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

🎀 NAME 🎀

okay so welcome to std::ranges...r::operator*(3) — the std::ranges::stride_view::iterator::operator* page from the C++ Standard Libary (their spelling, not mine 💅), manual section 3.

• std::ranges::stride_view::iterator::operator*
• std::ranges::stride_view::iterator::operator*

yep, the NAME section lists it twice, and we are not erasing one — both stay, bestie 💖

---

🦋 Synopsis 🦋

constexpr decltype(auto) operator*() const;  (since C++23)

Returns the elements into V the underlying iterator current_ points to.

Equivalent to: return *current_;.

---

🎀 Parameters 🎀

(none) — literally no parameters, not a single one 🫶

---

💖 Return value 💖

The current element. That's it. That's the whole vibe ✨

---

🌸 Notes 🌸

operator-> is not provided.

no operator->, no cap. it's giving "you get the dereference and that's the whole story" 💀

---

🔥 Example 🔥

// Run this code

#include <ranges>

int main()
{
    constexpr static auto v = {'a', 'b', 'c', 'd', 'e'};
    constexpr auto view{v | std::views::stride(2)};
    constexpr auto iter{view.begin() + 1};
    static_assert(*iter == 'c');
    static_assert(*(view.begin() + 2) == 'e');
}
