std::ranges::chunk_view<V>::begin
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 V>; | (3) | (since C++23) |
Returns an iterator to the first element of the chunk_view.
1) Available only if
V models input_range. Equivalent to current_ =ranges::begin(base_);
remainder_ = n_;
return outer_iterator(*this);
2) Available if
V models forward_range. Equivalent to return iterator<false>(this,ranges::begin(base_));.
3) Available if
V models forward_range. Equivalent to return iterator<true>(this,ranges::begin(base_));.Return value
An iterator to the first element of the chunk_view, as described above.
