I can remove this I just wanted to remember to ask if we should be dealing with this and is there any chance this could be part of the bincode deserialization problem @MTRNord was asking about on matrix (either in the Ruma room or in matrix-rust-sdk)?

@jplatte had some ideas why bincode doesn't work I think. json does work fine (obviously. this is matrix. if it doesn't do json this wouldn't be matrix).
I still dont understand why it doesn't work with bincode :D I just removed bincode from my project

No, this has nothing to do with the bincode "expected valid JSON" error. If you want more details about that, ping me on Matrix.

I was wondering whether there would be a case like this. This now being a full copy of the response makes my whole idea moot unfortunately¹. I don't want to have worse runtime performance for somewhat nicer generated code.
I have another idea though: We could hide the repetitive
match <expr> {
Ok(val) => val,
Err(e) => return <error type>::new(<actual error>, <reponse / request>).into(),
}behind a helper function (or two, one for requests and one for responses). I hope that would make the macro code easier to read.
Does that makes sense to you? Do you have other ideas for how to make the code more readable?
¹: If you want a more in-depth explanation of why I don't think this can work (without try blocks 😄), ping me on Matrix.
Work toward issue #6
