| template< ranges::input_range R, class CharT > struct range-default-formatter<range_format::sequence, R, CharT>; |
(since C++23) (exposition only*) |
|
The class template range-default-formatter for range types is specialized 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 |
underlying_ (private)
|
the underlying formatter of type: std::range_formatter<std::remove_cvref_t< ranges::range_reference_t<maybe-const-r>>, CharT>(exposition-only member object*) |
Member functions
| (constructor) (implicitly declared) |
constructs a range-default-formatter (public member function) |
| set_separator |
sets a specified separator for the range formatted result (public member function) |
| set_brackets |
sets a specified opening and closing brackets for the range formatted result (public member function) |
| parse |
parses the format specifier as specified by range-format-spec (public member function) |
| format |
writes the range formatted output as specified by 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 ) noexcept; |
||
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.
