Rust Development Environment Installation Notes

Installing LSP

LSP (Language Server Protocol) is a new generation tool for browsing source code. For Rust, rust-analyzer is the recommended LSP.

git clone https://github.com/rust-analyzer/rust-analyzer.git
cd rust-analyzer
cargo xtask install

VScode

After installing VSCode, you also need to install rust-analyzer. Once installed, VSCode works out of the box.

STM32CubeIDE

STM32CubeIDE is Eclipse-based, so you only need to install the Rust plugin.

Rust Plugin

A relatively new version of the Rust plugin must be installed, otherwise it cannot support rust-analyzer.

• Menu: "Help" -> "Install New Software..." -> "Add..."
• Repository: http://mirrors.ustc.edu.cn/eclipse/corrosion/releases/1.2.3/
• Plugin: Corrosion: Rust edition in Eclipse IDE

Rust Settings

Click Window -> Rust to check whether the paths for rustup, cargo, rust-analyzer, etc., are correct.

Debugging

Just like debugging C code, you can set breakpoints in Rust code using STLink within STM32CubeIDE.

Known Issues

• [2023-04-25] Higher versions of STM32CubeIDE (>=1.9.0) fail to launch the plugin after successful installation.
  • Solution: Do not install the latest (1.2.4) version of the Rust plugin. Install the 1.2.3 plugin instead.
