The template specialization ofstd::formatter for the range types allows users to convert a range to its textual representation as a collection of elements or a string usingformatting functions.
The specialization is derived fromrange-default-formatter<std::format_kind<R>, R, CharT>.
The specialization is enabled ifR satisfiesinput_range,std::format_kind<R> is notstd::range_format::disabled, andstd::formattable<ranges::range_reference_t<R>, CharT> istrue.
This specialization meets theFormatter requirements ifconst R modelsinput_range andranges::range_reference_t<const R> modelsstd::formattable<CharT>. It always meets theBasicFormatter requirements.

The syntax ofrange-format-spec is:
range-fill-and-align (optional)width (optional)n(optional)range-type (optional)range-underlying-spec (optional) | |||||||||
The syntax is fully described inrange format specification.
For specializations ofstd::formatter wherestd::format_kind<R> is eitherstd::range_format::string orstd::range_format::debug_string, theformat-spec isstd-format-spec instead ofrange-format-spec (which usesstd::formatter<std::basic_string<CharT>, CharT> as the underlying formatter).
