Implementing an actor to be controled from actix-web handers

[CKalt]

I have a need to provide my rest server methods that can be used to manage a remote process. I wish to do this in a way that leverages async programming. At first I had been thinking of spawning a tokio task, but I'm now feeling that was a bad idea, and that I should instead look towards launching a actix actor.

Is there a good example of how to do this I can review? How for example do I get the System struct that actix-web is using and make sure I'm being a good citizen and avoid tossing a wrench into the plumbing that actix-web depends upon?

Thank you very much for any advice on this topic.
