I'm looking at ways to integrate an external cache (or really any cache where the storage/retrieval requires some sort of serialization traits--e.g., serde, bitcode, rkyv, etc.) for DataLoader, but am having trouble with the bounds for the CacheStorage trait.

Redis cache for dataloaders is one route I'm attempting to implement.

I've been fiddling with attempts at specialization to have alternate implementation if the Key, Value types have implemented certain traits, but not having any luck there.

Maybe I'm missing something, but is it possible to implement custom caching for DataLoader which requires serialization? If anyone has an example, that would be much appreciated.

Thanks in advance!
