Exercise: Tokenize Server Streaming RPC

Tokenize text RPC

In this exercise, your goal is to implement a tokenize RPC Server Streaming API in a TextEditorService.

• The function takes a TokenizeRequest message that contains a string and a delimiter.

• It returns a stream of Result messages where each message represents a tokenized part of the original string.

Follow these steps:

1. Define the RPC in a .proto file: Define the RPC in the service definition in the proto file.

2. Implement the server code: Implement the server logic to handle the request and return the tokenized response.

3. Test the server code by implementing the client: Ensure the client can send a string and delimiter, and the server responds with a stream of tokenized strings.

The client will send the string “hello world from gRPC!” with a space token, and the server will respond with a stream of “hello”, “world”, “from”, and “gRPC!”. ...
