Hey I updated actix-web to 4.0.0-beta.1 in the Cargo.toml file,
actix-web = { version = "4.0.0-beta.1", default-features = false }

But then the tests fail:

error[E0277]: the trait bound `CasbinService: actix_web::dev::Transform<actix_web::app_service::AppRouting, ServiceRequest>` is not satisfied
  --> tests/test_middleware.rs:90:19
   |
90 |             .wrap(casbin_middleware.clone())
   |                   ^^^^^^^^^^^^^^^^^^^^^^^^^ the trait `actix_web::dev::Transform<actix_web::app_service::AppRouting, ServiceRequest>` is not implemented for `CasbinService`

error[E0277]: the trait bound `FakeAuth: actix_web::dev::Transform<<impl actix_service::ServiceFactory<ServiceRequest> as actix_service::ServiceFactory<ServiceRequest>>::Service, ServiceRequest>` is not satisfied
  --> tests/test_middleware.rs:91:19

Couldn't find actix_web::app_service::AppRouting and ServiceRequest is implemented as a type. What could possibly be the problem here?

@smrpn You can refer the doc of actix-web, see what's the breaking change in actix-web 4.0
