Types ¶

type LogHandler ¶

type LogHandler struct {
	// contains filtered or unexported fields
}

func (*LogHandler) HandleLog ¶

func (h *LogHandler) HandleLog(e *alog.Entry) error

type Logger ¶

type Logger interface {
	Debug(arg string)
	Debugf(format string, args ...interface{})
	Info(arg string)
	Infof(format string, args ...interface{})
	Warn(arg string)
	Warnf(format string, args ...interface{})
	Error(arg string)
	Errorf(format string, args ...interface{})

	// Log and terminate process (unrecoverable)
	Fatal(arg string)

	// Log with fmt.Printf-like formatting and terminate process (unrecoverable)
	Fatalf(format string, args ...interface{})

	// Set key/value context for further logging with the returned logger
	WithField(key string, value interface{}) *alog.Entry

	// Set key/value context for further logging with the returned logger
	WithFields(keyValues alog.Fielder) *alog.Entry

	// Return a logger with the specified error set, to be included in a subsequent normal logging call
	WithError(err error) *alog.Entry
}
