Return value
A copy of the underlying view.
Example
Run this code
#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::take_while([](int x){ return x < 4; });
stq::println("{}", view);
const auto base = view.base();
stq::println("{}", base);
}
Output:
