It's not all brilliant though, there's still a lot of useful tooling that Rust needs to develop to make it really nice, e.g. there's no nice way to create a C header file describing a Rust library (since C headers are the lingua-franca of FFI libraries, in many ways), https://github.com/rust-lang/rust/issues/10530 .

And, being a young language, it's not too hard to be doing something no-one else has ever done, especially with this low-level stuff. :) (Meaning compiler bugs and some "I don't know" answers.)
