Module merklized_state

Api for querying merklized state

The state API provides an interface for serving queries against arbitrarily old snapshots of the state. This allows a full Merkle tree to be reconstructed from storage. If any parent state is missing then the partial snapshot can not be queried.

Traits

MerklizedState

This trait should be implemented by the MerkleTree that the module is initialized for. It defines methods utilized by the module.

MerklizedStateDataSource

This trait defines methods that a data source should implement It enables retrieval of the membership path for a leaf node, which can be used to reconstruct the Merkle tree state.

MerklizedStateHeightPersistence

UpdateStateData

This trait defines methods for updating the storage with the merkle tree state.
