Is sthere a way to retrieve the hash for an ID from a store? #3

Hello, apologies if this is not the best way to reach out, was just wondering if there is a suggested way to retrieve a Hash that had been added to a Store.

The use case is for comparing images in 2 separate directories. I hope to create a store of all images in dir1 as store1 and images in dir2 as store2. The stores are then compared by iterating over all the IDs of one store1 , retrieving the Hash for an ID and Querying it against store2. And then doing it the other way around. Hope this makes sense. Any input is greatly appreciated.

Currently, there isn't such a function. The hashes are not saved directly in the store, at least not in one piece. Each part of the hash determines the search path in the tree. I suppose one could re-engineer the hash from that search path but it would be difficult.

I would suggest that when you generate the stores, you also save the hashes in a separate map for later.
