Just updated axum to 0.71 and everything seems fine except for some errors I get when trying to compile.

Apparently as soon as I use code like this:

/// Create a new news item for a given project.
///
async fn post_news(
    State(bs): State<Arc<BackendState>>,
    ExtractDeviceId(device_id): ExtractDeviceId,
    Valid(Json(dto)): Valid<Json<NewsNew>>,
) -> Result<impl IntoResponse, ApiError> {
    let (_, _account) = verify_device_and_account(&bs, device_id)?;
    let project = crate::projects::services::find_project_by_id(&bs, dto.project_id)?;
    let news = super::services::create_news_with_project(&bs, &project, &dto)?;
    Ok(Json(news))
}

with the following errors:

error[E0277]: the trait bound `fn(axum::extract::State<std::sync::Arc<backend_state::BackendState>>, helpers::ExtractDeviceId, axum_valid::Valid<axum::Json<news::models::NewsNew>>) -> impl futures::Future<Output = std::result::Result<impl axum::response::IntoResponse, errors::ApiError>> {news::routes::post_news}: axum::handler::Handler<_, std::sync::Arc<backend_state::BackendState>>` is not satisfied

    = note: this error originates in the macro `impl_handler` which comes from the expansion of the macro `chained_handler_fn` (in Nightly builds, run with -Z macro-backtrace for more info)

Apparently, something is not quite right with the return type that axum expects now.

Just tried 0.12.0-alpha and it seems to compile just fine now. Will report back if I see any other bugs or side effects.

Thanks for the quick response! 👍
