Normally, the plugin update should go seamlessly. In case of any issues, try refreshing the project (click Refresh in the Cargo tool window) or rebuilding indices ( File | Invalidate caches / Restart from the main menu).
Previous versions of the plugin are available at the JetBrains plugin repo.
To make sure your toolchain is set up correctly,
Settings / Preferences | Languages & Frameworks | Rust and check the
Standard library paths.
Cargo project structure
Currently, the plugin supports only the Cargo-based Rust projects.
Check the Cargo tool window to make sure your project is imported properly. To force the project structure update, click Refresh in the Cargo tool window
(or call Refresh Cargo project using
Help | Find Action).
You should see a notification about the successful update.
If your code includes macros or you experience problems with name resolve, highlighting, or some analysis features (especially related to methods of primitive types),
try switching to the experimental macro expansion engine in
Settings / Preferences | Languages & Frameworks | Rust,
Expand declarative macros.
