How can I get Visual Studio Code to reset the IntelliSense engine for Rust?

Question

I am working on two projects, one is a library, the other is a program that uses that library. When I make changes to the library the other window (the program) doesn't see these changes, so I do not get updated IntelliSense. Closing the program that uses the library and reopening it does force an update but I really prefer not having to go that far.

Answering the title directly and not the root issue...

You can reset IntelliSense and all Rust code features by running the "Rust: Restart the Rust server" command from the command palette (Ctrl+Shift+P).

Progress will be indicated in the status bar.

Still a blunt tool but it will ensure you're in a fresh state without having to restart VS Code entirely.
