I agree, Rust's documentation is really awful at the moment. I mean, there's a reason for it: the syntax and semantics are evolving so fast that any tutorial written right now will be hopelessly out of date in two weeks (note that the official tutorial has been updated regularly, but you can't even tell!), and much of the current stdlib is comprised of quick hacks based on obsolete language features and may very well get near-entirely rewritten before 1.0. Of course, that's no consolation for people who don't consistently lurk in the dev channels.

There's some hope, though. The next release (0.4, due in perhaps a month) has been tentatively designated as the "syntax freeze" release, so at the very least things should cool down after that point (fingers crossed). But until then, I wouldn't advise newcomers to get anywhere near Rust, for fear of the constant breaking changes that are leading up to the syntax freeze.
