Tables
std::queue Defined in header
<queue>
template< class CharT, class T, std::formattable <CharT> Container, class... U >
struct formatter<std::queue <T, Container, U...>, CharT>;
(since C++23)
struct formatter<std::queue <T, Container, U...>, CharT>;
The template specialization of std::formatter for the container adaptor type std::queue allows users to convert the underlying container to its textual representation as a collection of elements using formatting functions.
The specialization is enabled if std::formattable <Container, CharT> is true.

format
(public member function)
std::formatter<std::queue>::parse
template< class ParseContext >
constexpr auto parse( ParseContext& ctx ) -> ParseContext::iterator;
constexpr auto parse( ParseContext& ctx ) -> ParseContext::iterator;
Equivalent to return underlying_ .parse(ctx);.
Return value
An iterator past the end of the range-format-spec of the underlying container.
std::formatter<std::queue>::format
template< class FormatContext >
auto format( /*maybe-const-adaptor*/& r, FormatContext& ctx ) const
Equivalent to return underlying_ .format(r.c, ctx);.
Return value
An iterator past the end of the output range.
