It is yet to be determined whether or not the bun rewrite is a success, though.
What are the standards for determining that? The most obvious benefit Rust can give them is being safe from memory leaks. This is hardly controversial: it has been a Zig design choice that memory leaks are the developer/user's responsibility. They have already demonstrated to have fixed several of those [0]. Marketing-wise, it has been an obvious success. Dunno if that matters. [0] https://bun.com/blog/bun-in-rust
What's interesting tho it's that it can go from apparent marketing success to a big failure as the release keeps getting postponed.
