+// For each enum declared in the UDL, we assume the caller has provided a corresponding
+// rust `enum`. We provide the traits for sending it across the FFI, which will fail to
+// compile if the provided struct has a different shape to the one declared in the UDL.
+//
+// We define a unit-struct to implement the trait to sidestep Rust's orphan rule (ADR-0006). It's
+// public so other crates can refer to it via an `[External='crate'] typedef`
