      The header <boost/utility/ostream_string.hpp> provides the function template
      boost::ostream_string for formatted output that
      satisfies the requirements of [ostream.formatted.reqmts].
    
      The inserter for class template basic_string_view
      could be implemented as follows:
    
template<class charT, class traits> std::basic_ostream<charT, traits>& operator<<(std::basic_ostream<charT, traits>& os, const basic_string_view<charT, traits>& str) { return boost::ostream_string(os, str.data(), str.size()); }
namespace boost { template<class charT, class traits> std::basic_ostream<charT, traits>& ostream_string(std::basic_ostream<charT, traits>& os, const charT* data, std::size_t size); } /* boost */
template<class charT, class traits> std::basic_ostream<charT, traits>& ostream_string(std::basic_ostream<charT, traits>&
        os, const charT* data, std::size_t size);
                  Behaves like a formatted inserter (as described in [ostream.formatted.reqmts])
                  of os. Creates
                  a character sequence seq
                  of size characters
                  starting at data,
                  each widened using os.widen() ([basic.ios.members]). Determines
                  padding for seq
                  as described in [ostream.formatted.reqmts]. Inserts seq into os.
                  Calls width(0).
                
                  os.
                
basic_string_ref
          and basic_string_view stream
          insertion operators to write directly to the basic_streambuf
          and refactored that functionality into this common utility.
