constexpr V base() const& requires std::copy_constructible<V>;	(1)	(since C++23)
constexpr V base() &&;	(2)	(since C++23)

Returns a copy of the underlying view base_.

1) Copy constructs the result from the underlying view. Equivalent to: return base_;

2) Move constructs the result from the underlying view. Equivalent to: return std::move(base_);

Parameters

(none)

Return value

A copy of the underlying view.

Run this code

#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());
}

Output:

 1 2 3 4 5
 5 4 3 2 1
