namespace std::ranges { template<forward_range V, forward_range Pattern> requires view<V> && view<Pattern> && indirectly_comparable<iterator_t<V>, iterator_t<Pattern>, ranges::equal_to> struct split_view<V, Pattern>::sentinel { private: sentinel_t<V> end_ = sentinel_t<V>(); // exposition only public: sentinel() = default; constexpr explicit sentinel(split_view& parent); friend constexpr bool operator==(const iterator& x, const sentinel& y); }; }

constexpr explicit sentinel(split_view& parent);
1
#
Effects: Initializes end_ with ranges​::​end(parent.base_).
🔗
friend constexpr bool operator==(const iterator& x, const sentinel& y);
2
#
Effects: Equivalent to: return x.cur_ == y.end_ && !x.trailing_empty_;
