	InfoLevel  Level = 2 // Informational messages
)

func ParseLevel

type Logger

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

func NewFileLogger

func NewLogger

func NewLogger(out io.WriteCloser, logLevel Level) Logger

func (Logger) Close

func (l Logger) Close() error

func (Logger) Error
