func Debugf Uses

❖
func Debugf(ctx context.Context, format string, args ...interface{})

Debugf logs a formatted string at the Debug level.

func Error Uses

❖
func Error(ctx context.Context, arg interface{})

Error logs arg, which can be a string or a struct, at the Error level.

func Errorf Uses

❖
func Errorf(ctx context.Context, format string, args ...interface{})

Errorf logs a formatted string at the Error level.

func Fatal Uses

❖
func Fatal(ctx context.Context, arg interface{})

Fatal is equivalent to Error followed by exiting the program.

func Fatalf Uses

❖
func Fatalf(ctx context.Context, format string, args ...interface{})

Fatalf is equivalent to Errorf followed by exiting the program.

func Info Uses

❖
func Info(ctx context.Context, arg interface{})

Info logs arg, which can be a string or a struct, at the Info level.

func Infof Uses

❖
func Infof(ctx context.Context, format string, args ...interface{})

Infof logs a formatted string at the Info level.

func NewContextWithLabel Uses

❖
func NewContextWithLabel(ctx context.Context, key, value string) context.Context

NewContextWithLabel creates anew context from ctx that adds a label that will appear in the log entry.

func NewContextWithTraceID Uses

❖
func NewContextWithTraceID(ctx context.Context, traceID string) context.Context

NewContextWithTraceID creates a new context from ctx that adds the trace ID.

func UseStackdriver Uses

❖
func UseStackdriver(ctx context.Context, cfg *config.Config, logName string) (_ *logging.Logger, err error)

UseStackdriver switches from the default stdlib logger to a Stackdriver logger. It assumes config.Init has been called. UseStackdriver returns a "parent" *logging.Logger that should be used to log the start and end of a request. It also creates and remembers internally a "child" logger that will be used to log within a request. The two loggers are necessary to get request-scoped logs in Stackdriver. See https://cloud.google.com/appengine/docs/standard/go/writing-application-logs.

UseStackdriver can only be called once. If it is called a second time, it returns an error.
