You’re missing the point. Tools are different. Trying to learn and use rust by writing unsafe bubble sorta is pointless. Use it to actually accomplish something and you’ll find out just how amazing it is.
Using the ecosystem that exists to be productive and not have to think at all about whether what you’re doing is correct is the point. It catches the subtle errors for you and lets you use the powerful libraries like clap for command line parsing, tokio, etc.
