Im trying to write req guard that will either return user_id: String or just terminate request with Status::Unauthorized

use rocket::request::{Request, FromRequest, Outcome};
use rocket::outcome::IntoOutcome;
use rocket::{async_trait};
use rocket::http::Status;

use mongodb::bson::doc;


// modules
use crate::DB;
use crate::user_module::user_model::UserModel;





struct Auth {
  
}



#[async_trait]
impl<'r> FromRequest<'r> for Auth {
  type Error = ();



  async fn from_request(req: &'r Request<'_>) -> Outcome<String, ()> {

    let db = DB.get().unwrap();
    let users_collection = db.collection::<UserModel>("users");
    


    req.cookies()
      .get_private("user_id")
      .and_then(|cookie| cookie.value().parse::<String>().ok())
      .or_forward(Status::Unauthorized)




  }



}

The problem is… it always gives me an error, doesn’t matter what i’m changing

Right now, problem is

method `from_request` has an incompatible type for trait
expected signature `fn(&'r rocket::Request<'_>) -> Pin<Box<(dyn std::future::Future<Output = Outcome<guards::Auth::Auth, (Status, ()), Status>> + std::marker::Send + 'async_trait)>>`
   found signature `fn(&'r rocket::Request<'_>) -> Pin<Box<(dyn std::future::Future<Output = Outcome<std::string::String, (Status, ()), Status>> + std::marker::Send + 'async_trait)>>`

and i have no idea what this is about

The guide i found is… idk incomplete? Where is struct?
