Thanks for the clarification. That makes sense.
Can I have another clarification please. I have some rust code currently
that looks like this:
// a type that should not be copied implicitly because it is mutable
class fat {
let mut doughnuts: int;
new(){
self.doughnuts = 99;
}
}
trait fat_methods {
fn shizzle();
}
impl of fat_methods for fat {
fn shizzle() {
io::println("yo shizzlin");
}
}
fn main() {
let x = fat();
x.shizzle();
}
One way to change this code would be to make the impl for &fat rather
than for fat, and change x's expression to &fat(). Luckily this also
seems to allow calling methods on @fat and ~fat types. Is this a
reasonable way to migrate the code? Are their alternatives?
Thanks
Gareth
