&self,
hash: Option<Hash>
) -> impl Future<Item = Bytes, Error = RpcError>

block: Hash,
hash: Option<Hash>
) -> impl Future<Item = Vec<StorageChangeSet<Hash>, Global>, Error = RpcError>
Query historical storage entries (by key) starting from a block given as the second parameter.
NOTE This first returned result contains the initial state of storage for all keys. Subsequent values in the vector represent changes to the previous state (diffs).
pub fn query_storage_at(
&self,
keys: Vec<StorageKey, Global>,
at: Option<Hash>
) -> impl Future<Item = Vec<StorageChangeSet<Hash>, Global>, Error = RpcError>[src]
