Running Futures

Riker can execute and drive futures to completion. In fact, internally actors are executed as futures by the dispatcher. This means Riker can run any future on the same executor, alongside actors.

ActorSystem and Context both have a run method that takes a future to run:

let handle = system.run(async move {
    "someval".to_string()
});

assert_eq!(block_on(handle), "someval".to_string());

sys.run schedules the future for execution it will drive it to completion utilizing the dispatcher's thread pool. run returns a futures::future::RemoteHandle future that can be used to extract the result.

Note

Riker executes futures using the Futures crate's futures::executor::ThreadPool.

In the next section we'll see how to to test Riker applications.
