--features in workspace note not actionable

[pickfire]

Describe the problem you are trying to solve

I am trying to use --features for one of the package in workspace but the reported error is not actionable.

error: --features is not allowed in the root of a virtual workspace
note: while this was previously accepted, it didn't actually do anything

Describe the solution you'd like

I haven't check how yet but the features, I guess one needs to search through github issue or stackoverflow to figure this.

Notes

Aside, the note text should be bold, rustc does but cargo does not.

The --features flag only works in a package directory.

On nightly, you can use the -Z package-features flag to use it in a workspace.

Yeah, but what should an average joe do on stable? Do they need to edit the Cargo.toml in the package?

[ehuss]

You can cd into the package directory.

[pickfire]

Maybe we can add that as a suggestion?

Yea, feel free to submit a PR! Better error messages are always welcome.

I feel it's also worth mentioning the --manifest-path since it doesn't require changing the current dir, AIUI it also respects the rules around workspaces/parent manifests and such.
