Types

type Level

type Level int

Level describes the chosen log level

const (
	LevelDebug Level = iota
	LevelInfo
	LevelWarn
	LevelError
	LevelCritical
	LevelFatal
	LevelNone

	DefaultLogThreshold    = LevelInfo
	DefaultStdoutThreshold = LevelInfo
)

type NotePad

type NotePad struct {
	Handle io.Writer
	Level  Level
	Prefix string
	Logger **log.Logger
}
