In general I like languages having some form of common code formatting style, as long as it's sane. Things like putting { on own lines is not sane, but I think everyone agrees on that by now.
Rust has its own style too and at least the defaults are at times absolutely horribly ugly. I hate wasting lots of vertical space for function parameters like in this example. I have not yet found a way to bring som sanity to this abomination, but I hope it can be done.
