This PR adds
merkledb.View
to themerkledb.MerkleDB
interface. This adds the already implementedCommitToDB
function to the exported interface.Downstream code (HyperSDK) uses
merkledb.View
type to represent the view calculated for an individual block. After committing a view, that view is no longer safe to use and the last committed state is represented directly by theMerkleDB
instance. However, this complicates using the existing interface for the "view" of the last accepted block sinceCommitToDB
is not implemented.
