                    |   constexpr auto cend();  | 
(1) | (since C++23) | 
|   constexpr auto cend() const requires ranges::range<const D>;  | 
(2) | (since C++23) | 
The default implementation of cend() member function returns the sentinel for the constant iterator of the range.
1) Let derived be a reference bound to static_cast<D&>(*this). Equivalent to return ranges::cend(derived);.
2) Same as (1), except that derived is static_cast<const D&>(*this).
Parameters
(none)
Return value
The sentinel for the constant iterator of the range.
Notes
All range adaptors and range factories in the standard library and std::ranges::subrange use the default implementation of cend.
