Starlette RAS-handler

This library adds the ability to handle RuntimeError: Caught handled exception, but response already started. error, so you can silent it, or do whatever you want

Usage

1. Define an async function that accepts (Exception, Request | WebSocket) and returns None

   async def print_handler(exc: Exception, request: Request | WebSocket) -> None:
       print("Caught", exc)
   

2. Patch!

   from handler import print_handler
   
   from starlette_ras_handle import handle_starlette_ras
   handle_starlette_ras(print_handler)
   
   # other imports...
   

IMPORTANT: If you want the patch to work properly, you should use it before you import anything, related to starlette (e.g. FastAPI)
