how to display constants as it's name for rust.

[cathaysia]

I have a field in my struct that may be a constant. for example:

struct Age(i32);
impl Age {
   const ZERO: Age = Age(0);
   const INVALID: Age = Age(-1);
   pub fn new(age: i32) -> Self {
      Self(age)
  }
}

struct Person {
   age: Age
}

let baby = Person {
  age: Age::ZERO
};
let tom = Person {
  age: Age::new(10)
}

While debugging I see that the age field of baby is 0. And tom's age is 10. Is there some way to format baby age field as Age::ZERO
