Rising Responses about starlette HOT 5 CLOSED

I think it’s probably better for the library to have handled exceptions be more constrained then simply general purpose responses. That makes it easier to modify the error handling.

I don't mean using it for exceptions on the library level. It just convenient when you can just "raise" response from some nested coroutine or a middleware rather than passing it all the way back.

Sure, and we have HTTPException for that kind of use-case. It’s just more constrained than having Response itself be an exception class.

Looking at the code and don't see how can I use a particular response (let's say RedirectResponse) with HTTPException? Let me clarity what I mean by example, with this rising feature we can write:

@app.route('/')
def homepage(request):
    validate_request(request):
    return JSONResponse({'hello': 'world'})

def validate(request):
    raise JSONResponse({...}, status_code=400)

I guess you could make this work by using a mixin / custom JSONResponse class, and handling it via @app.exception_handler(RaisingJSONResponse), or a middleware.
