For Rust developers, CLion offers full cargo support. One major strength CLion has over Visual Studio is it is cross platform in nature, available on Windows, Mac and Linux. JetBrains CLion is heavily designed around CMake, using that CMakeLists.txt as the standard project format and integrating into open tools such as clang, clang-tidy and GDB/LLDB. It is built on the same core as IntelliJ and thus shares a very similar user interface, hundreds of extensions and most of the strengths and weaknesses of that platform. While the recently released Fleet is aimed at Visual Studio Code, CLion is aimed more at the full version of Visual Studio, or more specifically Visual C++. It frequently highlights patterns that could be better replaced with more idiomatic or performant Rust.CLion is an IDE from JetBrains, the makers of IntelliJ IDEA, Rider, Fleet, WebStorm and several other programming tools. I found clippy indispensible when learning Rust. Keep in mind that this takes additional resources and can be a bit slower, but it’s worth it. You can run cargo clippy yourself or set rust-analyzer to run clippy on save to get loads of additional warnings and lints. Get clippy via rustup component add clippy (you may notice you have it already). Clippy is like the ESlint of the Rust universe. If you want more, then you’re looking for clippy. cargo check essentially just compiles your project looking for errors. Additional lintingīy default, rust-analyzer runs cargo check on save to gather project errors and warnings. The UI is a great way to explore settings, while JSON is more convenient for rapid editing and sharing. See the VS Code documentation for more info. You can edit your settings via a UI or as JSON by opening the command palette with Ctrl+Shift+P, typing settings and selecting which you want. We’ll get into the module system a couple posts after we start working with code, but you can alleviate this now by including your module via a line like mod my_module. That is to say, files can’t get checked unless they are imported all the way down to a root source file (e.g. That’s because Rust projects (‘crates’) rely on a formal structure stemming from the root. They do complain about incorrect syntax, but they don’t autocomplete anything and don’t issue warnings about obviously incorrect code. my_module.rs, you’ll notice that VS Code & rust-analyzer do something but seem to be broken. If you create a new file in a Rust project, e.g. rs file and expect full IDE functionality, which brings us to… If things don’t feel like they’re working… Note: you must be in a properly structured Rust project for rust-analyzer to work. Once you’re installed and rust-analyzer has downloaded everything it needs, you should be good to go. To install rust-analyzer, search for it in the extensions pane or press Ctrl+Shift+P then enter: If you are exploring both, make sure you disable one to get a fair view of the other. The rust ( st) and rust-analyzer ( st-analyzer) plugins don’t work well together. Rust-analyzer has been great from day one. They promise similar features but I could never get the rust plugin to work reliably. There are two primary plugins, rust ( st) and rust-analyzer ( st-analyzer). Day 21: Building and Running WebAssembly.Day 16: Lifetimes, references, and 'static.Day 9: Language Part 3: Class Methods for Rust Structs (+ enums!).Day 8: Language Part 2: From objects and classes to HashMaps and structs.Day 4: Hello World (and your first two WTFs).If anything doesn’t work exactly as is for your environment, send questions or comments to me on Twitter or join our Discord. jump to definition, implementation, type, et al.The most important pieces are there with features like: You won’t find the breadth of plugins with Rust as you do with JavaScript, but it’s growing rapidly. If you haven’t yet given it a shot, you should. Visual Studio Code dominated the JavaScript ecosystem almost on arrival.
