In practical perspectives, I’m mostly concerned about computer resources usage; I have computer resources constraints. So using Rust would benefit on that. But it is for a Web application backend. So, it is worth it having to learn Rust + Tokio + Axum, … in this specific situation. Also, that this is mostly for initially prototyping an application.
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!
