I thought I would teach myself Rust, apparently can't get Python out of me

Text description (for those with screenreaders):

A portion of a prime number checker written in the Rust programming language, where the first few lines are written correctly including the first if statement in the program. However, the following if statements are written using Python syntax instead of Rust, as the author slipped back into his native tongue.

That's why you use a proper IDE, that checks everything as you type.
- Yeah, like Vim. Who uses nano to code?
  
  Well, in my defense I just wanted to initially try out Rust and on this particular computer, I don't have any IDE set up on it yet. However, definitely seems like an IDE is in order for me haha
  
  I did not realize nano implemented syntax highlighting!
- Seriously. I can't imagine writing rust without an IDE, that's absurd. Rustrover is amazing
  
  What is Rustrover? Whatever it is, that's an awesome name
- I was pleasantly surprised by how good the error messages are in Rust though on compile time. I agree that having an IDE flag them before I compile is much better though.
Once you're happy with your own implementation, you may be interested in this rather rustic implementation I created a little while ago: https://codeberg.org/trem/erastothenes-iter/src/branch/master/src/lib.rs
It's actually just an iterator for primes, but building a function around it which checks whether a given number is prime shouldn't be difficult.
It's probably quite overwhelming, but you don't have to learn all these concepts all at once. I started out much like you and then learnt many of the nuances hidden in there over the course of multiple years. It's fine, if it doesn't look all idiomatic from the start. Just as a bit of a pre-taste where your journey might lead. 🙃
