std::ranges...it_view::end(3)

💅 std::ranges::lazy_split_view::end 💅

okay bestie, this page comes from the C++ Standard Libary, manual section 3 — yes, that's the exact spelling on the page, we're not fixing it 😭💖 It's the end member of std::ranges::lazy_split_view, and we're about to get you fully caught up ✨

---

🌸 NAME 🌸

std::ranges::lazy_split_view::end — std::ranges::lazy_split_view::end (it's giving "same name on both sides" and honestly? iconic 😌)

✨ Synopsis ✨

Here's the signature situation, no cap:

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;

🎀 Parameters 🎀

(none) — literally zero parameters, bestie 🫶

💖 Return value 💖

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

🦋 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
