Getting Error on upgrading the version of the ntex to 0.5

[SiddheshKanawade]

I am getting the following error after I upgraded the version of the ntex. Not sure where I am going wrong or how to resolve it?

The dependencies in Cargo.toml looks like:

[dependencies]
ntex = "0.5"
casbin = "2.0.9"
dotenv = "0.15"
loge = {version = "0.4.2", default-features = false, features = ["colored", "chrono"]}

The repository I am working can be found here

[SiddheshKanawade]

The above issue got sorted when I added feature to ntex in Cargo.toml. The file now looks like:

[dependencies]
ntex = { version = "0.5", features = ["tokio"] }
casbin = "2.0.9"
dotenv = "0.15"
loge = {version = "0.4.2", default-features = false, features = ["colored", "chrono"]}

Now I am getting the following error:

The relevant code is

#[ntex::main]
async fn main() -> io::Result<()> {
    dotenv::dotenv().ok();

    loge::init();

    let model = DefaultModel::from_file("acl/acl_model.conf").await.unwrap();
    let adapter = FileAdapter::new("acl/acl_policy.csv");

    let e = Enforcer::new(model, adapter).await.unwrap();
    let e = web::types::Data::new(RwLock::new(e)); // wrap enforcer into actix-state

    //move is necessary to give closure below ownership of counter
    web::server(move || {
        App::new()
            .app_data(e.clone()) // <- create app with shared state
            // enable logger
            .wrap(middleware::Logger::default())
            // register simple handler, handle all methods
            .service((
                web::resource("/auth").to(auth),
                web::resource("/auth/{name}/{action}").to(auth),
            ))
    })
    .bind("127.0.0.1:8080")?
    .run()
    .await
}

According to the official docs, app_data is a valid method
Also, there isnt any documentation available for app_state

[fafhrd91]

use web::types::State instead of Data

[SiddheshKanawade]

Thankyou, this removes the deprecated warning.
Also, I have changed app_data -> app_state, since it seems that app_data is no longer available, correct me if I am wrong :)
