Which is better Rust or C++? [CLOSED]

Question

I've been researching about secure way to code and with a good performance.

I found various articles on web saying Rust out performs C++ in performance and is also secure as it has different functions for safe and unsafe handling.

My main concern is let's say I do FFT on a very large dataset or in an easier way to put it is a very heavy maths calculation and it also deals with graphics. So I'm not sure about how exactly can I do that comparison as I don't know Rust yet.

Hence, I wanted some guidance on which language to choose. Please ask additional questions if you need clearance as I'm not sure in myself how exactly to describe my issue.

Answer 1

depending on what operations you intend to use, Rust might be or not be what you want.

Being younger than C++, it does not have the large ecosystem of the latter.

searching for "Rust fft and graphics" gave me this link

Answer 2

C++ cuz I think it has more use cases 🤔(I could be very wrong)

Answer 3

Snehil Pandey, From what I have researched, I have come to the following conclusion:
• The best performance of Rust and C++ is almost identical, as both can generate equally optimal assembly if, and only if, the programmer writes efficient code and the compiler optimises well.
• However, C++ is much older than Rust and has years of appropriately tuned libraries, compilers ( like GCC or Clang) and industry use and shows excellent performance for mature domains like FFT, graphics, and linear algebra, because the best(?) implementations are pre-existent (e.g., FFTW, Intel MKL, CUDA etc. libraries).
• Rust, on the other hand, is newer as compaired to C++ and lacks the same highly optimised libraries for domains like heavy numerical computing or GPU programming.
• Rust is said to be more safe and reliable although C++ gives better and more complete control.

Answer 4

Ushasi Bhattacharya the very first answer I find it very much influencing.

As what I need as a whole is fast processing, secure practices to be there in my case

But still I believed regardless of online articles that c++ is superior

Thanks for your information and about debugging and stuffs I do acknowledge that c++ is hard but not to that extent.

I still have a vast topics to explore on c++ but based on my requirement I guess that I have some knowledge

But the issue here isn't about knowledge rather a secure code with fast processing

And yeah I'm greatly convinced to use c++ cause I find Rust a bit weird to learn (I mean it's quite difficult for me who started with cpp, c or java; same happened in python at the start)

Thanks for your detailed answer

Answer 5

Bob_Li thanks for your answer

And after understanding the video it seems a bit related to what I'll be performing
But the thing is can it be performed on c++ as easily as it done on rust cause I've not image processing knowledge on c++

Thanks for your answer I'll do the next part on my own.
Now I think I've got a clear point of what stuffs are needed

Answer 6

I think CPP i don't know Rust can be good but i like CPP there are so many reasons for this and already Ushasi write there all those things

Answer 7

C++

Answer 8

Abdi Biya , Semedo Junior, thank you, for answering this and showing such activeness towards the community!
However, this thread has alreen closed, as mentioned in the question by Snehil Pandey.
Hence, you need not post further answers here, as most of us are no longer following this thread. Considering that others might find it useful, a better alternative can be upvoting related answers in order to express your agreement.
Thank you.

Answer 9

Snehil Pandey
Also, as Bob_Li said, C++ has a vast ecosystem for numerics (FFTW, BLAS, LAPACK, CUDA, OpenCL, SYCL), graphics (OpenGL, Vulkan, DirectX wrappers, Unreal/Unity engines), and scientific computing which are optimised, and ready-to-use. These have still not been outperformed by Rust.

I should say that, if performance is the absolute top priority, you might want to use C++. And, if safety and maintainability is what ypu want, then Rust will probably be what you need.
Thank you.

Answer 10

Adding this as an after-thought:
C++ is a bit more difficult to master as compared to Rust. And to yeild the best performance using C++, one has to code very carefully making sure no bugs remain (C++ is also a bit difficult to debug).

Answer 11

C++

Answer 12

A rust course in sololearn would be nice.
