Debugging Rust Code in Visual Studio Code

Setting up Rust on Your Computer

To get started with debugging Rust code, you need to have Rust installed on your computer. Follow these steps:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

(for macOS or Linux) or download the installer from the official Rust website (for Windows).

If you’re using Windows, don’t forget to install the build tools.

Verify that Rust has been installed correctly by opening a command window or terminal and typing:

rustc --version

Creating a New Rust Project

To create a new Rust project, follow these steps:

1. Open a command window or terminal and navigate to the directory where you’d like to create your project.
2. Use the command cargo new myproject to create a new Rust project called “myproject”.
3. Change directories into your new project using cd myproject.
4. Open VS Code in the current directory using code...

Setting up VS Code for Debugging Rust

To set up VS Code for debugging Rust, follow these steps:

1. Install the rust-analyzer extension in VS Code.
2. Open the Command Palette in VS Code using Ctrl+Shift+P (Windows/Linux) or Cmd+Shift+P (macOS).
3. Type “Rust: Select Toolchain” in the Command Palette and select the toolchain that matches your Rust installation.
4. Create a new launch configuration in VS Code by going to Run > Add Configuration… and selecting “Rust”.
5. Modify the launch configuration to suit your needs.

Debugging Rust Code

To debug your Rust code, follow these steps:

1. Open the Rust file you want to debug in VS Code.
2. Set breakpoints in the code by clicking in the left margin next to the line numbers.
3. Start debugging by pressing F5 or by clicking on the “Run” button in the top menu.
4. VS Code will stop execution at the first breakpoint it encounters.
5. You can inspect variables, expressions, and registers using the Debug panel.

Popular Extensions for Rust Development in VS Code

Here are some popular extensions for Rust development in VS Code:
