Types

type BaseLogger

type BaseLogger interface {
	Printf(format string, v ...interface{})
	Println(v ...interface{})
	Debugf(format string, v ...interface{})
	Debug(v ...interface{})
	Infof(format string, v ...interface{})
	Info(v ...interface{})
	Warnf(format string, v ...interface{})
	Warn(v ...interface{})
	Errorf(format string, v ...interface{})
	Error(v ...interface{})
	Fatalf(format string, v ...interface{})
	Fatal(v ...interface{})
	Panicf(format string, v ...interface{})
	Panic(v ...interface{})
}

BaseLogger defines interface of application log apis.

type Level

type Level int

Level type log level

const (
	Ldebug Level = iota
	Linfo
	Lwarn
	Lerror
	Lpanic
	Lfatal
)

defines log level

func GetOutputLevel

func GetOutputLevel() Level

func (*Level) UnmarshalJSON

func (l *Level) UnmarshalJSON(data []byte) error

UnmarshalJSON unserialize log level with json. Try compatible digit firstly then string.

func (*Level) UnmarshalYAML

func (l *Level) UnmarshalYAML(unmarshal func(interface{}) error) error

UnmarshalYAML unserialize log level with yaml.

type Logger

type Logger interface {
	BaseLogger

	// atomically control log level
	GetOutputLevel() Level
	SetOutputLevel(logLevel Level)
	SetOutput(w io.Writer)
	Output(id string, lvl Level, calldepth int, s string) error

	// implement raft Logger with these two function
	Warningf(format string, v ...interface{})
	Warning(v ...interface{})
}

Logger a implemented logger should implements all these function.

var DefaultLogger Logger

DefaultLogger default logger initial with os.Stderr.

func New

func New(out io.Writer, calldepth int) Logger

New return a logger with default level Linfo. output buffer with reused bytes pool.
