Falcon now works on RustPython out of the box #7957

import wsgiref.simple_server

import falcon
import falcon.asgi


class HelloWorld:
    def on_get(self, req: falcon.Request, resp: falcon.Response) -> None:
        resp.media = {'message': 'Hello, World'}
    
class AsyncHelloWorld:
    async def on_get(self, req: falcon.asgi.Request, resp: falcon.asgi.Response) -> None:
        resp.media = {'message': 'Hello, World'}


app = falcon.App()
app.add_route('/hello', HelloWorld())

asgi_app = falcon.asgi.App()
asgi_app.add_route('/hello', AsyncHelloWorld())

if __name__ == '__main__':
    with wsgiref.simple_server.make_server('', 8000, app) as httpd:
        print('Serving WSGI app on port 8000...')
        httpd.serve_forever()
