Variables

var NullLogger = &nullLogger{}

NullLogger is implementation of the Logger interface that is no-op

var StdLogger = &stdLogger{}

StdLogger is implementation of the Logger interface that delegates to default `log` package

Types

type BytesBufferLogger

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

BytesBufferLogger implements Logger backed by a bytes.Buffer.

func (*BytesBufferLogger) Debugf

func (l *BytesBufferLogger) Debugf(msg string, args ...interface{})

Debugf implements Logger.

func (*BytesBufferLogger) Error

func (l *BytesBufferLogger) Error(msg string)

Error implements Logger.

func (*BytesBufferLogger) Flush

func (l *BytesBufferLogger) Flush()

Flush empties the underlying buffer.

func (*BytesBufferLogger) Infof

func (l *BytesBufferLogger) Infof(msg string, args ...interface{})

Infof implements Logger.

func (*BytesBufferLogger) String

func (l *BytesBufferLogger) String() string

String returns string representation of the underlying buffer.

type DebugLogger

type DebugLogger interface {
	Logger

	// Debugf logs a message at debug priority
	Debugf(msg string, args ...interface{})
}

DebugLogger is an interface which adds a debug logging level

func DebugLogAdapter

func DebugLogAdapter(logger Logger) DebugLogger

DebugLogAdapter is a log adapter that converts a Logger into a DebugLogger If the provided Logger doesn't satisfy the interface, a logger with debug disabled is returned

type Logger

type Logger interface {
	// Error logs a message at error priority
	Error(msg string)

	// Infof logs a message at info priority
	Infof(msg string, args ...interface{})
}

Logger provides an abstract interface for logging from Reporters. Applications can provide their own implementation of this interface to adapt reporters logging to whatever logging library they prefer (stdlib log, logrus, go-logging, etc).
