Description
This example demonstrates basic RPC error handling in gRPC.
Run the sample code
Run the server, which returns an error if the RPC request's Name field is
empty.
$ go run ./server/main.go
Then run the client in another terminal, which does two requests: one with an empty Name field and one with it populated with the current username provided by os/user.
$ go run ./client/main.go
It should print the status codes it received from the server.
