Parameter type may not live long enough

Question

I have a simple program where I am trying to implement a polymorphic account type:

enum AccountType {
    INVALID,
    TYPE1,
    TYPE2,
}

trait Account {
          


        

Answer 1

The compiler's suggestion actually works. If you write add_account as follows:

fn add_account(&mut self, account: A) {
    self.accounts.push(Box::new(account));
}

your code compiles. (Incidentally, you need &mut self, not &self here)
