Types ¶

type DefaultLogger ¶

type DefaultLogger struct {
}

DefaultLogger is enabled when no consuming clients provide a logger to the server/cache subsystem

func NewDefaultLogger ¶

func NewDefaultLogger() *DefaultLogger

NewDefaultLogger creates a DefaultLogger which is a no-op to maintain current functionality

func (*DefaultLogger) Debugf ¶

func (l *DefaultLogger) Debugf(string, ...interface{})

Debugf logs a message at level debug on the standard logger.

func (*DefaultLogger) Errorf ¶

func (l *DefaultLogger) Errorf(string, ...interface{})

Errorf logs a message at level error on the standard logger.

func (*DefaultLogger) Infof ¶

func (l *DefaultLogger) Infof(string, ...interface{})

Infof logs a message at level info on the standard logger.

func (*DefaultLogger) Warnf ¶

func (l *DefaultLogger) Warnf(string, ...interface{})

Warnf logs a message at level warn on the standard logger.

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.

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

Infof logs a formatted informational message.

func (LoggerFuncs) Warnf ¶

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

Warnf logs a formatted warning message.
