Function run 

pub fn run(
    account: &Account,
    password: &str,
    jobs: &[Job],
    claim: bool,
) -> Result<Done, SyncError>

The plans done on account’s inbox, in one session: with claim, each message marked first, and left alone when another device marked it, it was read meanwhile or it left the inbox (after a fetch); without, every job, as you asked (the whole inbox). The copies here follow.
