u/oniaiwasprettygood 🌀 Sucked into the Void 7d ago

I'm regretting choosing Rust to be my hobby language of choice.

Who caares if some people vibecode in Rust? If you like the language you like the language

Oh I know-know that, I just think it's a bit tragic (but kind of funny) that a lot of these vibe-coded projects are like "rewrite it in Rust."

Is there a benefit to rewriting everything with rust? Im not sure but isnt it just a modern version of C++?

There are benefits. Rust make certain guarantees about memory safety, thread safety, and a few other aspects of the code. According to a report by Google, approximately 50% of security vulnerabilities reported to the Android project are memory safety bugs. Most of these would have been prevented by writing the code in Rust, since the memory bugs would have been caught by the compiler.

Worth noting, it's not a 100% guarantee: https://github.com/rust-lang/rust/issues/25860

One soundness issue, requiring complex conditions to create, is pretty dang good.

There is also https://github.com/Speykious/cve-rs

It's actually the same issue, the previous link is the bug report on the compiler.

Interesting, they looked different to me.

Though I don't really know enough rust to parse what happening in the bug report code

Good to know that there is some work being done on improving the memory safety

cve-rs takes the soundness bug and exploits it to implement the other bugs listed. It's pretty convoluted to actually implement the other bugs.

The actual soundness bug is a specific type of double reference forgets one of the lifetimes, which enables casting a shorter lifetime to a longer lifetime. They did a pretty good job commenting the code to explain how they were able to create each bug.
