## Struct charconv

boost::cnv::charconv — std::to/from_chars-based extended converter

## Synopsis

    // In header: <boost/convert/charconv.hpp>

    struct charconv : public boost::cnv::cnvbase< boost::cnv::charconv > {
      // types
      typedef boost::cnv::charconv             this_type;
      typedef boost::cnv::cnvbase< this_type > base_type;

      // public member functions
      template<typename in_type>
        cnv::range< char * > to_str(in_type, char *) const;
      template<typename string_type, typename out_type>
        void str_to(cnv::range< string_type >, optional< out_type > &) const;
      std::chars_format chars_format() const;
    };

## Description

Good overall performance and moderate formatting facilities.

### `charconv` public member functions

1.     template<typename in_type>
         cnv::range< char * > to_str(in_type value_in, char * buf) const;

2.     template<typename string_type, typename out_type>
         void str_to(cnv::range< string_type > range,
                     optional< out_type > & result_out) const;

3.     std::chars_format chars_format() const;
