The Rust Programming Language ((NEW))



Rust is a powerful programming language, often used for systems programming where performance and correctness are high priorities. If you are new to Rust and want to learn more, The Rust Programming Language online book is a great place to start. This topic goes into detail about setting up and using Rust within Visual Studio Code, with the rust-analyzer extension.




The Rust Programming Language



Note: There is also another popular Rust extension in the VS Code Marketplace (extension ID: rust-lang.rust) but this extension is deprecated and rust-analyzer is the recommended VS Code Rust extension by rust-lang.org.


First you will need to have the Rust toolset installed on your machine. Rust is installed via the rustup installer, which supports installation on Windows, macOS, and Linux. Follow the rustup installation guidance for your platform, taking care to install any extra tools required to build and run Rust programs.


When you install Rust, you also get the full Rust documentation set locally installed on your machine, which you can review by typing rustup doc. The Rust documentation, including The Rust Programming Language and The Cargo Book, will open in your local browser so you can continue your Rust journey while offline.


When you install Rust with rustup, the toolset includes the rustc compiler, the rustfmt source code formatter, and the clippy Rust linter. You also get Cargo, the Rust package manager, to help download Rust dependencies and build and run Rust programs. You'll find that you end up using cargo for just about everything when working with Rust.


Note: Enable Workspace Trust for the new folder as you are the author. You can enable Workspace Trust for your entire project folder parent to avoid being prompted when you create new projects by checking the option to Trust the authors of all the files in parent folder 'my_projects`.


When you first open a Rust project, you can watch rust-analyzer's progress in the lower left of the Status bar. You want to wait until rust-analyzer has completely reviewed your project to get the full power of the language server.


rust-analyzer is able to use semantic syntax highlighting and styling due to its rich understanding of a project source code. For example, you may have noticed that mutable variables are underlined in the editor.


The rustc linter, enabled by default, detects basic Rust errors, but you can use clippy to get more lints. To enable clippy integration in rust-analyzer, change the Rust-analyzer > Check: Command (rust-analyzer.check.command) setting to clippy instead of the default check. The rust-analyzer extension will now run cargo clippy when you save a file and display clippy warnings and errors directly in the editor and Problems view.


Due to rust-analyzer's semantic understanding of your source code, it can also provide smart renames, across your Rust files. With your cursor on a variable, select Rename Symbol from the context menu, Command Palette, or via F2.


This has been a brief overview showing the rust-analyzer extension features within VS Code. For more information, see the details provided in the Rust Analyzer extension User Manual, including how to tune specific VS Code editor configurations.


To stay up to date on the latest features/bug fixes for the rust-analyzer extension, see the CHANGELOG. You can also try out new features and fixes by installing the rust-analyzer Pre-Release Version available in the Extensions view Install dropdown.


The Rust programming language has been quietly taking the tech world by storm, but adoption has been slower among game studios. Treyarch has been gradually integrating Rust into our tools and pipeline since 2018. This session leverages that experience to explore both the opportunities and challenges that Rust can give to the game tools programmer and examine the ways in which Rust can be a powerful addition to the tools arsenal.


The Rust programming language first debuted in 2010. Despite its relative youth, however, the language has quickly gained in popularity, offering a combination of performance and features that make it an appealing alternative to traditional options.


In terms of syntax, Rust is similar to C and C++, incorporating many of the keywords and commands from both languages. It is not a direct clone, however, and has some elements not found in either C or C++.


Today we are very proud to announce the 1.0 release of Rust, a new programming language aiming to make it easier to build reliable, efficient systems. Rust combines low-level control over performance with high-level convenience and safety guarantees. Better yet, it achieves these goals without requiring a garbage collector or runtime, making it possible to use Rust libraries as a "drop-in replacement" for C. If you'd like to experiment with Rust, the "Getting Started" section of the Rust book is your best bet (if you prefer to use an e-reader, Pascal Hertleif maintains unofficial e-book versions as well).


While Rust is relatively new, it has obviously gained a strong following. In relation to the languages it is compared against, especially C and C++, Rust is easier to learn and safer to use for new programmers.


As a result, many programmers see it as a serious alternative to C and C++ in the realms where those languages have reigned supreme. In fact, Dave Herman, Co-founder of Mozilla Research, laid out some of those benefits in a blog post:


Will Rust replace C and C++? It is highly unlikely, if nothing else because of the vast amount of existing code already written in those venerable languages. At the same time, however, many programmers acknowledge that Rust has serious advantages to both, bringing modern concepts, performance and safety to the same low-level approach that C and C++ are known for.


The Rust programming language, which was released in 2015, became popular in a short time. Continuing to increase in popularity since the year it was released, Rust managed to become the most popular programming language on Stack Overflow, with 86% positive votes. In addition to the interest of the developers, businesses continue to post Rust Developer hirings and increase the salaries as well.


This strain, called RansomwareExx2 and belonging to the RansomwareExx group, was discovered in the last months of 2022. This string, which none of the VirusTotal results saw as malicious for two weeks after its first detection, once again showed how dangerous the strains written in a different language are.


So why the intense love of Rust programming language? To put it simply, Rust coding was created to solve problems present in other languages and if you can take the time to unlock its (admittedly difficult) secrets, you're rewarded with cleaner, faster, and most importantly, safer code. Rust code resolves pain points that you see in countless other programming languages with far fewer downsides. Utilizing Rust allows developers to decide when they no longer need memory at the time of compilation which creates more efficiency around memory usage.


Antony Saba, a senior security engineer with Strategic Security at GitLab, recently talked about Rust during a company-wide series of meetings (Contribute 2020). He speaks from experience as his last employer was a Rust-based company. "Okay, so what's Rust's promise?" Saba asked. "Rust's promise is that it should be easier, and everybody should be able to fearlessly write at a systems level and not have to worry about memory safety or thread safety, or at least worry about it in the way that is supported by the language and the tools."


The open source Rust community describes the language as fast, reliable and productive. "Hundreds of companies around the world are using Rust in production for fast, low-resource cross-platform solutions," the organization says. Firefox and DropBox are two well-known users of Rust today, and Mozilla (creator of Firefox) was the first original supporter of Rust.


Think of Rust as the answer to a data-rich problem that will likely need lots of computational cycles. Mozilla's Rust documentation specifically calls out the language as ideal for "game engines, operating systems, file systems, browser components and simulation engines for virtual reality." 041b061a72
