Could layer in one of router be used in other router after merge?

[Weijun-H]

The router structure is below

├── routers
│   ├── auth.rs (use axum-login here)
│   ├── mod.rs
│   ├── patient.rs
│   ├── router.rs
│   └── sign_up.rs

In router.rs, I tried to merge all router together,

let route = Router::new()
    .route("/admin", get(admin_handler))
    .route_layer(RequireAuthorizationLayer::<User, Role>::login_with_role(
        Role::Admin..,
    ))
    .route("/", get(protected_handler))
    .route_layer(RequireAuthorizationLayer::<User, Role>::login());

route
    .merge(sign_up::create_router().await)
    .merge(patient::create_router().await)
    .merge(auth::create_router().await)

The auth is completed in auth, and other router need to be checked.
When I ran the program, the server could not find extention. And showed

thread 'tokio-runtime-worker' panicked at 'Auth extension missing. Is the auth layer installed?', 

Should I use other functions, instead of merge? Does anyone give me some advice? Thanks.

Nope. Then you need to add the layer after merging: .merge(...).merge(...).layer(...)
