Rust by Example

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();

}
