Support generics in route handlers?

[Jaltaire]

When trying to apply the #[oasgen] macro to a route handler like this:

#[oasgen]
pub(super) async fn version_post<D>(
    State(_state): State<AppState<D>>,
    Json(payload): Json<RequestBody>,
) -> Result<OkResponse, ErrResponse>
where
    D: Debug,
{
    // route handler implementation
}

We get an error: Cannot find type "D" in this scope.

Is it possible to add retention of generics to the #[oasgen] macro generation?

Definitely. Unfortunately I don't have much time to maintain the lib beyond accepting PRs. If you tackle this (or have AI do so - I imagine it would do well), happy to merge it in.
