func (entry *LogEntry) ToText() []byte

ToJSON returns the text line formatted entry as byte array

type LogFormat 

type LogFormat byte

LogFormat defines the format of the log that will be processed by a handler 

const (
	// TextFormat represents that the hadler will accept the log entry in text line format as input
	TextFormat LogFormat = iota
	// JSONFormat represents that the hadler will accept the log entry in JSON format as input
	JSONFormat
	// CustomFormat represents that the hadler will accept the log entry as input and will format the entry by it self
	CustomFormat
)

type LogHandler 

type LogHandler interface {
	// Name returns the name of the handler used for registration
