As the error message suggests, the problem is JobsList has a private field, that is, the Vec<Job> value is inaccessible outside the module that defines the struct. This means that you cannot pattern match on a JobsList value to extract it, and that you cannot construct it directly.

There's two fixes:

• make the field public pub struct JobsList(pub Vec<Job>);

• provide a public constructor

  impl JobsList {
      pub fn new(jobs: Vec<Job>) -> JobsList {
          JobsList(jobs)
      }
  }
  

  called like JobsList::new(vec![]).
