Function pull 

pub fn pull(
    memory: &Path,
    folder: &Path,
    own: &str,
    login: &Login,
    now: i64,
) -> Pulled

The other devices’ files newer on the server than here, fetched beside the synced folder (see the module’s words); own is this device’s id, whose files are never fetched. Nothing when the folder is not confirmed, or its seal here is no longer the one fetched under. Never on the window’s thread.
