Implementing RPC services

The gRPC framework leverages the stream multiplexing capabilities of HTTP/2 so that it can handle both synchronous and asynchronous RPCs. The protoc compiler, when invoked with the grpc plugin enabled, will generate the following:

• Client and server interfaces for every RPC service definition in the compiled .proto file. For a service named Foo, the compiler will generate a FooServer and a FooClient interface. This is quite a useful feature as it allows us to inject mocked clients into our code at test time.
• Complete client implementation for each service that adheres to the generated client interface.
• A helper function to register our service implementation with a gRPC server instance. Once again, for a service ...
