Description:
 def request_handler(self, can_handle_func):
 # type: (Callable[[Input], bool]) -> Callable """Decorator that can be used to add request handlers easily to the builder. The can_handle_func has to be a Callable instance, which takes a single parameter and no varargs or kwargs. This is because of the RequestHandler class signature restrictions. The returned wrapper function can be applied as a decorator on any function that returns a response object by the skill. The function should follow the signature of the handle function in :py:class:`ask_sdk_runtime.dispatch_components.request_components.AbstractRequestHandler` class. :param can_handle_func: The function that validates if the request can be handled. :type can_handle_func: Callable[[Input], bool] :return: Wrapper function that can be decorated on a handle function.
