// In Rust, much like Go, you organize functions around structs.
#[derive(Debug)]
struct Person {
    id: u64,
    name: String,
    twitter_handle: String
}

// Here we hang a function off of a struct.
impl Person {
    // Here we make a choice to use a reference. This choice will be explored more later on.
    fn twitter_url(&self) -> String {
        return "http://twitter.com/".to_string() + &self.twitter_handle;
    }
}

fn main() {
    // str literals (e.g. "Buoyant") are slices and need to be converted into proper String objects.
    // http://www.steveklabnik.com/rust-issue-17340/#string-vs.-&str
    let stevej = Person { id: 1, name: "Steve Jenson".to_string(), twitter_handle: "@stevej".to_string() };
    // functions ending in ! are macros.
    println!("{:?} -> {:?}", stevej.name, stevej.twitter_url());
}
