template<bool_DecOnly,typename_Tp>constexprboolstd::__detail::__from_chars_alnum(constchar*&__first,constchar*__last,_Tp&__val,int__base)[constexpr]
       std::from_chars implementation for integers in any base. If _DecOnly is true, then we may assume __base
       is at most 10.

   template<bool_DecOnly,typename_Tp>constexprboolstd::__detail::__from_chars_pow2_base(constchar*&__first,constchar*__last,_Tp&__val,int__base)[constexpr]
       std::from_chars implementation for integers in a power-of-two base. If _DecOnly is true, then we may
       assume __base is at most 8.

   template<typename_CharT,typename_Traits,typename_String>std::basic_ostream<_CharT,_Traits>&std::__detail::operator<<(std::basic_ostream<_CharT,_Traits>&__os,const_Quoted_string<_String,_CharT>&__str)
       Inserter for quoted strings.

   template<typename_CharT,typename_Traits>std::basic_ostream<_CharT,_Traits>&std::__detail::operator<<(std::basic_ostream<_CharT,_Traits>&__os,const_Quoted_string<const_CharT*,_CharT>&__str)
       Inserter for quoted strings.

   template<typename_CharT,typename_Traits,typename_Alloc>std::basic_istream<_CharT,_Traits>&std::__detail::operator>>(std::basic_istream<_CharT,_Traits>&__is,const_Quoted_string<basic_string<_CharT,_Traits,_Alloc>&,_CharT>&__str)
       Extractor for delimited strings. The left and right delimiters can be different.
