Yes, that's it! Are these migration-related questions suited for this list or should I use github issues? thanks again, steve On Sat, Dec 22, 2012 at 10:28 AM, Tim Chevalier catamorph...@gmail.comwrote: On Sat, Dec 22, 2012 at 10:27 AM, Steve Jenson ste...@fruitless.org wrote: In 0.4, I had a struct that stored a fn that I later called as if it were a method.

The list or IRC is great for asking questions where you don't think there's a compiler bug. So you're doing it right :-) Cheers, Tim -- Tim Chevalier * http://catamorphism.org/ * Often in error, never in doubt We know there'd hardly be no one in prison / If rights to food, clothes, and shelter were given. -- Boots Riley ___ Rust-dev mailing list Rust-dev@mozilla.org https://mail.mozilla.org/listinfo/rust-dev
