Doing this will result in a partial move of the variable, which means that parts of the variable will be moved while other parts stay. In such a case, the parent variable cannot be used afterwards as a whole, however the parts that are only referenced (and not moved) can still be used. -```rust,editable +```rust // fix errors to make it work #[derive(Debug)] @@ -56,7 +66,7 @@ fn main() { // ONLY modify this line println!("{}, {}, {:?}",f.name, f.data, f); -} +} ``` 🌟🌟 A match guard is an additional if condition specified after the pattern in a match arm that must also match, along with the pattern matching, for that arm to be chosen.
