Asterinas: OS kernel written in Rust and providing Linux-compatible ABI

I personally dislike rust, but I love kernels, and so I'll always check these projects out.

This is one of the nicer ones.

It looks pretty conservative in it's use of Rust's advanced features. The code looks pretty easy to read and follow. There's actually a decent amount of comments (for rust code).

Not bad!

Otherwise is a decent language but what makes it difficult is the borrow semantics and lifetimes. Lifetimes are more complicated to get your head around.

But then there's this Arc, Ref, Pinning and what not - how deep is that rabbit hole?

If you’re writing C and don’t track ownership of values, you’re in a world of hurt. Rust makes you do from day one what you could do in C but unless you have years of experience you think it isn’t necessary.

Okay, I think it is is more like Typescript. You hate it but one day you just write small JS program and convert it to Typescript to discover that static analysis alone had so many code paths revealed that would have resulted in uncaught errors and then you always feel very uncomfortable writing plain Javascript.

But what about tools like valgrind in context of C?
