I think that a line-for-line rewrite in Rust like Bun did isn’t really getting all of the benefits of using Rust. A key benefit is utilizing the type system to make the borrow checker work for you by making certain checks happen at compile-time instead of runtime. Making it impossible for certain mistakes to occur is a massive benefit but you need to restructure everything to do so.

I understand that's a guest post in Jetbrains blog, and these guests could very well be real people, project maintainers, conference speakers and whatnot, but I feel they used LLM so heavily that it reads like a slop. Pease do better next time.
