impl Greeter for GreeterService {
    async fn say_hello(
        &self,
        request: Request<HelloRequest>,
    ) -> Result<Response<HelloReply>, Status> {
        let reply = HelloReply {
            message: format!("Hello {}!", request.into_inner().name),
        };
        Ok(Response::new(reply))
    }
}

#[tokio::main]
async fn main() -> Result<(), std::io::Error> {
    let route = RouteGrpc::new().add_service(GreeterServer::new(GreeterService));
    Server::new(TcpListener::bind("127.0.0.1:3000"))
        .run(route)
