Types ¶
type CacheKVStore ¶
type CacheKVStore interface { KVStore // Writes operations to underlying KVStore Write() }
CacheKVStore branches a KVStore and provides read cache functionality. After calling .Write() on the CacheKVStore, all previously created CacheKVStores on the object expire.

type CacheMultiStore interface { MultiStore Write() // Writes operations to underlying KVStore }

func (*StoreInfo) GetCommitId ¶ added in v0.40.0
func (StoreInfo) GetHash ¶ added in v0.40.0
GetHash returns the GetHash from the CommitID. This is used in CommitInfo.Hash()
When we commit to this in a merkle proof, we create a map of storeInfo.Name -> storeInfo.GetHash() and build a merkle proof from that. This is then chained with the substore proof, so we prove the root hash from the substore before this and need to pass that (unmodified) as the leaf value of the multistore proof.
