Problem

Is it possible to make Visual Studio Code run cargo fmt on file save?

Install the extension rust-analyzer (the officially recommended vscode extension), and add the following to settings.json:

"[rust]": {
    "editor.defaultFormatter": "rust-lang.rust-analyzer",
    "editor.formatOnSave": true
}

"[rust]": {
    "editor.defaultFormatter": "rust-lang.rust-analyzer",
    "editor.formatOnSave": true
}
