The former code is more equivalent to:

  let file = match file {
    Some(file) => file,
    None => panic!("file was null");
  };

Which you'd never write in practice since `expect` exists

Can you say more here, I don't have the context.

This code is identical to

  let file = file.expect("file was null");

That is, the "expect" method does exactly this.
