Compared to Go:
* Rust does not have NULL!!
* Rust has parametric polymorphism.
* Rust has more predictable memory/cpu usage thanks to forgoing global GC for a novel memory management model based on stack allocation/RAII, immutability, isolated processes and reference counting.
* Rust has a very Erlang-like model of handling failures.
* Rust has typestate, which is an easy to use way of proving properties about your program statically, or check them dynamically via assertion.
* Rust has no shared mutable state.
Those are facts. My personal, more subjective, opinion is that Rust is a lot better thought out than either D or Go. If this niche is too crowded, I'd rather see them go and Rust win. :) But given that Rust lacks shared global GC, I guess you could say it's closer to C++
