So what's the best way to install Rust on OSX and get something half portable? Just the official installer? Hand-bomb the official binaries somewhere?

^^^ pretty much the conclusion I came to. I'm also a Rust newb.

You can also match on self and do roughly the same thing but it's very unwieldy.

I also wouldn't mind seeing more words about lifetimes. The official book is pretty brief about them. Like, both of these work:

code:
#[derive(Debug)]
struct Butt<'a> {
    fart: &'a i32,
    poop: &'a str
}

fn main() {
    let dilz = &32;
    let dong = "balls";
    
    let rear end = Butt{fart: dilz, poop: dong};
    
    println!("My butt: {:?}", rear end);
}
code:
#[derive(Debug)]
struct Butt<'a, 'b> {
    fart: &'a i32,
    poop: &'b str
}

fn main() {
    let dilz = &32;
    let dong = "balls";
    
    let rear end = Butt{fart: dilz, poop: dong};
    
    println!("My butt: {:?}", rear end);
}
What the heck is the difference? Would you ever actually need more than one explicit lifetime for a struct?
