std::range-...t-formatter(3) C++ Standard Libary std::range-...t-formatter(3) NAME std::range-default-formatter - std::range-default-formatter Synopsis Defined in header <format> template< ranges::input_range R, class CharT > (since C++23) struct range-default-formatter<range_format::sequence, R, (expo- sition only*) CharT>; The class template range-default-formatter for range types is special- ized for formatting range as a sequence of elements if std::format_kind<R> is std::range_format::sequence. Member types Member type Definition maybe-const-r (private) /*fmt-maybe-const*/<R, CharT> (exposition-only member type*) Member objects Member name Definition the underlying formatter of type underlying_ std::range_format- ter<std::remove_cvref_t<ranges::range_reference_t<maybe-const-r>>, (pri- vate) CharT> (exposition-only member object*) Member functions constructor constructs a range-default-formatter (implicitly declared) (public member function) set_separator sets a specified separator for the range formatted result (public member function) sets a specified opening and closing brackets for the range set_brackets formatted result (public member function) parse parses the format specifier as specified by range- format-spec (public member function) writes the range formatted output as specified by format range-format-spec (public member function) std::range-default-formatter<std::range_format::sequence>::set_separator constexpr void set_separator( std::basic_string_view<CharT> sep ) noex- cept; Equivalent to a call to underlying_.set_separator(sep). std::range-default-formatter<std::range_format::sequence>::set_brackets constexpr void set_brackets( std::basic_string_view<CharT> opening, std::basic_string_view<CharT> closing ) noexcept; Equivalent to a call to underlying_.set_brackets(opening, closing). std::range-default-formatter<std::range_format::sequence>::parse template< class ParseContext > constexpr auto parse( ParseContext& ctx ) -> ParseContext::iterator; Equivalent to return underlying_.parse(ctx);. Returns an iterator past the end of the range-format-spec. std::range-default-formatter<std::range_format::sequence>::format template< class FormatContext > auto format( maybe-const-r& elems, FormatContext& ctx ) const -> FormatContext::iterator; Equivalent to return underlying_.format(elems, ctx);. Returns an iterator past the end of the output range.
