pub: + ? + &' to simplify public structs

current.rs

#[deriving(Show)]
pub struct Stuff<'a> {
    pub desc: &'a str,
    pub owner: Option<&'a str>,
    // pub borrower: Option<&'a str>,
    pub using: Option<&'a str>,
    pub key_to: Option<&'a str>,
    // pub left_hand: Option<&'a str>,
    // pub right_hand: Option<&'a str>,
    // pub mother: Option<&'a str>,
    // pub father: Option<&'a str>,
    pub strength: i32,
    // pub lift_strength: i32,
    // pub push_strength: i32,
    pub money: i64,
    pub time: i64,
    pub speed: i32,
    pub locked: bool,
    // pub influence: i32,
}

new.rs

#[deriving(Show)]
pub: struct Stuff {
    desc: &'str,
    owner? &'str,
    // borrower? &'str,
    using? &'str,
    key_to? &'str,
    // left_hand? &'str,
    // right_hand? &'str,
    // mother? &'str,
    // father? &'str,
    strength: i32,
    // lift_strength: i32,
    // push_strength: i32,
    money: i64,
    time: i64,
    speed: i32,
    locked: bool,
    // influence: i32,
}

A colon after pub makes all the members public.

A question mark instead of : wraps the type in Option.

A &' is a short hand for "lifetime to this struct".
