Types

type LogLevel

type LogLevel string

const (
	TRACE LogLevel = LogLevel("TRACE")
	DEBUG LogLevel = LogLevel("DEBUG")
	INFO  LogLevel = LogLevel("INFO")
	WARN  LogLevel = LogLevel("WARN")
	ERROR LogLevel = LogLevel("ERROR")
	FATAL LogLevel = LogLevel("FATAL")
)

func LogLevelFromString

func LogLevelFromString(level string) LogLevel

func VerbosityLevelFromString

func VerbosityLevelFromString(verbosity string) LogLevel

func (LogLevel) String

func (l LogLevel) String() string

type LogLevelValue

type LogLevelValue int

type LogRotator

type LogRotator interface {
	IsEnabled() bool
	Hook(msgLen int64) rerrors.Error
	GetDefaultWriter() (io.Writer, bool)
	UpdateCallBack(callback RotationCallBack)
}

func NewLogNoRotator

func NewLogNoRotator(folder *os.File, fileName string, callback RotationCallBack) (LogRotator, error)

func NewLogRotator

func NewLogRotator(folder *os.File, fileName string, maxFileSize int64, maxNoFiles int, callback RotationCallBack) (LogRotator, error)

Returns NEw LogRotator, in case dile size or number of rotations is less or equals to 0 no rotation will be prformed, and the file will increase size, continuously. Please take care to this topic
