Example
use poem::{
get, handler, http::StatusCode, middleware::AddData, web::Data, Endpoint, EndpointExt,
Request, Route,
};
#[handler]
async fn index(data: Data<&i32>) {

}
let app = Route::new().at("/", get(index)).data(10i32);
let resp = app.get_response(Request::default()).await;
assert_eq!(resp.status(), StatusCode::OK);
