Ahh, that's cool, I didn't realize Rust could do that. Though it does still require you to write the thing that tells the compiler their type implements your interface, right? Not a huge deal, but it's still essentially like writing a wrapper (though perhaps not as huge?) Also, it sounds like you can't implement a third party trait on a third party type, so you can't use bill's cool log writer in joe's cool log roller.
