Constants

const (

	InfoLevel = iota
	// ErrorLevel includes errors, slows, stacks
	ErrorLevel
	// SevereLevel only log severe messages
	SevereLevel
)

Functions

func Close

func Close() error

func CollectSysLog

func CollectSysLog()

CollectSysLog redirects system log into logx info

func Disable

func Disable()

func Error

func Error(v ...interface{})

func ErrorCaller

func ErrorCaller(callDepth int, v ...interface{})

func ErrorCallerf

func ErrorCallerf(callDepth int, format string, v ...interface{})

func ErrorStack

func ErrorStack(v ...interface{})

func ErrorStackf

func ErrorStackf(format string, v ...interface{})

func Errorf

func Errorf(format string, v ...interface{})

func Info

func Info(v ...interface{})

func Infof

func Infof(format string, v ...interface{})

func Must

func Must(err error)

func MustSetup

func MustSetup(c LogConf)

func NewLessWriter

func NewLessWriter(writer io.Writer, milliseconds int) *lessWriter

func SetLevel

func SetLevel(level uint32)

func SetUp

func SetUp(c LogConf) error

SetUp sets up the logx. If already set up, just return nil. we allow SetUp to be called multiple times, because for example we need to allow different service frameworks to initialize logx respectively. the same logic for SetUp

func Severe

func Severe(v ...interface{})

func Severef

func Severef(format string, v ...interface{})

func Slow

func Slow(v ...interface{})

func Slowf

func Slowf(format string, v ...interface{})

func Stat

func Stat(v ...interface{})

func Statf

func Statf(format string, v ...interface{})
