I honestly don't. It was a real question.

The only times I had to use third party packages for basic stuff, was when developing embedded software on limited hardware.

Do you mean that for async we need third party runtimes like tokyo? Or that types and utilities that many other languages ship by default in stdlib, like http aren't in rusts?

I'm sorry for the tone of my post. It was meant as honest surprise, but I clearly see now how it sounds baity and provoking.
