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.
Code returns the Code of the error if it is a Status error, codes.OK if err is nil, or codes.Unknown otherwise.
Error returns an error representing c and msg. If c is OK, returns nil.
ErrorProto returns an error representing s. If s.Code is OK, returns nil.
Errorf returns Error(c, fmt.Sprintf(format, a...)).
type Status struct {
// contains filtered or unexported fields
}
Status represents an RPC status code, message, and details. It is immutable and should be created with New, Newf, or FromProto.
Convert is a convenience function which removes the need to handle the boolean return value from FromError.
FromError returns a Status representing err if it was produced from this package or the standard grpc/status package. Otherwise, ok is false and a Status is returned with codes.Unknown and the original error message.
FromGRPCStatus converts a grpc.Status to gogo.Status.
FromProto returns a Status representing s. nolint: interfacer
New returns a Status representing c and msg.
Newf returns New(c, fmt.Sprintf(format, a...)).
Code returns the status code contained in s.
Details returns a slice of details messages attached to the status. If a detail cannot be decoded, the error is returned in place of the detail.
Err returns an immutable error representing s; returns nil if s.Code() is OK.
Message returns the message contained in s.
Proto returns s's status as an rpc.Status proto message.
WithDetails returns a new status with the provided details messages appended to the status. If any errors are encountered, it returns nil and the first error encountered.
