# We need to clean in the Rust dir, as in some cases the Serde/CXX derive/generate code does not get
# re-run by cargo after rust/src/lib.rs changed because of a generate.py run. In that case we end up
# with an rust/src/lib.rs.h that does not contain e.g. field name or field type changes. This
# cleanup is now done from generate.py itself.
#
# Use patterns to avoid having two instances of generate run simultaneously, a well-known hack for GNU make
