Function encodePkgFundamental

errbase/adapters.go:51–58

errors.fundamental from github.com/pkg/errors cannot be encoded exactly because it includes a non-serializable stack trace object. In order to work with it, we encode it by dumping the stack trace in a safe reporting detail field, and decode it as an opaqueLeaf instance in this package.

(
	_ context.Context, err error,
)

// it as an opaqueLeaf instance in this package.

func encodePkgFundamental(
	_ context.Context, err error,
) (msg string, safe []string, _ proto.Message) {
	msg = err.Error()
	iErr := err.(interface{ StackTrace() pkgErr.StackTrace })
	safeDetails := []string{fmt.Sprintf("%+v", iErr.StackTrace())}
	return msg, safeDetails, nil
}

// errors.withMessage from github.com/pkg/errors can be encoded
// exactly because it just has a message prefix. The base encoding
