type LoggableObject 

type LoggableObject interface {

type LogrusWrapper 

type LogrusWrapper struct {
	Log *LogObject
}

LogrusWrapper wraps LogObject to implement the same interface as the widely used Sirupsen/Logrus (see https://github.com/sirupsen/logrus) This may allow to use LogObject in libraries outside of pillar. However, only methods with formatted output are wrapped for now.

func (*LogrusWrapper) Debugf 

func (w *LogrusWrapper) Debugf(format string, args ...interface{})

Debugf : formatted log message with info useful for debugging.

func (*LogrusWrapper) Errorf 

func (w *LogrusWrapper) Errorf(format string, args ...interface{})

Errorf : formatted log message with an error.

func (*LogrusWrapper) Fatalf 

func (w *LogrusWrapper) Fatalf(format string, args ...interface{})

Fatalf : formatted log message with an error, ending with a call to os.Exit() with a non-zero return value.

func (*LogrusWrapper) Infof 

func (w *LogrusWrapper) Infof(format string, args ...interface{})

Infof : formatted log message with a general info about what's going on inside the application.

func (*LogrusWrapper) Panicf 

func (w *LogrusWrapper) Panicf(format string, args ...interface{})

Panicf : formatted log message with an error, raising a panic.

func (*LogrusWrapper) Tracef 

func (w *LogrusWrapper) Tracef(format string, args ...interface{})

Tracef : formatted log message with info useful for finer-grained debugging.

func (*LogrusWrapper) Warningf 

func (w *LogrusWrapper) Warningf(format string, args ...interface{})

Warningf : formatted log message with a warning.

type RelationObjectType 

type RelationObjectType string

RelationObjectType : 

const (
	// UnknownRelationType : Invalid relation type
	UnknownRelationType RelationObjectType = ""
	// AddRelationType :
	AddRelationType RelationObjectType = "add_relation"
	// DeleteRelationType :
