You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: router.rs
    path of file: ./repos/rust-template/rust+wasm/{{project-name}}/src.axum
    
    the code of the file until where you have to start completion: //! Main [axum::Router] interface for webserver.

use crate::{
    middle
    
pub fn setup_app_router() -> Router {
    let mut router = Router::new()
        .route("/ping", get(ping::get))
        .fallback(notfound_404);

    router = router.layer(axum::middleware::from_fn(log_request_response::<Logger>));

    let mut healthcheck_router = Router::new().route("/healthcheck", get(health::healthcheck));

    healthcheck_router = healthcheck_router.layer(axum::middleware::from_fn(
        log_request_response::<DebugOnlyLogger>,
    ));

    Router::merge(router, healthcheck_router)
}
