I think this blog post[0] describes what level of reliability you can achieve with Rust, specifically:
> In fact, Pingora crashes are so rare we usually find unrelated issues when we do encounter one. Recently we discovered a kernel bug soon after our service started crashing. We've also discovered hardware issues on a few machines, in the past ruling out rare memory bugs caused by our software even after significant debugging was nearly impossible.
For sure not everyone will be able to achieve that in their first try or when getting started, but for sure is possible, but with Node I'm not confident enough to say that, for sure if works to hack something quickly and put in online, with Rust it takes longer and there are not too many platforms yet where you can easily deploy your app.
