Rust doesn’t even have a real GUI library yet, let alone support from common game libraries. C++ supports a hundred times as many compilation targets and platforms.
I agree that the gaming industry is a place where starting a C++ project still makes sense.
Earlier quoted context omitted.
Interesting, haven’t heard this viewpoint before of Rust being a drop in replacement for Java. From my limited experience with Rust it felt like the learning curve was way steeper than when I was learning Java for my previous job. Good point on C though, one of my old CS instructors would always call C his swiss army knife since its so small he had practically the entire syntax in his head.
OP never said rust was a drop in replacement for java
Mature Libraries: C++ has a treasure trove of well-established libraries. For niche or legacy needs, C++ might be your only option. Performance Control: When you need to micro-manage performance, C++ gives you the nitty-gritty control that can make all the difference. Industry Norms: In some fields like game development, C++ isn't just preferred, it's expected. Sticking to industry norms can sometimes outweigh the benefits of newer tech. So, while Rust has its perks, especially around safety and concurrency, C++ still holds its ground where its deep-rooted ecosystem and granular performance control come into play.
It's really difficult to evaluate a hardware product with only a C(++) SDK using only Rust. There are of course ways around this but those are a significant amount of effort.
In terms of GUIs - there's simply no "Qt-Rust" that would work in a Rust-y way without causing massive headaches. Handling all that state is incredibly difficult in Rust, at least for me (but I recall others describing why as well).
The best way to think of Rust as essentially the new Java, which sort of "won" over C++ due to its more strict syntax with mandatory OOP and code patterns. Rust enhances this by running most of the checks in the compiler so you get native code, with very few runtime additions for type safety. But just like Java, its almost useless to code in it for personal or smaller projects. For almost all of my projects where I n…
> But just like Java, its almost useless to code in it for personal or smaller projects. That's entirely the opposite from my experience. Rust is a pleasure to code in for personal projects once you're familiar with the language, especially compared to C/C++. Managing dependencies is more straightforward, and there are a lot of crates out there to make writing your project easier.

>> C++ supports a hundred times as many compilation targets and platforms. I would not want to be the one writing that CMakeLists.txt
If you want to create any real-time graphics application (video games, game engines, CAD software, visualization, etc.), or do any sort of scientific computing / HPC. The graphics ecosystem in Rust is still too undeveloped to see adoption (for the graphics API people are converging towards WebGPU, but it's still no match to Vulkan / DX12 / Metal), same goes for any GPGPU computing. Rust is also currently lacking in d…

I seem to be writing an OS with it just fine.
I've personally stumbled upon two - obscure hardware and GUIs. It's really difficult to evaluate a hardware product with only a C(++) SDK using only Rust. There are of course ways around this but those are a significant amount of effort. In terms of GUIs - there's simply no "Qt-Rust" that would work in a Rust-y way without causing massive headaches.
