This could be\r\n\r\n```rust\r\npub enum OuterJoin<T> {\r\n    Left(T),\r\n    Right(T),\r\n    Both(T, T),\r\n}\r\n```\r\nwith the `Item` being `(A::Key, OuterJoin<A::Val>)`, but the spatial metaphor is possibly confusing. It may also make sense to rename the trait method and struct to `Union`."}}
