std::inplace_vector<T,N>::rend, std::inplace_vector<T,N>::crend - cppreference.com

From cppreference.com

constexpr reverse_iterator rend() noexcept;

 (1) (since C++26)

constexpr const_reverse_iterator rend() const noexcept;

 (2) (since C++26)

constexpr const_reverse_iterator crend() const noexcept;

 (3) (since C++26)

Returns a reverse iterator to the element following the last element of the reversed inplace_vector. It corresponds to the element preceding the first element of the non-reversed inplace_vector. This element acts as a placeholder, attempting to access it results in undefined behavior.

Return value

Reverse iterator to the element following the last element.

Complexity

Constant.

Example

#include <algorithm>
#include <iostream>
#include <inplace_vector>

int main()
{
    std::inplace_vector<int, 11> a{1, 11, 11, 35, 0, 12, 79, 76, 76, 69, 40};

    // Print elements of container in reverse order using const_reverse_iterator's.
    std::for_each(a.crbegin(), a.crend(), [](int e){ std::cout << e << ' '; });
    std::cout << '\n';

    // Modify each element of container using non-const reverse_iterator's.
    std::for_each(a.rbegin(), a.rend(), [](int& e){ e += 32; });

    // Print elements as chars in reverse order using const_reverse_iterator's.
    std::for_each(a.crbegin(), a.crend(), [](char e){ std::cout << e; });
    std::cout << '\n';
}

Output: 

40 69 76 76 79 12 0 35 11 11 1
