Module db_key_mapper 

Structs

SpreadPrefixKeyMapper

A DatabaseKeyMapper tailored for databases which cannot tolerate long common prefixes among keys (for performance reasons). In other words, it spreads the keys “evenly” (i.e. pseudo-randomly) across the key space. For context: our use-case for this is the Jellyfish Merkle Tree.
