A half-hour to learn Rust

This would work if `Integer` would implement the `Copy` trait. But I guess that type is heavy enough for it to be too expensive, therefore forcing you to explicitly call `clone()`.

That `Integer` type can't implement `Copy` because it manages a resource, meaning you can't just do a simple memcpy of the type.
