func (s *server) StreamStockPrices(req *stockRequest, stream stockpb.StockService_StreamStockPricesServer) error { // simulate streaming stock prices for i := 0; i < 10; i++ { stockPrice := &stockpb.StockPrice{ Ticker: req.GetTicker(), Price: float32(rand.Int31n(1000)), } stream.Send(stockPrice) time.Sleep(time.Second) } return nil }In this example, `StreamStockPrices` is a gRPC server-side function that accepts a `stockRequest` and a `stockpb.StockService_StreamStockPricesServer` object. The function loops through 10 iterations, sending a randomly generated `stockPrice` to the client through the `stream` object. The `time.Sleep` call is used to simulate the streaming of real-time data. Overall, the gRPC package library in Go provides a convenient way to stream data through ServerStream to clients, making it easy to send large amounts of data or continuous updates.
