How to clone RouteContext<()>?

[makorne]

Hi all!

// #[derive(Clone)]   // It needs Clone but RouteContext does not have Clone :(
struct AppState {
    ctx: RouteContext<()>  //Container for a route's parsed parameters, data, and environment bindings from the Runtime (such as KV Stores, Durable Objects, Variables, and Secrets).
}

pub async fn handler(
    request: HttpRequest,
    ctx: Extension<RouteContext<()>>,
) {}

#[event(fetch, respond_with_errors, http)]
pub async fn main(
    req: worker::HttpRequest,
    env: worker::Env,
    _ctx: worker::Context,
) -> Result<axum::response::Response> {

    let mut app =
        axum::Router::new().route("/", axum::routing::get(handler))
            .with_state(AppState {ctx: env.ctx});

    app.call(req)
        .await
        .map_err(|e| worker::Error::from(e.to_string()))
}

Error:

axum::Router::new().route("/", axum::routing::get(handler)).with_state(AppState {ctx: env.ctx});
    |                                        ------------------ ^^^^^^^ the trait `Handler<_, _, _>` is not implemented for fn item `fn(http::Request<worker::ByteStream>, Extension<worker::RouteContext<()>>) -> impl Future<Output = ()> {handler}

How to use KV Stores in axum handlers?

You need to implement the trait Handler for RouteContext, I’m not sure what that is but I’m sure it’s from Axum.
