Formatters

Formatters convert a LogMessage into a string that sinks can deliver. Every formatter implements IMessageFormatter:

public interface IMessageFormatter
{
    string Format(LogMessage logMessage);
}

Where formatters are used

• Logger.Formatter -> global default formatter (used when no per-sink formatter is set)
• Sink.Formatter -> per-sink override (all sinks support this: FileLogSink, ConsoleLogSink, UnityLogSink, and CloudLogSink subclasses)

// Set the global default
Log.Container.Logger.Formatter = new JsonFormatter();

// Override for a specific sink
myDiscordSink.Formatter = new DiscordFormatter();
myFileSink.Formatter = new JsonFormatter();
