 * structs containing this to be `Send`. The only two ways to achieve that
 * are either storing a `dyn Trait` inside an `Arc<Mutex<&dyn Trait>>` or
 * making the type itself `Send`. We opted for not complicating the user nor
 * moving the guarantees to runtime by using an `enum` rather than a `Trait`.
 * This works under the assumption that we don't expect downstream users to
 * extend Cairo by adding new builtin runners.
