(2) (since C++20)

Returns a copy of the underlying view.

2) Move constructs the result from the underlying view base_.

Return value

A copy of the underlying (adapted) view base_.

Example

#include <iostream>
#include <ranges>

namespace stq {
void println(auto, const auto& v)
{
    for (const auto& e : v)
        std::cout << e << ' ';
    std::cout << '\n';
}
}

int main()
{
    static constexpr int a[]{1, 2, 3, 4, 5};
    constexpr auto view = a | std::views::drop(2);
    stq::println("{}", view);
    const auto base = view.base();
    stq::println("{}", base);
}
