Can we use async

[harshkumar314e]

I am trying to use a external crate casbin for authorization, the initialize method of enforcer is async by nature. I am using OnceCell to store the resultant enforcer. Apart from this the enforce method is sync only.

Is there any way to call this async fn and do polling, or any other method to achieve the same thing. I tried block on of futures crate and also tried creating builder from tokio's runtime, but got error that polling is not supported.

Any solution or comment? Thanks in advance.
