/// email: String,
/// }
///
/// impl WithEmail for Contact {
/// fn email(&self) -> &str {
/// &self.email
/// }
///
/// fn set_email(&mut self, email: &str) {
/// self.email = email.to_string();
/// }
/// }
///
/// let mut contact = Contact {
/// name: "Alice".to_string(),
/// email: "alice@example.com".to_string(),
/// };
/// assert_eq!(contact.email(), "alice@example.com");
