推導指引

 

constexpr auto end() const;		(C++20 起)

返回一個表示結果子範圍末尾的迭代器或哨兵。等價於

constexpr auto end()
{
    if constexpr (ranges::common_range<V>)
        return iterator{*this, ranges::end(base_), {}};
    else
        return sentinel{*this};
}

返回值

一個迭代器或一個哨兵。

示例

執行此程式碼

#include <cassert>
#include <ranges>
#include <string_view>
 
int main()
{
    constexpr std::string_view keywords{"bitand bitor bool break"};
    std::ranges::split_view kw{keywords, ' '};
    assert(4 == std::ranges::distance(kw.begin(), kw.end()));
}
