For example, if I had a Python function like this:\r\n\r\n```python\r\nclass Input(TypedDict):\r\n  type: Literal[\"http\"]\r\n  status_code: int\r\n  method: Literal[\"GET\", \"PUT\"]\r\n  callback: Callable[[], None]\r\n\r\nclass Output(TypedDict):\r\n  message: str\r\n  callback: Callable[[], None]\r\n\r\ndef process(inp: Input) -\u003e Output:\r\n  assert inp[\"type\"] == \"http\"\r\n  status_code = input[\"status_code\"]\r\n  assert 99 \u003c status_code \u003c 600\r\n  method = input[\"method\"]\r\n  assert method in (\"GET\", \"PUT\")\r\n  msg = f'{method} {status_code}\"\r\n  return Output(message, inp[\"callback\"])\r\n```\r\n\r\nThis crate is super convenient to parse and validate `type`, `status_code` and `method` since you can make a declarative serve model for this:\r\n\r\n```rust\r\n#[derive(Serialize, Deserialize]\r\n#[serde(rename_all = \"UPPERCASE\")]\r\nenum Method {\r\n  Get,\r\n  Post,\r\n}\r\n\r\n#[derive(Serialize, Deserialize]\r\nstruct HTTPMessage {\r\n  status_code: u32,\r\n  method: Method,\r\n}\r\n\r\n#[derive(Serialize, Deserialize]\r\n#[serde(tag = \"type\")]\r\nenum Message {\r\n  Http(HTTPMessage),\r\n}\r\n```\r\n\r\nBut as far as I can tell there is no way to say \"make the `callback` key a `Py\u003cPyAny\u003e`. In other words, something like:\r\n\r\n```rust\r\n#[derive(Serialize, Deserialize]\r\nstruct HTTPMessage {\r\n  status_code: u32,\r\n  method: Method,\r\n  callback: Py\u003cPyAny\u003e,\r\n}\r\n```\r\n\r\nIs that right?","author":{"url":"https://github.com/adriangb","@type":"Person","name":"adriangb"},"datePublished":"2022-11-07T18:02:11.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/32/pythonize/issues/32"}
