Functions

func Code

func Code(err error) codes.Code

Code returns the Code of the error if it is a RpcError error, codes.OK if err is nil, or codes.Unknown otherwise.

func Error

func Error(c codes.Code, msg string) error

Error returns an error representing c and msg. If c is OK, returns nil.

func ErrorWithCause

func ErrorWithCause(c codes.Code, cause error, msg string) error

Error returns an error with cause and msg.

func Errorf

func Errorf(c codes.Code, format string, a ...interface{}) error

Errorf returns Error(c, fmt.Sprintf(format, a...)).

func ErrorfWithCause

func ErrorfWithCause(c codes.Code, cause error, format string, a ...interface{}) error

Error returns an error with cause and formatted msg.

func ExtractErrCode

func ExtractErrCode(err error) (uint32, bool)

ExtractErrCode 从 error 消息中提取 uint32 的错误码

Types

type RpcError

type RpcError struct {
	Code    codes.Code `json:"code"`    // 错误码
