Instead you should use rust-analyzer which will soon become the official rust extension.

What you really want is to install the rust-analyzer plugin, not the Rust plugin.
I find this comment very confusing. Neither plugin was developed by Microsoft.
The "rust" extension generally comes up first because it's older and has significantly more downloads. That being said, it's true that imho everyone should use the new one.
