1 This error indicates that a pattern for a struct fails to specify a sub-pattern
2 for every one of the struct's fields. Ensure that each field from the struct's
3 definition is mentioned in the pattern, or use `..` to ignore unwanted fields.
13 let d = Dog { name: "Rusty".to_string(), age: 8 };
21 This is correct (explicit):
29 let d = Dog { name: "Rusty".to_string(), age: 8 };
32 Dog { name: ref n, age: x } => {}
35 // This is also correct (ignore unused fields).
37 Dog { age: x, .. } => {}
