A reminder of what the chained function calls look like that process the returned value from the actor

main.rs

// Send message to `DbExecutor` actor
req.state().db.send(GetConspiracy{page_id: page_id.to_owned()})
    .from_err()
    .and_then(|res| {
        match res {
            Ok(conspiracy) => Ok(HttpResponse::Ok().json(conspiracy)),
            Err(_) => Ok(HttpResponse::NotFound().into())
        }
    })
.responder()
