[Brian]

Google gRPC is A high performance, open-source universal RPC 
framework.

You can find it here:
https://grpc.io/

hunt-grpc is a GRPC framework developed in D language. The new 
version mainly supports two-way communication and fixes some 
known errors.

Example for server:
```D
   import helloworld.helloworld;
   import helloworld.helloworldrpc;
   import grpc;

   class GreeterImpl : GreeterBase
   {
       override Status SayHello(HelloRequest request , ref 
HelloReply reply)
       {
           reply.message = "hello " ~ request.name;
           return Status.OK;
       }
   }

   string host = "0.0.0.0";
   ushort port = 50051;

   Server server = new Server();
   server.listen(host , port);
   server.register( new GreeterImpl());
   server.start();
```

Example for client:
```D
   import helloworld.helloworld;
   import helloworld.helloworldrpc;
   import grpc;
   import std.stdio;

   auto channel = new Channel("127.0.0.1" , 50051);
   GreeterClient client = new GreeterClient(channel);

   HelloRequest request = new HelloRequest();
   HelloReply reply = new HelloReply();
   request.name = "test";
   auto status = client.SayHello(request , reply);
   if(status.ok())
   {
      writeln(reply.message);
   }
```
