alt Hacker NewsYou didn't mention parametric polymorphism, which is incredibly useful and important to the language. I'm guessing you intentionally excluded async, but to describe it as "not that useful" would just be wrong, there is a large class of programs that can be expressed very simply using async rust but would be very complicated to express in sync rust (assuming equivalent performance).

Generics are incredibly overused in rust like most other features. I’m pretty sure most programs don’t need generics outside of use cases like HashMap

Yes rust async isn’t good imo. You can do basically the same thing with stackfull coroutines.
Also the ecosystem is setup so you have to use tokio and everything has to be an Arc.
