std::ranges...:operator[](3)

💅 NAME

okay so bestie, welcome to std::ranges...:operator[](3) — that's the page from the C++ Standard Libary manual, and it's literally all about std::ranges::adjacent_transform_view::iterator::operator[] and also std::ranges::adjacent_transform_view::iterator::operator[]. same thing, no cap 💖

✨ Synopsis

          constexpr decltype(auto) operator[]( difference_type n ) const
       (since C++23)
              requires ranges::random_access_range<Base>;

so yeah, it returns an element at the specified relative location. parent_ and inner_ are the data members of the iterator, and this is equivalent to:

        return apply([&](const auto&... iters) -> decltype(auto)
                     {
                        return invoke(*parent_->fun_, iters[n]...);
                     },
                     inner_.current_);

🎀 Parameters

• n — position relative to current location

🦋 Return value

The element at displacement n relative to the current location. slay ✨
