Inferring the response type of a handler

import type { Env } from "@/types";
import { createFactory } from "hono/factory";
import { InferResponseType } from "hono";

const factory = createFactory<Env>();

export const helloWorld = factory.createHandlers(async (c) => {
  return c.json({
    message: "Hello World",
  });
});

type Route = typeof helloWorld[0]
type RouteResponse = Awaited<ReturnType<Route>>;
type Foo = InferResponseType<RouteResponse, 200>

type RouteResponse = void | Response | (Response & TypedResponse<{
    message: string;
}, ContentfulStatusCode, "json">)

type Foo = never
