Basically D provides safety, but it also provides means to do unsafe things. I'm not familiar with Rust, but I wouldn't be surprised if unsafe actions could also be taken.
Haha, he covers that in the next section, just before I stopped reading to reply.
"Rust still provides an escape hatch to allow students to experiment with unsafe code."
So realy Rust requires safety by default while D allows unsafe code by default. This leads me to believe that the reason Rust is safer is three fold, the SafeD system (@safe, @trusted, @system) isn't fully implemented, not enough libraries are marking @safe, and we don't have a good library to encapsulate the unsafe manual memory management (a library could probably get pretty close to what Rust's compiler does).
