# Methods

Methods are annotated similarly to functions:

    struct Owner(i32);

    impl Owner {
        // Annotate lifetimes as in a standalone function.
        fn add_one<'a>(&'a mut self) { self.0 += 1; }
        fn print<'a>(&'a self) {
            println!("`print`: {}", self.0);
        }
    }

    fn main() {
        let mut owner = Owner(18);

        owner.add_one();
        owner.print();
    }
