std::basic_string_view<CharT,Traits>::rbegin, std::basic_string_view<CharT,Traits>::crbegin

Since C++17

Returns a reverse iterator to the first character of the reversed view. It corresponds to the last character of the non-reversed view.

# Declarations

constexpr const_reverse_iterator rbegin() const noexcept;

(since C++17)

constexpr const_reverse_iterator crbegin() const noexcept;

(since C++17)

# Return value

const_reverse_iterator to the first character.

# Example

#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(), std::next(str_view.rbegin(), 3), out_it);
    *out_it = '\n';
 
    std::copy(str_view.crbegin(), std::next(str_view.crbegin(), 3), out_it);
    *out_it = '\n';
}
