source

pub fn storage_keys(
 &self,
 prefix: StorageKey,
 hash: Option<Hash>
) -> impl Future<Item = Vec<StorageKey>, Error = RpcError>

) -> impl Future<Item = Vec<StorageKey>, Error = RpcError>

Returns the keys with prefix with pagination support. Up to count keys will be returned. If start_key is passed, return next keys in storage in lexicographic order.

source

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

Returns a storage entry at a specific block’s state.

) -> impl Future<Item = Vec<StorageChangeSet<Hash>>, 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).

source

pub fn query_storage_at(
 &self,
 keys: Vec<StorageKey>,
 at: Option<Hash>
) -> impl Future<Item = Vec<StorageChangeSet<Hash>>, Error = RpcError>

Query storage entries (by key) starting at block hash given as the second parameter.
