New codespaces will have Rust & Cargo installed.

Awesome, thanks! How do you use that, just change github.com to github.dev?

[seishun]

Apparently you can create a codespace through github.dev but this is a more direct way: https://docs.github.com/en/codespaces/developing-in-a-codespace/creating-a-codespace-for-a-repository
