How to use nightly rustfmt in vscode

editors and IDEs
1

I want to use nightly rustfmt in vscode with rust-analyzer.
What do I write in setting.json.

I don't use vscode often, so I don't know if this has changed. But a while back I put this in my settings.json, and I believe it worked back then:

"rust-analyzer.rustfmt.extraArgs": [
        "+nightly"
    ],

Can I use unstable-features with this setting ?

Yes, as long as you also configure them as described below.

https://rust-lang.github.io/rustfmt/?version=v1.8.0&search=

Each configuration option is either stable or unstable. Stable options can always be used, while unstable options are only available on a nightly toolchain and must be opted into. To enable unstable options, set unstable_features = true in rustfmt.toml or pass --unstable-features to rustfmt.
