Function xrpc_router 

pub fn xrpc_router<S: Clone + Send + Sync + 'static>() -> Router<S>

Create a new XRPC router with the standard AT Protocol error fallback.

Mount your XRPC procedures on this router, then merge it into your app:

let xrpc = atrg_xrpc::xrpc_router()
    .route("/xrpc/com.example.getPosts", get(get_posts))
    .route("/xrpc/com.example.createPost", post(create_post));
