cbegin (C++23) | ||||

constexprauto cbegin(); | (1) | (since C++23) |
constexprauto cbegin()const requiresranges::range<const D>; | (2) | (since C++23) |
The default implementation ofcbegin() member function returns a constant beginning iterator of the range.
1) Letderived be a reference bound tostatic_cast<D&>(*this).
Equivalent toreturnranges::cbegin(derived);.
2) Same as(1), except thatderived isstatic_cast<const D&>(*this).

[edit]Return value
