Rust vs C++: The Key Differences You Should Know

Author: Call Tutors

The Rust and C++ programming languages are critical in IoT development because they are both used in areas where direct hardware configuration, performance, and low-level access to memory and controllers are critical. IoT device and application levels, system programming (drivers, operating system kernels, controllers, and so on), desktop utility programming, 3D game creation, and a variety of other sectors are just a few examples. Rust vs C++, both programming languages, have seen a significant increase in market demand over time. Rust is a versatile language with memory safety, whereas C++ is an object-oriented programming language.

What is the Rust programming language?

Rust was created in 2010 as a child of Mozilla, but it is now an independent organisation with its own foundation. The robust and safe concurrent capabilities of this multi-paradigm, high-level, general-purpose programming language are well-known. Although the syntax of Rust and C++ are very similar, Rust provides a better level of memory safety without the use of a garbage collector.

What is the C++ programming language?

It's described as a compiled high-level, general-purpose language. C++ is frequently used to create programmes that demand a lot of speed and concurrency. Although it should go without saying, C++ is an extension of the C programming language, and it is sometimes referred to as "C plus classes".

When can you use Rust or C++?

Each of the examples below will work in both C++ vs Rust (at least in theory). There is no technical reason why one of these programming languages should be excluded from a project that requires the same compilation mode and features that affect performance. As a result, if you can use C or C++, Rust should work as well. Of course, one of them will be a better option in some circumstances than the other.

These programming languages are frequently used for the following purposes:

  • Kernel driver development, software running on restricted devices/firmware (also known as embedded devices)—what's crucial is that Rust is regarded as an official language for Linux kernel development.

  • Backend—the Go programming language was prominent in this industry, but Rust is attempting to steal Golang's place—e.g., Dropbox utilised Rust to update its sync engine core, game development—for the time being.

  • C++ is still the leading language in this field. Although Rust may not have as many frameworks as C++, its developers are always working to improve it, so don't overlook it.

Rust and C++:The key difference you should know

There are many parallels between these two programming languages. However, there is one element that unites them: safety. Rust is more secure than C++ since any potential error results in code rejection. Rust has a "safe-by-default" policy. It strikes a compromise between avoiding undesired behaviours and enabling them provided the cost is not too high. In C++, an error could slip through the cracks, resulting in application crashes or even security flaws.

"In C, you only publish your API if it can be used appropriately" (open world). If it's impossible to use wrongly (closed world), you provide a safe API in Rust." This quotation clearly demonstrates the differences between these two programming languages (it relates to the C programming language, but there is no difference in this situation between C++ and C).

Community

Every language has a community that is concerned in language development, keeping libraries up to date, and proposing changes. Simply said, the community contributes to the advancement of the language. What are the differences between the Rust and C++ communities?

Both programming languages may brag about their vibrant communities. Both the Rust vs Cpp communities are welcoming and active. Whatever the problem, you'll quickly find a slew of forums full of individuals willing to assist. You don't have to take our word for it; check out the Rust Community and C++ pages for more information.

Tooling in Rust and C++

Creating, debugging, maintaining, and supporting programmes and apps should be made easier with the right tools. Is there a similarity in the answers provided by these programming languages? Let's see how they compare.

Rust provides easy-to-use tooling right out of the box. Cargo is a single standardised tool for building, generating distributable packages and submitting them to crates.io for Rust's package dependencies. Because of this, every Rust code repository appears to be the same—you won't be shocked by the dependencies, repository structure, when the tests are run, or anything else. On the other side, everything in the C++ repository looks different, and you have to learn it from start each time.

Conclusion

Both Rust vs C++ have strong performance, tooling, and community support, making them potentially ideal candidates for your next project. There is no clear winner, but when it comes to programming languages, there is never a one-size-fits-all solution. We recommend that you brush up on your Rust knowledge if you haven't already.
