Is it worth it using Rust+Axum for backend instead of Node.js? In which situations would you do so?

I did this. Further reasons are: correctness and performance.
Rust is much faster while at the same time using a fraction of the resources the equivalent Spring Boot implementation would use. The type safety and being freed from runtime errors is awesome as well. Yes initial development takes longer, but I believe it is worth it. Most projects spend maybe 2% on initial development, 98% is bugfixing, troubleshooting, refactoring. I am confident Rust cuts down on bugfixing by 2/3, which means doubling the initial dev time is well worth it. And it doesn't even take twice as long.
For very simple backends, it's very unlikely you'll get any significant number of bugs with an experienced team, and if performance isn't really a concern, then Rust being faster isn't really relevant. For anything more complex than a simple backend, I'd agree that Rust becomes a lot more appealing, but if you just need to throw together something that handles user profiles or something in a very simple manner, it really doesn't make a difference what language you do it in as long as you write a few tests to make sure everything works.
Agreed!
