std::ranges...perator*,->(3)

💅 std::ranges...perator*,->(3) 💅

okay so bestie, this page is from the C++ Standard Libary manual (yes, that’s how it’s spelled here, no cap), and it’s all about the operator* and operator-> for std::ranges::join_view::iterator. Very niche, very main character, but we’re gonna get through it together.

🌸 NAME 🌸

• std::ranges::join_view::iterator::operator*,-> — and the short description is literally std::ranges::join_view::iterator::operator*,-> too. The page says it twice, so we’re saying it twice. Periodt.

🌀 Synopsis 🌀

          constexpr decltype(auto) operator*() const;                      (1)
       (since C++20)
          constexpr InnerIter operator->() const                           (2)
       (since C++20)
            requires /*has-arrow*/<InnerIter> && std::copyable<InnerIter>;

Two overloads, both since C++20. Overload (2) has that requires clause: /*has-arrow*/<InnerIter> && std::copyable<InnerIter>; — don’t skip it, bestie.

Returns the element the underlying iterator inner_ points to.

1. (1) is equivalent to return *inner_;.
2. (2) is equivalent to return inner_;.

🍓 Parameters 🍓

• Parameters: (none) — literally zero parameters. Not one. Nada. 💅

🎀 Return value 🎀

• Return value: the current element. That’s it. That’s the vibe.

🌈 Example 🌈

This section is incomplete.

Reason: no example.

Not me crying because there’s no example 😭. Anyway.

👑 Category 👑

• * Todo no example — yeah, it’s a todo and there’s no example. We move.
