How to set vscode Rust tabsize as 4?

Question

I add the following code in settings.json, but it doesn't work.

"[Rust]": {
    "tabSize": 4
}

Answer 1

Working json

"[rust]": {
  "editor.tabSize": 4

Easy way to navigate to language specific settings:

1. open any rust file (*.rs)
2. click in the bottom bar Rust
3. in pop up window select Configure 'Rust' language base settings...
