Workspace mode not working with "plietar/librespot"

[Hoeze]

Hi,
I tried using the workspace mode of vscode Insider with following project:
https://github.com/plietar/librespot/

However, it does not seem like vscode watches the sub-projects in this folder.
There are no recommendations when typing "librespot::audio::" + <ctrl> + <space>.

My settings:

{
    "rust.workspace_mode": true,
    "rust.unstable_features": true
}

I am using an up-to-date rust nightly tool chain.

We've not tried to integrate with VSCode's workspace more, so I wouldn't expect this to work. However, it is something I would like to get working in the future.
