Types

Name	Description
`basic_appender`
`basic_cstring_view`	A reference to a null-terminated string. It can be constructed from a C string or `std::string`.
`basic_format_arg`
`basic_format_args`	A view of a collection of formatting arguments. To avoid lifetime issues it should only be used as a parameter type in type-erased functions such as `vformat`:
`basic_fstring`
`basic_memory_buffer`	A dynamically growing memory buffer for trivially copyable/constructible types with the first `SIZE` elements stored in the object itself. Most commonly used via the `memory_buffer` alias for `char`.
`basic_ostream_formatter`
`basic_printf_context`
`basic_specs`
`basic_string_view`	An implementation of `std::basic_string_view` for pre-C++17. It provides a subset of the API. `fmt::basic_string_view` is used for format strings even if `std::basic_string_view` is available to prevent issues when a library is compiled with a different `-std` option than the client code (which is not recommended).

Functions

Name	Description
`Unnamed overloads`
`arg`	Returns a named argument to be used in a formatting function. It should only be used in a call to a formatting function.
`assert_fail`
`bg`	Creates a text style from the background color.
`fg`	Creates a text style from the foreground (text) color.
`format`	`format` overloads
`format_system_error`	Formats an error message for an error returned by an operating system or a language runtime, for example a file opening error, and writes it to `out`. The format is the same as the one used by `std::system_error(ec, message)` where `ec` is `std::error_code(error_code, std::generic_category())`. It is implementation-defined but normally looks like:
`format_to`	`format_to` overloads
`format_to_n`	Formats `args` according to specifications in `fmt`, writes up to `n` characters of the result to the output iterator `out` and returns the total (not truncated) output size and the iterator past the end of the output range. `format_to_n` does not append a terminating null character.
`formatted_size`	Returns the number of chars in the output of `format(fmt, args...)`.
`fprintf`	Formats `args` according to specifications in `fmt` and writes the output to `f`.
`gmtime`	Converts given time since epoch as `std::time_t` value into calendar time, expressed in Coordinated Universal Time (UTC). Unlike `std::gmtime`, this function is thread-safe on most platforms.
`group_digits`	Returns a view that formats an integer value using ',' as a locale-independent thousands separator.
`join`	`join` overloads
`make_format_args`
`make_printf_args`	Constructs an `format_arg_store` object that contains references to arguments and can be implicitly converted to `printf_args`.
`make_wformat_args`
`max_of`
`min_of`
`operator\|`	Bitwise disjunction operators
`print`	`print` overloads
`printf`	Formats `args` according to specifications in `fmt` and writes the output to `stdout`.
`println`	`println` overloads
`ptr`	Converts `p` to `const void*` for pointer formatting.
`report_error`	Reports a format error at compile time or, via a `format_error` exception, at runtime.
`report_system_error`
`runtime`	Creates a runtime format string.
`sprintf`	Formats `args` according to specifications in `fmt` and returns the result as as string.
`streamed`	Returns a view that formats `value` via an ostream `operator<<`.
`styled`	Returns an argument that will be formatted using ANSI escape sequences, to be used in a formatting function.
`system_category`
`system_error`	Constructs `std::system_error` with a message formatted with `fmt::format(fmt, args...)`. `error_code` is a system error code as given by `errno`.
`to_string`	Converts `value` to `std::string` using the default format for type `T`.
`to_wstring`	Converts `value` to `std::wstring` using the default format for type `T`.
`underlying`	Converts `e` to the underlying type.
`vformat`
`vformat_to`	`vformat_to` overloads
`vformat_to_n`
`vfprintf`
`vprint`
`vprint_buffered`
`vprintln`
`vsprintf`
`vsystem_error`
`operator==`	Equality operator
`operator!=`	Inequality operator
`operator<`	Less-than operator
`operator<=`	Less-than-or-equal operator
`operator>`	Greater-than operator
`operator>=`	Greater-than-or-equal operator
