Notes

In addition to being included in <iterator>, std::rend is guaranteed to become available if any of the following headers are included: <array>, <deque>, <forward_list>, <list>, <map>, <regex>, <set>, <string>, <unordered_map>, <unordered_set>, and <vector>.

Specializations

Custom specializations of std::rend may be provided for classes that do not expose a suitable rend() member function, yet can be iterated. The following specializations are already provided by the standard library:

specializes std::rend
(function) [edit]
specializes std::rend()
(function) [edit]
