Cargo metadata omits workspace package ids: {missing_ids}

Error message

Cargo metadata omits workspace package ids: {missing_ids}

What it means

Some ids listed in workspace_members have no matching entry (by 'id') in the packages array. The member list and the package records are therefore inconsistent, and the validator cannot resolve those members; the message lists the offending member ids.

Solutions

1. Regenerate the fixture in one shot from the same workspace state so members and packages agree
2. Or edit workspace_members to remove the ids you deleted from packages

def members_resolvable(metadata: dict) -> bool:
    members = metadata.get("workspace_members", [])
    ids = {p.get("id") for p in metadata.get("packages", []) if isinstance(p, dict)}
    return all(m in ids for m in members)

When it happens

Trigger: A fixture whose packages array was trimmed while workspace_members still references the removed entries; mixing outputs captured from two different workspace states.

Common situations: Curating cargo-metadata fixtures for unit tests and deleting package entries without updating the member list.
