Markus Westerlind 0e01067d55 feat: Allow queries to avoid panics on cycles ... Quickest POC I could create to get some potentially cyclic queries to not panic and instead return a result I could act on. (gluon's module importing need to error on cycles). ``` // Causes `db.query()` to actually return `Result<V, CycleError>` fn query(&self, key: K, key2: K2) -> V; ``` A proper implementation of this would likely return `Result<V, CycleError<(K, K2)>>` or maybe larger changes are needed. cc #6		2019-08-16 20:37:54 +02:00
