And the rust code is littered with unsafe blocks, the Rust version has not been vetted and there's no guarantee it'll actually be better long term than zig. Don't buy the hype, the only reason it was re-written in Rust is because Zig took a firm no AI stance, and Bun is owned by anthropic.

Writing Bun in Zig was already a mistake from the start, because it was too immature to fully commit on the large scale. Zig is not guaranteeing backwards comparability, and it's stability is tied to the whims of Andrew Kelley.
