Arduino has the benefit of several years of refinement and an all-in-one, multi-target library. Embedded Rust is still in its infancy, though it's absolutely usable and (imo) practical for experienced users. I think as the embedded abstractions get polished and there is more convergence of HALs, something like an all-inclusive solution may come about. As it stands, it's very easy to combine a chip HAL and device drivers, but you have to know what building blocks to grab (if they're there - there's lots to be done!).
