Rust makes multi threading very easy you can just use

thread::spawn();

But rust makes Async difficult because it’s naturally stackless so you need to create your own scheduler or use someone else’s like Tokio. Also, people have a bad habit of conflating async with concurrency which makes it more confusing.

My favourite is always;
