func Annotate ¶

func Annotate(err error, msg string) error

Annotate prepends msg to the error message in err, attempting to preserve other information in err, like an error code.

Annotate panics if err is nil.

Annotate knows about these error types: - "google.golang.org/grpc/status".Status - "google.golang.org/api/googleapi".Error If the error is not one of these types, Annotate behaves like

fmt.Errorf("%s: %v", msg, err)

func Annotatef ¶

func Annotatef(err error, format string, args ...interface{}) error

Annotatef uses format and args to format a string, then calls Annotate.

It returns when one of the following occurs: When f's first return value is true, Retry immediately returns with f's second return value.
