Install rust-analyzer Extension in Codium

VSCodium is a free/libre open-source version of Visual Studio Code (VS Code). Unlike the official VS Code, VSCodium does not include any proprietary telemetry or Microsoft branding, making it a privacy-friendly alternative. You can download it from: https://vscodium.com/

To manually install Rust Analyzer for VSCodium, you need the VSIX package file, which is the extension’s installation file for VS Code-compatible editors. The current download link for Rust Analyzer is this one.

https://rust-lang.gallery.vsassets.io/_apis/public/gallery/publisher/rust-lang/extension/rust-analyzer/0.4.2602/assetbyname/Microsoft.VisualStudio.Services.VSIXPackage

This URL is constructed based on the method explained here, which shows how to fetch the direct VSIX download link for any VS Code extension.

The version of Rust Analyzer in this link comes from the official Visual Studio Marketplace page for the extension: https://marketplace.visualstudio.com/items?itemName=rust-lang.rust-analyzer

Key points for constructing the link:

  • Publisher: rust-lang
  • Extension name: rust-analyzer
  • Version: 0.4.2602 (current as of this link)

Important Note

When downloading the file from the constructed URL, it will have the extension .VSIXPackage. For VSCodium to recognize it as an installable extension, you must rename the file to use a lowercase .vsix extension (case-sensitive).

After renaming, you can install the extension in VSCodium via “Extensions → Install from VSIX…”.
