Zero-cost futures in Rust

1. I am not sure exactly how async/await is implemented, but I believe it is very similar. Some people are also working on implementing similar sugar in Rust, but it's not done yet.

2. Closures are on the stack, not the heap, by default, in Rust. If you don't see a Box, they're not heap allocated.

3. I agree!

Stack-allocated closures are one of my favorite features of Rust. They make it easy to write functional-style code that performs well.
