Why asynchronous Rust doesn't work
Note that you don't need a closure in Rust to start a thread. You can just specify a function to be called (because functions implement FnOnce).

Thanks. My question emerged from the fact that all the Rust threads examples I see are in the closure form
|| {}
.

Because the closure form is much more useful. You very rarely want to create a thread without first passing some state to it, and environment-passing with closures is a brilliantly ergonomic way to do this.
