Hello!

I am currently working on "D Language Client Libraries for Google 
APIs" project[0][1].
The first step was to familiarize myself with protobuf and to 
generate client library for cloud/vision using python plugin with 
protoc.
Today I generated the same library with protobuf-d[2]. When I 
tried to translate this example[3] from python to D, I noticed 
that some pieces of code are missing from the D generated 
library, for example the ImageAnnotatorClient class(or struct) (I 
could not found it anywhere in the generated code).

Here is the command that I used to generate the client library:

protoc path/to/cloud/vision/proto/files
--proto_path=path/to/common/api/protos --proto-path=.
--plugin=path/to/protobuf-d --d_opt=message-as-struct
--d_out=path/to/output/files

Is that ok? Does it work as it should?
Also I read here[4] that the C++ generator defines some default 
methods.
Wasn't the proto-gen-d supposed to do the same?

Thanks!

ImageAnnotatorClient isn't described in any of *.proto file in 
https://github.com/googleapis/googleapis repository. (I found 
only ImageAnnotator)

So, maybe here is messed up proto3 and gRPC or something like it?
