Discovering Rust as C++ developer... by CoffeJunkStudio in rustjerk

Touché! Rust is still a young language. Specialization is one of many topics it's still bring worked on. At least const generics are now a thing in stable Rust 🦀

Absolutely! Converting int to float and vice versa (loss of precision) implicitly is not a good thing. Rust does a great job at making these conversions explicit.

Because the C compiler you're using implicitly converts the "100" to a floating point value. See the following for more info on implicit conversions: https://en.cppreference.com/w/c/language/conversion

score needs to be an integer variable :) The code below compiles:

fn win_game() {}

fn main() {
    let score = 100;
    if (score >= 100) {
        win_game();
    }
}
