type Loggers 

type Loggers interface {
	io.Closer
	// Check returns whether the loggers are correctly defined or not.
	Check() error
	// SetLogSource sets the source of the log message e.g. related build job, related command, etc.
	SetLogSource(source string) error
	// SetLoggerSource sets the source of the logger e.g. APIs, Build worker, CMSIS tools.
	SetLoggerSource(source string) error
	// Log logs to the output stream/logger.
	Log(output ...interface{})
	// LogError logs to the Error stream/logger.
	LogError(err ...interface{})
}

Loggers defines generic loggers which separate common logging messages from errors. This is to use in cases where it is necessary to separate the two streams e.g. remote procedure call (RPC) In most cases however, if only a standard logger is needed, it is advised to use logr.Logger.
