func (LabelField) Set 

func (l LabelField) Set(entry *Entry, val interface{}) error

Set will set the label value on an entry

func (LabelField) String 

func (l LabelField) String() string

type NilField 

type NilField struct{}

NilField is a struct that implements Field, but does nothing for all its operations. It is useful as a default no-op field to avoid nil checks.

func (NilField) Delete 

func (l NilField) Delete(entry *Entry) (interface{}, bool)

Delete will do nothing and return no error

func (NilField) Get 

func (l NilField) Get(entry *Entry) (interface{}, bool)

Get will return always return nil

func (NilField) Set 

func (l NilField) Set(entry *Entry, val interface{}) error

Set will do nothing and return no error
