Sure, though that's because C has abstraction like Mars has a breathable atmosphere.

This claim is wild considering that Rust code is more bug-free than C code while being just as efficient, while keeping in mind that Rust makes parallelism so much easier than C that it's stops being funny and starts being tragic.

I'm not even sure what it means for a language to "have" abstractions. Abstractions are created by competent software engineers, according to the requirements. A language can have features that make creating certain kinds of abstractions easier -- for example type-abstractions. I've stopped thinking that type abstractions are all that important. Somehow creating those always leads to decision paralysis and scope creep, and using those always leads to layers of bloat and less than straightforward programs.

& and &mut are pretty fundamental Rust abstractions.
