    RWIIR!!!

    edit: here, I did it for you:

    use std::*;

static mut sucked: bool = false;

fn main() {
        unsafe {
                check_sucked();
        }
        println!("Kris has been sucked is {}", sucked)
}

unsafe fn check_sucked() {
        if !sucked {
                suck();
        }
}

fn suck() {
        sucked = true;
}

    edit 2: fixed it

            oh well, I’m just starting to learn the language and come from java, so I thought: wait, it can’t be static

              const is more like C++ constexpr, but static is similar to static from C: it’s a variable that lives outside any scope. Of course, that means the same static can be accessed by multiple threads, so writing to a static is unsafe (except for types like Mutex, you can safely use those to write, but your static won’t be declared mut)
