(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.

Example

Run this code 
#include <algorithm>
#include <functional>
#include <ranges>
 
int main()
{
    static constexpr auto v = {1, 1, 2, 2, 3, 3, 3};
    constexpr auto chunks = v | std::views::chunk_by(std::equal_to{});
    static_assert(std::ranges::equal(v, chunks.base()));
}
