std::formatter<std::queue>
From cppreference.com
| 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) | |
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.

[edit] Member functions
| 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::formatter<std::queue>::parse
| template< class ParseContext > 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.
