NAME¶

std::ranges::chunk_view::begin - std::ranges::chunk_view::begin

Synopsis¶

V models only input_range
constexpr __outer_iterator begin(); (1) (since C++23)
V models forward_range
constexpr auto begin() requires (!__simple_view<V>); (2) (since C++23)
constexpr auto begin() const requires ranges::forward_range<const (3) (since C++23)
V>;

Returns an iterator to the first element of the chunk_view.

Let base_ denote the underlying view.
1) Available only if V models input_range. Equivalent to:

current_ = ranges::begin(base_);
remainder_ = n_;
return __outer_iterator(*this);

current_, remainder_, and n_ are underlying exposition only data members of
chunk_view.
2) Available if V models forward_range. Equivalent to: return iterator<false>(this,
ranges::begin(base_));, where iterator is exposition only nested class.
3) Available if V models forward_range. Equivalent to: return iterator<true>(this,
ranges::begin(base_));, where iterator is exposition only nested class.

Parameters¶

(none)

Return value¶

An iterator to the first element of the chunk_view, as described above.
