type Level int

const (
	TRACE Level = iota
	DEBUG
	INFO
	WARN
	ERROR
	FATAL
	BOUNDARY
)

type Logger ¶

type Logger interface {
	// The following are printers that print at or below the given level from the constants above
	Fatal(txt ...interface{})
	Error(txt ...interface{})
	Warn(txt ...interface{})
	Info(txt ...interface{})
	Debug(txt ...interface{})
	Trace(txt ...interface{})
	Fatalf(format string, txt ...interface{})
	Errorf(format string, txt ...interface{})
	Warnf(format string, txt ...interface{})
	Infof(format string, txt ...interface{})
	Debugf(format string, txt ...interface{})
	Tracef(format string, txt ...interface{})
	Errors(txt interface{})
	Warns(txt interface{})
	Infos(txt interface{})
	Debugs(txt interface{})
	Traces(txt interface{})
	Fatalc(fn func() string)
	Errorc(fn func() string)
	Warnc(fn func() string)
	Infoc(fn func() string)
	Debugc(fn func() string)
	Tracec(fn func() string)
	// Check prints at error level if the error was not nil and returns true
	Check(err error) bool
	// SetPrinter enables loading a printer function to enable networked, piped, etc outputs
	SetPrinter(fn Printer)
	// SetLevel sets the error level, anything lower will not call the printer function
	SetLevel(level Level)
}

Logger is an interface that defines the set of operations relevant to a logger.
