Best Way to Adjust the String Dynamically

[aurexav]

It appears that it's not possible to modify the SharedString. I'm seeking a similar concept to VecModel, but specifically for strings.

I'm developing an OpenAI-based chatting tool that accepts HTTP SSE responses. To enhance the user experience, I intend to append each new word as it arrives. However, I've discovered that I can't modify the SharedString in the same manner as I can with Rc<ModelVec>. Consequently, I'm forced to reset the entire string every time.
