++ Standard Libary manual (yes, that's how it's spelled up top 💅), on the page for std::ranges::adjacent_view::iterator::operator* — footer name std::ranges...r::operator*(3), if you're keeping track.

And the NAME section literally says std::ranges::adjacent_view::iterator::operator* again. Double name, double slay ✨

💅 Synopsis 💅

The signature is a whole mood:

constexpr auto operator*() const;

(since C++23) — this one's tagged as C++23, bestie. Not before, no cap.

🌸 Parameters 🌸

(none) — zero, nada, nothing to pass in 🫶

🦋 Return value 🦋

The current element, which is a std::tuple of references to underlying elements. So it's giving tuple-of-refs energy, lowkey iconic.

⭐ Notes ⭐

operator-> is not provided. That's the whole note. No arrow, no cap, it's just not provided 💀

🔥 Example 🔥

Run this code, bestie:

// Run this code

#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});
}
