Function run 

pub(crate) fn run(
    job: Job,
    events: &Receiver<Event>,
    connect: Sender<Event>,
    report: &impl Fn(Report) -> Result<(), Abandoned>,
) -> Result<(), Abandoned>

Runs job, handling events until it ends, and sending each step to report. connect is where its connections send their events.

Errors

Abandoned once the app is gone, which stops the download early.
