==== Live Share
VS Code Live Share has partial support for rust-analyzer.
Live Share _requires_ the official Microsoft build of VS Code, OSS builds will not work correctly.
The host's rust-analyzer instance will be shared with all guests joining the session.
The guests do not have to have the rust-analyzer extension installed for this to work.
If you are joining a Live Share session and _do_ have rust-analyzer installed locally, commands from the command palette will not work correctly since they will attempt to communicate with the local server.
