Opened a separate CI-fix PR here: https://github.com/eclipse-uprotocol/up-transport-vsomeip-rust/pull/43\n\nThis isolates the main CI failures (plus feasible warning cleanups encountered while validating) from #42. The failures are reproducible from and are validated in that independent branch with local clippy/test runs.

Correction: the failures referenced above are reproducible from the upstream main branch.

Clean cross-link: independent CI-fix PR is #43.
The failures addressed there are reproducible from upstream main.

Opened follow-up PR: #44

This carries the same functional change from PR #42 on a clean branch scoped to up-transport-vsomeip/src/determine_message_type.rs, and preserves original author credit via git cherry-pick -x.

Update on follow-up PR #44:

To satisfy current Eclipse Contributor Agreement email checks, the follow-up branch was force-updated to use maintainer commit authorship. Functional scope remains unchanged and still carries the same source patch from this PR.

For the sake of expediency, I fixed this here:
#44

I tried to add you to that PR's commit but it didn't seem to like it for ECA reasons :(

Therefore, closing this one.
