Variable lifetime visualization for borrow checker errors

RustRover can visualize variable lifetimes in case the borrow checker reports an error. This may help you in locating and fixing ownership issues.

note

For this feature to work, make sure on-the-fly linter analysis is turned on: you can do it using the widget in the status bar.

Also, the Inline explanations setting must be enabled in Settings | Editor | Inlay hints | Other | Rust (it is enabled by default).

Place the caret at the highlighted code or hover over it – the variable lifetime will be marked with a vertical blue line on the left and a pair of comments on the right.
