Hi Jeremy, I'd love to hear what your thoughts are on Rust after building something like this. As someone who's relatively new to both Rust and OS development, I'm curious what some of the challenges have been around core data structures often found in kernels where ownership can be ambiguous or complex, and developing without the support of a runtime/standard library. Has Rust passed the acid test of OS development in your eyes?

View on HN

core is very comprehensive and alloc adds dynamic allocation once your kernel supports a heap. The complicated data structures in kernels are much easier to write in Rust, in my opinion. And you can be certain of their consistency when you have multiple cores running kernel code because of the ownership model.

I prefer doing bare metal development in Rust if possible

Redox looks very interesting. It seems one good approach might be to force new apps and drivers for Redox itself, but provide a VM environment that would run sandboxed Linux and other OS's securely. (Similar to the Qube OS idea.)

That way Redox could offer a considerably improved API and app development environment without worrying about backward compatibility, while being useful as a daily driver in the meantime.
