std::basic_string_view::rend,std::basic_string_view::crend(3)

NAME
std::basic_string_view::rend,std::basic_string_view::crend - std::basic_string_view::rend,std::basic_string_view::crend

Synopsis
   constexpr const_reverse_iterator rend() const noexcept; (since C++17)
   constexpr const_reverse_iterator crend() const noexcept; (since C++17)
   Returns a reverse iterator to the character following the last character of the
   reversed view. It corresponds to the character preceding the first character of the
   non-reversed view. This character acts as a placeholder, attempting to access it
   results in undefined behavior.

Parameters
   (none)

Return value
   const_reverse_iterator to the character following the last character.

Complexity
   Constant.

Example
// Run this code
 #include <algorithm>
 #include <iostream>
 #include <iterator>
 #include <string_view>
 int main()
 {
     std::ostream_iterator<char> out_it(std::cout);
     std::string_view str_view("abcdef");
     std::copy(str_view.rbegin(), str_view.rend(), out_it);
     *out_it = '\n';
     std::copy(str_view.crbegin(), str_view.crend(), out_it);
     *out_it = '\n';
 }

Output:
 fedcba
