You get very few of the Rust guarantees when you litter your code with unsafe to get around the safety checks (which is what they're doing here). I would not recommend running this in production.
Yes, liberal unsafe code makes in Rust it arguably worse than writing it in a presumed-unsafe language.
From what I understand, rust "unsafe" is actually pretty damn safe compared to an actually memory unsafe language.
Not really. In fact unsafe Rust is widely considered to be significantly harder to get right than C or Zig.
E.g. see https://chadaustin.me/2024/10/intrusive-linked-list-in-rust/ or https://lucumr.pocoo.org/2022/1/30/unsafe-rust/
The saving grace is that in idiomatic Rust code you have very little unsafe code - usually none. But yeah there's no way I would trust AI to get unsafe Rust right.
It's unsafe
