Summary of Changes

Hello @merrymercy, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This automated pull request synchronizes changes to tokenizer_manager.py, primarily refactoring how ReqState objects are instantiated. By introducing self.req_state_class, the code now uses an instance attribute to create ReqState objects, which promotes better testability and flexibility in managing request states within the tokenizer.

Highlights

• ReqState Instantiation Refactor: The direct instantiation of ReqState has been replaced with self.req_state_class in tokenizer_manager.py, making the ReqState class accessible via an instance attribute.
• Improved Flexibility: This change likely enhances the flexibility and testability of the request state management by allowing for easier dependency injection or mocking of the ReqState class.

Code Review

This pull request refactors the TokenizerManager to use a configurable class attribute self.req_state_class for creating request state objects, instead of directly using the ReqState class. This is a good application of dependency injection, which improves the code's modularity, testability, and extensibility. The changes are implemented correctly and consistently. The code looks good, and I have no further recommendations.
