Depends on if you're coding for critical infrastructure (i.e. - electrical grid), or writing a high performance video game that can run on older hardware.
We should absolutely have specific licenses like Civil Engineers do for computer infrastructure that is required for any software written for specific purposes. It would be a nightmare to implement, but at some point, it's going to be needed.
Unless it's some really exotic platform, I'd honestly still say no. Rust has shown that memory safety and performance doesn't have to be a tradeoff. You can have both.
But sure, if whatever you're targeting doesn't have a Rust compiler, then of course you have no choice. But those are extremely rare cases these days I'd say.
I don't even think we really need to eek out every MHz or clock cycle of performance these days unless your shipping code for a space vehicle or something (But that's an entirely different beast)
We've got embedded devices shipping with 1GHz+ processors now
It's just time to move on from C/C++, but some people just can't seem to let go.
The Rust community has 2 websites that I keep periodically checking: Are we game yet? and Are we GUI yet?. The answers on those sites are respectively (as of February 2024, when this comment is written) "Almost. We have the blocks, bring your own glue" and "The roots aren't deep but the seeds are planted". I've seen the progress in Bevy and Slint, but it's still the same, those websites don't change, and my situation WRT to making a Rust project for fun or work it's the same.
I'll be happy to start doing Rust projects whenever I get the chance (which will be when it's a sufficient tool for my use cases). But I'm tired of smoke sellers.
Have you actually tried making a GUI or a game? I don't think you can summarize the state of the whole ecosystem in a sentence that doesn't change in years. I've made perfectly functional GUIs with iced, and imgui. Haven't tried slint yet.
Godot is a very popular game engine and it's written in rust, so you probably can use it in rust.
Godot is written in C++ not Rust…
That's true. I might've gotten confused because I saw godot rust bindings.
I've wanted to start a project in Rust, but for the ideas that I have (and the time that I have for a hobby project, as for work it's rarely starting a new one, but continuing and existing one), Rust seemed a viable, but not ideal alternative to just doing it all in C++, for which I already have enough knowledge and very well proven libraries. I will look again soon, and I will keep looking because eventually something will surely click, it's just that so far, the time has not been right.
Note that my point is not that it's unusable for everyone. Just that it's false that "some people just can't seem to let [C or C++] go", as the previous comment said. I can't let go something that works well for something that doesn't, given the projects that I have to work on.
