Functions

func FromStatusError

func FromStatusError(maybeStatusErr error) (err error)

FromStatusError converts an grpc/status.statusError into an error. There are below cases: - If maybeStatusErr is nil, it returns nil. - If maybeStatusErr is not type of grpc/status.statusError, it returns maybeStatusErr again. - In case of that maybeStatusErr is type of grpc/status.statusError:

• try to parse Details field, and return an error if it is parsed
• if the error is not parsed, and its code is either grpc/codes.DeadlineExceeded or grpc/codes.Canceled, FromStatusError returns context error
• if the code is code.Unavailable, then wrap the error by transientError and return it

func IsTransient

func IsTransient(err error) bool

IsTransient checks if err is temporarily error.

func ToErr

func ToErr(ctx context.Context, err error) error

func ToStatusError

func ToStatusError(err error) error

ToStatusError converts an errors into grpc/status.statusError. It usually is used before sending responses via gRPC. If the err is either context.DeadlineExceeded or context.Canceled, it returns grpc/status.statusError having a code of either codes.DeadlineExceeded or codes.Canceled.

func ToStatusErrorWithCode

func ToStatusErrorWithCode(err error, code codes.Code) error
