	Error LogLevel = "errors"
	// Fatal is for logging fatal messages. The system shutdown after logging the message.
	Fatal LogLevel = "fatal"
)

type Logger

type Logger interface {
	Debugf(format string, args ...interface{})

	Infof(format string, args ...interface{})

	Errorf(format string, args ...interface{})

	Fatalf(format string, args ...interface{})

	WithFields(keyValues Fields) Logger
}

Logger is our contract for the logger.
