1) Let derived be a reference bound to static_cast<D&>(*this).
Equivalent to return ranges::cbegin(derived);.
2) Same as (1), except that derived is static_cast<const D&>(*this).

Parameters¶

(none)

Return value¶

A constant beginning iterator of the range.

All range adaptors and range factories in the standard library and
std::ranges::subrange use the default implementation of cbegin.
