Package status

import ""

Overview ▾

Package status implements errors returned by gRPC. These errors are serialized and transmitted on the wire between server and client, and allow for additional data to be transmitted via the Details field in the status proto. gRPC service handlers should return an error created by this package, and gRPC clients should expect a corresponding error to be returned from the RPC call.

This package upholds the invariants that a non-nil error may not contain an OK code, and an OK code must result in a nil error.

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 ErrorProto

func ErrorProto(s *spb.Status) error

ErrorProto returns an error representing s. If s.Code is OK, returns nil.

func Errorf

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

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

type Status

Status represents an RPC status code, message, and details. It is immutable and should be created with New, Newf, or FromProto.

type Status struct {
    // contains filtered or unexported fields

func FromError

func FromError(err error) (s *Status, ok bool)

FromError returns a Status representing err if it was produced from this package, otherwise it returns nil, false.

func FromProto

func FromProto(s *spb.Status) *Status

FromProto returns a Status representing s.

func New

func New(c codes.Code, msg string) *Status

New returns a Status representing c and msg.

func Newf

func Newf(c codes.Code, format string, a ...interface{}) *Status

Newf returns New(c, fmt.Sprintf(format, a...)).

func (*Status) Code

func (s *Status) Code() codes.Code

Code returns the status code contained in s.

func (*Status) Err

func (s *Status) Err() error

Err returns an immutable error representing s; returns nil if s.Code() is OK.

func (*Status) Message

func (s *Status) Message() string

Message returns the message contained in s.

func (*Status) Proto

func (s *Status) Proto() *spb.Status

Proto returns s's status as an spb.Status proto message.
