constexpr reverse_iterator rbegin() noexcept();
constexpr const_reverse_iterator rbegin() const noexcept();
constexpr const_reverse_iterator crbegin() const noexcept();

Returns an iterator to the first element of the reversed container. It corresponds to the last element of the non-reversed container. If the container is empty, the returned iterator will be equal to rend()

(none)

Reverse iterator to the first element.

Constant.

#include <haz/SharedQueue.hpp>
#include <iostream>

int main() {
    haz::SharedQueue<int, 10> queue{ 0, 1, 2, 3 };
    for(typename haz::SharedQueue<int, 10>::reverse_iterator it = queue.rbegin(); it != queue.rend(); ++it)
        std::cout << *it << ", ";
    std::cout << '\n';
}

Output:

3, 2, 1, 0,
