![]() To do so, you can wrap it in higher-level abstractions which guarantee that all uses of the abstraction are safe. The unsafe Rust mode unlocks more options, but you need to take extra care to ensure that your code is truly safe. it can operate on raw C-like pointers), but the code may break. Unsafe Rust gives the programmer more autonomy (e.g. object ownership management), thereby ensuring that the code works properly. Safe Rust imposes additional restrictions on the programmer (e.g. In Rust there are two modes of writing code: Safe Rust and Unsafe Rust. The same number is also reported for Google Chrome. The importance of correct memory management becomes immediately apparent when you realize that over the past 12 years around 70% of all security bugs in Microsoft products have been memory safety issues. This feature solves the problem with references that are no longer valid, and also distinguishes Rust from C and C++. Such problems are detected at the compile time, and garbage collection is unnecessary.Īdditionally, in Rust, each reference has a lifetime, where you can set the scope for which that reference is valid. This feature helps you eliminate memory violation bugs. In Rust, on the other hand, you have the borrow checker-the part of the compiler that ensures that references do not outlive the data to which they refer. calling the lambda function after freeing its reference captured objects. One of them is ‘use after free errors,’ which happen when a program continues to use a pointer after it has been freed, e.g. ![]() by implementing smart pointers), but many problems remain unresolved. Of course, one can argue that modern C++ is putting greater emphasis on memory safety (e.g. However, these are not the only examples of how Rust is different from C++. Rust solves problems that C/C++ developers have been struggling with for a long time: memory errors and concurrent programming. In 2021, the Rust Foundation has taken the torch and is driving the development of the language. It is an open-source project developed originally at Mozilla Research. Rust is a statically-typed programming language designed for performance and safety, especially safe concurrency and memory management. But is it just another hype technology that promises a lot, but will soon vanish? What is so special about Rust language? Microsoft, meanwhile, has turned to Rust to reduce memory-related bugs in Windows components.įacebook has also forged closer ties with Rust, joining the Rust Foundation, an organization created in 2021 to drive the development of Rust and make it “a mainstream language of choice for systems programming and beyond.” Facebook joins Amazon Web Services, Google, Huawei, Microsoft, and Mozilla in using Rust in some capacity.Īll these are clear signs that Rust has been gaining traction in the past few years. The entire operation is aimed at reducing security flaws. Moreover, Google is also planning to use Rust in the Linux kernel after bringing support for the systems programming language Rust to Android. This idea is in continuous development - at this moment, it is still described as experimental, but “good enough that kernel developers can start working on Rust abstractions for subsystems and write drivers and other modules.” No less a figure than Linus Thorvalds, the father of the open-source operating system Linux, welcomed the idea and is keen to see the project results. To be clear, they did not want to rewrite the entire Kernel, which was originally written in C, but to add new code in Rust that would work with the existing infrastructure. In 2020, Linux kernel developers proposed writing new Linux kernel code in Rust. And it won the title for the seventh year running. ![]() Rust’s growing popularityĪccording to the Stack Overflow Developer Survey 2022 conducted among over 80,000 developers, Rust is the most beloved programming language. In this article, you can find more about Rust’s main characteristics, what it is used for, and why you should consider adopting it for your software projects. ![]() Firefox, Dropbox, Cloudflare, and many other companies from startups to large corporations use Rust in production. High performance while processing large amounts of data, support for concurrent programming, and this together with an effective compiler are other reasons why well-known software heavyweights now use this programming language. However, Rust has more than just memory safety on its side. Rust was created to ensure high performance similar to that offered by C and C++, but with emphasis on code safety, the lack of which is the Achilles heel of these two languages. ![]()
