error[E0594]: cannot assign to `self.how_hungry` which is behind a `&` reference
--> $DIR/mutable-class-fields-2.rs:9:5
|
LL | pub fn eat(&self) {
| ----- help: consider changing this to be a mutable reference: `&mut self`
LL | self.how_hungry -= 5;
| ^^^^^^^^^^^^^^^^^^^^ `self` is a `&` reference, so the data it refers to cannot be written
error: aborting due to previous error
