When I first thought about using either C++ or Rust for a new project, I was faced with a tough choice. Both languages are powerful, performance-oriented, and used in systems programming, but they approach things very differently. After spending time with both, I realized the decision often comes down to your priorities for the project.
I've been using C++ for years, and it's been a dependable tool for embedded systems and game development alike. You have complete control over memory with C++, which is both advantageous and disadvantageous. Although you can optimize every aspect of your code for performance, you must manually manage memory, which, if done carelessly, can result in bugs like memory leaks or segmentation faults. In my experience, I've had to spend a lot of time learning how to steer clear of these problems by employing strategies like RAII, smart pointers, and prudent resource management.
I then began to explore Rust. I was surprised by Rust's emphasis on safety and avoiding bugs at compile time. Rust's distinctive ownership system eliminates the need to worry about null pointers and data races. When I first wrote a multi-threaded Rust application, I was astounded to see that the compiler had identified possible race conditions before I had even executed the program. Rust felt far safer than C++ in terms of memory management just because of this feature.
Another significant distinction is that, in my opinion, Rust's compiler is more stringent than C++'s. The language makes you consider ownership, borrowing, and lifetimes from the beginning, which is challenging at first but ultimately beneficial because it avoids many potential issues. Although C++ offers greater flexibility in terms of what it can do, this flexibility can occasionally result in undefinable behavior that is challenging to identify.
I would suggest trying Rust for new projects if you're concerned about concurrency, safety, and contemporary tooling. The ecosystem is expanding rapidly, and although there may be a learning curve, the reliability and safety trade-off is well worth it. I feel more comfortable writing safe and concurrent code now that I'm using Rust. C++ remains a viable option, though, if you must work with an existing codebase or have a particular requirement for low-level system interactions, particularly when utilizing well-known C++ libraries or frameworks.
Ultimately, I think the choice between C++ and Rust depends on your project’s needs. If you're building something from scratch and want strong guarantees around memory safety and performance, Rust might be the way to go. If you're working with a legacy system or need maximum flexibility and control, C++ might serve you better. Either way, both languages offer incredible performance, and learning either of them will make you a stronger developer.
