public final ComputeThreatListDiffResponse computeThreatListDiff(
      ComputeThreatListDiffRequest request) {
    return computeThreatListDiffCallable().call(request);
  }
Gets the most recent threat list diffs. These diffs should be applied to a local database of
hashes to keep it up-to-date. If the local database is empty or excessively out-of-date, a
complete snapshot of the database will be returned. This Method only updates a single
ThreatList at a time. To update multiple ThreatList databases, this method needs to be called
once for each list.
