NAME
std::basic_string_view<CharT,Traits>::rend,std::basic_string_view<CharT,Traits>::crend - std::basic_string_view<CharT,Traits>::rend,std::basic_string_view<CharT,Traits>::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';
}
