You can use futures combinators like `join`, `select`, `with_timeout` with async Rust. (crates like `embassy-futures` or `futures` have implementations of these). They work nicely even in no-std embedded.

They're different tools for different use cases. Structured concurrency is nice when doing related actions concurrently where one might need to cancel the other, while unstructured task spawning makes more sense if they're truly unrelated tasks, that live for the entire duration of the program or where you don't care for how long they live (for example concurrently handling requests in a server).
