Fields

db: &'a dyn HashDBRef<KeccakHasher, Vec<u8>>

database to query from.

query: Q

Query object to record nodes and transform data.

hash: [u8; 32]

Hash to start at

cache: Option<&'cache mut dyn TrieCache<ReferenceNodeCodec<KeccakHasher>>>

Optional cache that should be used to speed up the lookup.

recorder: Option<&'cache mut dyn TrieRecorder<[u8; 32]>>

Optional recorder that will be called to record all trie accesses.
