there's also a real world example in my see https://github.com/ttys3/static-server/blob/main/src/main.rs#L162 struct StaticServerConfig {
pub(crate) root_dir: String,
}
let app = Router::new()
.route("/favicon.ico", get(favicon))
.route("/healthz", get(health_check))
.fallback(get(index_or_content))
.layer(AddExtensionLayer::new(Arc::new(StaticServerConfig { root_dir })));and in the handler: async fn index_or_content(Extension(cfg): Extension<Arc<StaticServerConfig>>, req: Request<Body>) -> impl IntoResponse {
// ...

Oh, thanks for pointing that out! The one from tokio is definitely preferable since it doesn't involve pulling an extra dependency. |
