1# Status 2 3This is a convenience package for users of `gogo/protobuf` to be able to use 4their `gogo/protobuf` generated message easily and transparently with the 5gRPC status error structure. 6 7It requires [Go gRPC version 1.11](https://github.com/grpc/grpc-go/releases/tag/v1.11.0) 8or above to successfully transmit statuses over the gRPC transport. 9 10## Use 11 12Use as you would the normal `grpc/status` package: 13 14```go 15return status.Error(codes.NotFound, "no such user") 16``` 17 18```go 19st := status.New(codes.FailedPrecondition, "wrong user role") 20detSt, err := st.WithDetails(&rpc.BadRequest{ 21 FieldViolations: []*rpc.BadRequest_FieldViolation{ 22 { 23 Field: "role", 24 Description: "The first user created must have the role of an ADMIN", 25 }, 26 }, 27}) 28if err == nil { 29 return detSt.Err() 30} 31return st.Err() 32``` 33 34## License 35 36The code is 95% copied from the official gRPC status package, so the gRPC 37License applies. 38 39### Changes 40 41The changes applied include changing the use of the 42`golang/protobuf` packages to `gogo/protobuf`, and changing the 43generated files from `google.golang.org/genproto/googleapis` to 44`github.com/gogo/googleapis/`. 45 46We've also created an implicit interface fulfilled by all `gogo/status` 47errors, for use with `grpc/status` and the gRPC runtime libraries. 48
