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.

Example

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
