alt Hacker NewsMu. Invalid question. Rust doesn't disable compiler features. It gives you extra set of footguns when you ask for it.
As for the actual unloaded question, "What's the point of unsafe in Rust?" it is to contain and make it easier to identify sources of UB.
The whole point of the rust rewrite is that bun is now thought to rely on rust’s memory safety features, but that assumption doesn’t hold if everything’s inside an unsafe block.
