std::ranges...r::iterator(3)

💖 std::ranges...r::iterator(3) 💖

okay so bestie, this is the std::ranges...r::iterator(3) page from the C++ Standard Libary manual — yes, “Libary” is literally how it’s spelled in the header, iykyk 😭💅. We’re talking about the constructor for std::ranges::stride_view::iterator::iterator, and we are gonna get through every signature, every requirement, every tiny private little detail together. Periodt. ✨

✨ NAME ✨

std::ranges::stride_view::iterator::iterator — std::ranges::stride_view::iterator::iterator

It’s giving constructor energy, fr fr. 🫶

🌸 SYNOPSIS 🌸

          /*iterator*/()
              requires std::default_initializable<ranges::iterator_t<Base>> (1)
       (since C++23)
          = default;
          constexpr /*iterator*/( /*iterator*/<!Const> i )

              requires Const and
                  std::convertible_to<ranges::iterator_t<V>,                (2)
       (since C++23)
          ranges::iterator_t<Base>> and

                  std::convertible_to<ranges::sentinel_t<V>,
          ranges::sentinel_t<Base>>;
          private:

          constexpr /*iterator*/( /*Parent*/& parent,
       (exposition
                                  ranges::iterator_t<Base> current,         (3)
       only*)

                                  ranges::range_difference_t<Base> missing
          = 0 );

Constructs an iterator. That’s the whole vibe of this page, no cap. 🦋

🌟 Constructs an iterator 🌟

1. Default constructor. It value-initializes:
   • current_ with ranges::iterator_t<Base>(),
   • end_ with ranges::sentinel_t<Base>(),
   • stride_ with 0,
   • missing_ with 0.
2. Conversion from /*iterator*/<false> to /*iterator*/<true>. Initializes:
   • current_ with std::move(i.current_),
   • end_ with std::move(i.end_),
   • stride_ with i.stride_,
   • missing_ with i.missing_.
3. A private constructor which is used by stride_view::begin and stride_view::end. This constructor is not accessible to users. Initializes:
   • current_ with std::move(current),
   • end_ with ranges::end(parent->base_),
   • stride_ with parent->stride_,
   • missing_ with missing.

bestie, that third one is private — not accessible to users — so don’t try to slide into its DMs 🙈💀.

💅 PARAMETERS 💅

• i — an /*iterator*/<false>
