Type alias

---

• We can use the type keyword to create aliases to existing types. This can help us in reading the code, but Rust does not do any enforcement.
• As you can see in the following example we can pass arguments to a "different" type as long as it is an alias to the same type.

type Meters = u32;
type Kilograms = u32;

fn main() {
    let m: Meters = 3;
    let k: Kilograms = 4;
    calc(m);
    calc(k);
}

fn calc(y: Meters) {
    println!("{y}");
}
