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

See More

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

Data members

Member object	Definition
parent_ (private)	A pointer to the "parent object" of type ranges::chunk_view* (exposition-only member object*)

Member functions

(constructor) (C++23)	constructs an value_type (public member function)
begin (C++23)	returns the beginning chunk_view::inner-iterator (public member function)
end (C++23)	returns the default sentinel (public member function)
size (C++23)	returns the size of the view (public member function)
Inherited from ranges::view_interface
empty	returns whether the derived view is empty, provided only if it satisfies sized_range or forward_range (public member function of std::ranges::view_interface<D>)
cbegin (C++23)	returns a constant iterator to the beginning of the range (public member function of std::ranges::view_interface<D>)
cend (C++23)	returns a sentinel for the constant iterator of the range (public member function of std::ranges::view_interface<D>)
operator bool	returns whether the derived view is not empty, provided only if ranges::empty is applicable to it (public member function of std::ranges::view_interface<D>)

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

private: // exposition only constexpr explicit value_type( chunk_view& parent );		(since C++23)

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_));
