Now, off-topic: I've been trying to post the following question to this mailing
list for like 4 times, but no dice. I seem to have better luck when replying to
posts, so here it goes:
struct Value {
n: int
}
impl Value {
fn squared(mut self) -> Value {
self.n *= self.n;
self
}
}
fn main() {
let x = Value{ n: 3 };
let y = x.squared();
println!("{} {}", x.n, y.n); // prints 9 9
}
self isn't being passed by value to squared, since x.n gets mutated as well.
This must be a bug, right?
That is not what I'd expect, in any case!
;-)
PS: cannot run the code, get:
_.rs:12:16: 12:19 error: found `self` in ident position
_.rs:12 fn squared (mut self) -> Value {
^~~
??? (also, underlining looks wrong; unless the actual error is about mut?)
