C and C++ are among the many most pervasive programming languages within the software program trade right this moment, with over 6.3 million builders utilizing the language to code nearly every little thing. Now, there may be one other language that has confirmed to be a worthy competitor to C and C++; Rust.
Developed by a Mozilla Analysis worker Grayson Hoare, Rust has grown into its personal over the previous 15 years of its existence. From being picked up by tech giants like AWS, Meta, and Atlassian to supporting Web3 ecosystems like Ethereum and Solana, Rust is rapidly turning into a celebrity within the improvement world.
Furthermore, the language has additionally been voted because the most-loved programming language in Stack Overflow’s Developer Survey for the previous seven years. However what makes this language so cherished and highly effective and does it have the aptitude to exchange C?
The grandchild of C
The language borrowed the most effective parts from a number of programming languages, such because the easy-to-use syntax of C and C++ together with the practical nature of languages like Haskell. This piecemeal strategy resulted in Rust collating lots of the developer’s beloved options whereas protecting a concentrate on quick execution and secure code.
Within the weblog submit asserting Rust’s 1.0 launch, the workforce mentioned, “[Rust’s] sort system. . . represents a refinement and codification of greatest practices which have been hammered out by generations of C and C++ programmers”.

Along with its heritage from different languages, Rust has sure game-changing options of its personal. As an example, Rust has granular entry to low-level code whereas additionally toeing the road between functionality and abstraction with its high-level capabilities. The language additionally boasts a strong optimiser and wields many zero-cost abstractions to chop down on runtime.
The language was constructed from the bottom as much as allow concurrent programming, a killer characteristic that makes it a must have within the HPC discipline. Rust can also be extraordinarily centered on pushing builders to create memory-safe code, because it doesn’t have in-built rubbish assortment.
The programme as a substitute encourages reminiscence borrowing and lending methods, together with clear-set guidelines for when a variable can be dropped from reminiscence. The concentrate on reminiscence security cuts down on the quantity of bugs within the last product, saving on time and assets in relation to deployment.
However, C and C++ undergo from characteristic creep introduced on by years of haphazard updates. These outdated languages additionally lack the options that the majority builders take with no consideration in fashionable languages, like straightforward integrations for libraries, environment friendly reminiscence administration methods and run-time checking. Reddit person Matthieum sums it up completely in a remark, stating,
“C++ is a large number. It’s nobody’s fault, actually, principally a historic accident, but it surely’s one thing you pay each day. There was not sufficient madness in C so the builders of C++ determined so as to add some extra. Did I speak about reminiscence security? Knowledge-races? No. There’s little level actually. To tame C++, one should gaze into the abyss.”
Rust’s lack of rubbish assortment not solely makes programmes run quicker, it additionally makes it a viable drop-in alternative for C. Furthermore, its nature as a language skirting the road between high-level and low-level makes it a very good match for purposes that already use C and C++.
Will C be relegated to the previous?
Rust has lots of the capabilities of C and C++, together with related syntax. Additional, because of the intrinsically secure nature of the language, even new builders can create advanced code with out worrying about application-breaking bugs. Along with this, Rust additionally comes with ‘Cargo’, a construct system and bundle supervisor, thereby making importing code straightforward.
Over the previous few years, tech giants have additionally made it some extent to combine Rust into a lot of their choices. AWS FireCracker VMM is constructed utterly on Rust, and lots of different companies like S3, EC2, CloudFront, and Route 53 all use Rust for deployment. The language has additionally been launched into the Linux Kernel whereas Azure has largely shifted to utilizing Rust over C citing safety considerations.
When wanting on the capabilities of Rust, it’s extremely doable that this language may develop into a stand-in for C within the close to future. The Rust neighborhood has additionally created assets to port C/C++ code to Rust, and one other member has created Corrode, a translation layer between C and Rust.
Nevertheless, as seen with legacy languages like Fortran and COBOL, the trade has a whole lot of inertia when transferring away from outdated techniques. On the final estimate, there are roughly 10 billion traces of C++ code in a manufacturing atmosphere. This suggests that there’s an equally robust pressure in opposition to switching to any language that’s not C++.
Nevertheless, with sufficient momentum behind Rust, it’d develop into the established order programming language of the longer term, with C and C++ being delegated to their rightful legacy place.
