Closures With Copy And Clone

[TheDarkula]

Now that closures implement Copy and Clone
Does this mean we should be able to get rid of builder.clone() calls?
Would it be as simple as adding #[derive(Clone, Copy)] to the Builder struct?

[sdroege]

can you give a code example what exactly you mean?

[TheDarkula]

I didn't have one exactly. What I was wanting to do was be able to have the Builder struct implement the Clone trait, so we don't have to use a clone! macro or do .clone() calls on it.

I couldn't track down exactly where the Builder struct was in the gtk-rs source code, but the pseudo-code would look something like this:

#[derive(Clone, Copy)]
struct Builder {
// fields omitted
}

[sdroege]

gtk::Builder is already implementing Clone. It can't possibly implement Copy as that is only possible to derive and is limited to basic types and combinations of them.
