10 * This type is an opaque union. Unions can't derive anything interesting like
11 * Debug or Default, even if their layout can, because it would require knowing
12 * which variant is in use. Opaque unions still end up as a `union` in the Rust
13 * bindings, but they just have one variant. Even so, can't derive. We should
14 * probably emit an opaque struct for opaque unions... but until then, we have
15 * this test to make sure that opaque unions don't derive and still compile.
