Depending on what you mean exactly I think Rust can be considered pretty close to the hardware. I.e. there's usually an obvious straightforward translation of each line of source code to an implementation in assembly language (which may not be what's actually emitted in practice due to optimizations, but the same is true in C).
There are of course some higher-level features like trait-based generics, so it's not really as close to the machine as C, but it's a lot closer to C IMO than something like Java (or even C++).
