Types ¶

type Logger ¶

type Logger interface {
	// Debugf logs a formatted debugging message.
	Debugf(format string, args ...interface{})

	// Infof logs a formatted informational message.
	Infof(format string, args ...interface{})

	// Warnf logs a formatted warning message.
	Warnf(format string, args ...interface{})

	// Errorf logs a formatted error message.
	Errorf(format string, args ...interface{})
}

Logger interface for reporting informational and warning messages.

type LoggerFuncs ¶

type LoggerFuncs struct {
	DebugFunc func(string, ...interface{})
	InfoFunc  func(string, ...interface{})
	WarnFunc  func(string, ...interface{})
	ErrorFunc func(string, ...interface{})
}

LoggerFuncs implements the Logger interface, allowing the caller to specify only the logging functions that are desired.

{
	logger := log.Logger{}

	xdsLogger := LoggerFuncs{
		DebugFunc: logger.Printf,
		InfoFunc:  logger.Printf,
		WarnFunc:  logger.Printf,
		ErrorFunc: logger.Printf,
	}

	xdsLogger.Debugf("debug")
	xdsLogger.Infof("info")
	xdsLogger.Warnf("warn")
	xdsLogger.Errorf("error")
}

func (LoggerFuncs) Debugf ¶

func (f LoggerFuncs) Debugf(format string, args ...interface{})

Debugf logs a formatted debugging message.

func (LoggerFuncs) Errorf ¶

func (f LoggerFuncs) Errorf(format string, args ...interface{})

Errorf logs a formatted error message.

func (LoggerFuncs) Infof ¶

func (f LoggerFuncs) Infof(format string, args ...interface{})
