Detailed Description

   template<typename _CharT, typename _Traits = std::char_traits<_CharT>>
       class std::basic_string_view< _CharT, _Traits >" A non-owning reference to a string.

       Template Parameters
           _CharT Type of character
           _Traits Traits for character type, defaults to char_traits<_CharT>.

       A basic_string_view looks like this:

       _CharT*    _M_str
       size_t     _M_len
