constexpr auto end() requires ranges::forward_range<V> && ranges::common_range<V>;
(1) (since C++20)
constexpr auto end() const;
(2) (since C++20)
1) Returns an iterator representing the end of the view.

Equivalent to:

return /*outer_iterator*/</*simple_view*/<V>>{*this, ranges::end(base_)};.
2) Returns an outer_iterator or a std::default_sentinel representing the end of the view.

Equivalent to:

if constexpr (ranges::forward_range<V> && ranges::forward_range<const V> &&
              ranges::common_range<const V>)
    return /*outer_iterator*/<true>{*this, ranges::end(base_)};
else
    return std::default_sentinel;

(none)

[edit] Return value

An outer_iterator or a std::default_sentinel representing the end of the view.

[edit] Example

#include <iostream>
#include <ranges>
#include <string_view>
 
int main()
{
    constexpr std::string_view keywords{ "false float for friend" };
    std::ranges::lazy_split_view kw{ keywords, ' ' };
    const auto count = std::ranges::distance(kw.begin(), kw.end());
    std::cout << "Words count: " << count << '\n';
}

Output:

Words count: 4
