-// Async logging using global thread pool
-// All loggers created here share same global thread pool.
-// Each log message is pushed to a queue along with a shared pointer to the
-// logger.
-// If a logger deleted while having pending messages in the queue, it's actual
-// destruction will defer
-// until all its messages are processed by the thread pool.
-// This is because each message in the queue holds a shared_ptr to the
-// originating logger.

- *
- * Since this is a branchless decoder, four bytes will be read from the
- * buffer regardless of the actual length of the next character. This
- * means the buffer _must_ have at least three bytes of zero padding
- * following the end of the data stream.
- *
- * Errors are reported in e, which will be non-zero if the parsed
- * character was somehow invalid: invalid byte sequence, non-canonical
- * encoding, or a surrogate half.
- *
- * The function returns a pointer to the next character. When an error
- * occurs, this pointer will be a guess that depends on the particular
- * error, but it will always advance at least one byte.

-  A dynamically growing memory buffer for trivially copyable/constructible types

-
-  You can use one of the following type aliases for common character types:
-
-  +----------------+------------------------------+
-  | Type           | Definition                   |
-  +================+==============================+
-  | memory_buffer  | basic_memory_buffer<char>    |
-  +----------------+------------------------------+
-  | wmemory_buffer | basic_memory_buffer<wchar_t> |
-  +----------------+------------------------------+
-
-  **Example**::
-
-     fmt::memory_buffer out;
-     format_to(out, "The answer is {}.", 42);
-
-  This will append the following output to the ``out`` object:
-
-  .. code-block:: none
-
-     The answer is 42.
-
-  The output can be converted to an ``std::string`` with ``to_string(out)``.

-// Thread safe logger (except for set_error_handler())
-// Has name, log level, vector of std::shared sink pointers and formatter
-// Upon each log write the logger:
-// 1. Checks if its log level is enough to log the message and if yes:
-// 2. Call the underlying sinks to do the job.
-// 3. Each sink use its own private copy of a formatter to format the message
-// and send to its destination.
-//
-// The use of private formatter per sink provides the opportunity to cache some
-// formatted data, and support for different format per sink.

-// Writing to Windows Event Log requires the registry entries below to be present, with the following modifications:
-// 1. <log_name>    should be replaced with your log name (e.g. your application name)
-// 2. <source_name> should be replaced with the specific source name and the key should be duplicated for
-//                  each source used in the application
-//
-// Since typically modifications of this kind require elevation, it's better to do it as a part of setup procedure.
-// The snippet below uses mscoree.dll as the message file as it exists on most of the Windows systems anyway and
-// happens to contain the needed resource.
-//
-// You can also specify a custom message file if needed.
-// Please refer to Event Log functions descriptions in MSDN for more details on custom message files.
