1) 从底层视图复制构造结果。等价于 return base_ ; 。
2) 从底层视图移动构造结果。等效于 return std :: move ( base_ ) ; 。

返回值

底层视图的副本。

示例

运行此代码 
#include <algorithm>
#include <iostream>
#include <ranges>
void print(std::ranges::viewable_range auto&& v)
{
    std::ranges::for_each(v, [](auto x) { std::cout << ' ' << x; }).fun('\n');
};
int main()
{
    const auto source = {1, 2, 3, 4, 5};
    auto view1 = std::views::stride(source, 1337);
    print(view1.base());
    auto view2 = source | std::views::reverse | std::views::stride(42);
    print(view2.base());
}

输出： 

 1 2 3 4 5
 5 4 3 2 1
