+description: |
+  Using .expect() in Rust can lead to unexpected panics if the value is None (for Option) or Err (for Result).
+  While expect() provides a custom error message, uncaught panics in production can crash the application.
+  Consider handling errors explicitly using match or if let, providing defaults with unwrap_or_else(),
+  or propagating errors using the ? operator.
