Can you also add a test case to exercise this, to ensure it doesn’t regress in
the future? meta/lib/oeqa/sdk/cases/rust.py has some minimal testing already
so adding more there would be great.

There’s another series on the list that rewrites this
(https://lore.kernel.org/openembedded-core/[email protected]/)
and moves some assignments to an environment file in rust.bb. I suspect the
same needs to happen here, so can you rebase on top of that patch (or wait for
that to be merged and rebase).
Thanks,
Ross
