Types

type Level

type Level int32

Level represents a log level.

const (
	// FatalLevel is used for undesired and unexpected events that
	// the program cannot recover from.
	FatalLevel Level = iota

	// ErrorLevel is used for undesired and unexpected events that
	// the program can recover from.
	ErrorLevel

	// WarnLevel is used for undesired but relatively expected events,
	// which may indicate a problem.
	WarnLevel

	// InfoLevel is used for general informational log messages.
	InfoLevel

	// DebugLevel is the lowest level of logging.
	// Debug logs are intended for debugging and development purposes.
	DebugLevel
)

func ParseLevel

func ParseLevel(lvl string) (Level, error)

ParseLevel takes a string level and returns the Logrus log level constant.

func (Level) String

func (l Level) String() string

String is part of the fmt.Stringer interface.

Used for testing and debugging purposes.

func (Level) ToLogrusLevel

func (l Level) ToLogrusLevel() (logrus.Level, error)

type Logger

type Logger struct {
	// contains filtered or unexported fields
}

Logger logs message to io.Writer at various log levels.

func NewLogger

func NewLogger(out io.Writer) *Logger

NewLogger creates and returns a new instance of Logger. Log level is set to DebugLevel by default.

func (*Logger) Debug

func (l *Logger) Debug(args ...interface{})

func (*Logger) Debugf

func (l *Logger) Debugf(format string, args ...interface{})

func (*Logger) Error

func (l *Logger) Error(args ...interface{})

func (*Logger) Errorf

func (l *Logger) Errorf(format string, args ...interface{})

func (*Logger) Fatal

func (l *Logger) Fatal(args ...interface{})

func (*Logger) Fatalf

func (l *Logger) Fatalf(format string, args ...interface{})

func (*Logger) Info

func (l *Logger) Info(args ...interface{})

func (*Logger) Infof

func (l *Logger) Infof(format string, args ...interface{})

func (*Logger) SetLevel

func (l *Logger) SetLevel(v Level)

SetLevel sets the logger level. It panics if v is less than DebugLevel or greater than FatalLevel.

func (*Logger) SetPrefix

func (l *Logger) SetPrefix(value interface{})

WithField sets logger fields

func (*Logger) Warn

func (l *Logger) Warn(args ...interface{})

func (*Logger) Warnf

func (l *Logger) Warnf(format string, args ...interface{})

func (*Logger) WithError

func (l *Logger) WithError(err error) *logrus.Entry

func (*Logger) WithLogger

func (l *Logger) WithLogger() *logrus.Logger

type StdLogger

type StdLogger interface {
	Info(args ...interface{})
	Debug(args ...interface{})
	Warn(args ...interface{})
	Error(args ...interface{})
	Fatal(args ...interface{})

	Debugf(format string, args ...interface{})
	Infof(format string, args ...interface{})
	Warnf(format string, args ...interface{})
	Errorf(format string, args ...interface{})
	Fatalf(format string, args ...interface{})

	WithLogger() *logrus.Logger
	WithError(err error) *logrus.Entry
}
