💖 std::ranges...::value_type 💖

okay so bestie, we're in the C++ Standard Libary manual — yes, that's the manual name and that's how it's spelled in the header, and honestly? iconic — and this page is all about std::ranges::chunk_view::outer-iterator::value_type. stay with me, it's niche but it slays.

🌸 NAME 🌸

std::ranges::chunk_view::outer-iterator::value_type — std::ranges::chunk_view::outer-iterator::value_type.

✨ Synopsis ✨

Defined in header <ranges>
struct value_type : view_interface<value_type>  (since C++23)

A value type of the iterator chunk_view::outer-iterator, formed when V models input_range.

🎀 Member functions 🎀

💅 the ones it brings itself

  • constructor — constructs an value_type (C++23) — public member function.
  • begin — returns the beginning chunk_view::inner-iterator (C++23) — public member function.
  • end — returns the default sentinel (C++23) — public member function.
  • size — returns the size of the view (C++23) — public member function.

👑 Inherited from std::ranges::view_interface 👑

  • empty — returns whether the derived view is empty. Provided if it satisfies sized_range or forward_range. (C++20) — public member function of std::ranges::view_interface<D>.
  • cbegin — returns a constant iterator to the beginning of the range. (C++23) — public member function of std::ranges::view_interface<D>.
  • cend — returns a sentinel for the constant iterator of the range. (C++23) — public member function of std::ranges::view_interface<D>.
  • operator bool — returns whether the derived view is not empty. Provided if ranges::empty is applicable to it. (C++20) — public member function of std::ranges::view_interface<D>.

🧸 std::ranges::chunk_view::outer-iterator::value_type::value_type

private:

// exposition only                                    (since C++23)

constexpr explicit value_type( chunk_view& parent );

Constructs the value_type object so that parent_ is initialized with std::addressof(parent).

Parameters

  • parent — the chunk_view object.

🦋 std::ranges::chunk_view::outer-iterator::value_type::begin

constexpr /*inner-iterator*/ begin() const noexcept;  (since C++23)

Equivalent to return /*inner-iterator*/(*parent_);.

🍓 std::ranges::chunk_view::outer-iterator::value_type::end

constexpr std::default_sentinel_t end() const noexcept;  (since C++23)

Equivalent to return std::default_sentinel;.

🌈 std::ranges::chunk_view::outer-iterator::value_type::size

constexpr auto size() const
    requires std::sized_sentinel_for<ranges::sentinel_t<V>,
                                     ranges::iterator_t<V>>;

(since C++23)

Returns the size of the view.

Equivalent to:

return /*to-unsigned-like*/(
    ranges::min(parent_->remainder_, ranges::end(parent_->base_) -
*parent_->current_));
