Types

type Formatter

type Formatter int

Formatter denotes a log formatter. Check the constants below for more information.

const (
	Text Formatter = iota
	TextWithoutTruncation
	JSON
)

func (Formatter) String

func (i Formatter) String() string

type Level

type Level int

Level denotes a log level. Check the constants below for more information.

const (
	Debug Level = iota
	Panic
)

func (Level) String

func (i Level) String() string

type Log

type Log struct {
	Level   string `json:"level,omitempty"`
	Message string `json:"msg,omitempty"`
	Time    string `json:"time,omitempty"`
}

Log defines the properties of every log message.

type Logger

type Logger interface {
	Debugf(format string, args ...interface{})
	Debugln(args ...interface{})
	Info(args ...interface{})
	Infof(format string, args ...interface{})
	Infoln(args ...interface{})
	Warnln(args ...interface{})
	Warnf(format string, args ...interface{})
	Error(args ...interface{})
	Errorf(format string, args ...interface{})
	Fatal(args ...interface{})
	SetLevel(level Level)
	SetFormatter(formatter Formatter)
}

Logger should be used to write any logs. No concrete implementations should be directly used.
