Sorry for the inconvenience. For context, the current Debian rust situation is a workaround for dpkg bug #901827. In general though, arbitrary buffer sizes should be a thing of the past. Have you considered rewriting that code in Rust? :) Or perhaps less effort, just reusing whatever code dpkg itself uses to parse it.
