Adds the skip_formatter attribute to an object so that logger will skip calling the formatter function(s). This is useful if you want to preprocess the log message with a custom function instead of the active formatter function(s). Note that the message should be a string, and skip_formatter should be the only input for the logging function to make this work.
skip_formatter(message, ...)character vector directly passed to the appender function in logger
should be never set
character vector with skip_formatter attribute set to TRUE
