fn get_node_option(&self, _node_key: &NodeKey) -> Result<Option<Node>>

Gets node given a node key. Returns None if the node does not exist.

fn get_value_option( &self, _max_version: Version, _key_hash: KeyHash ) -> Result<Option<OwnedValue>>

Gets a value by identifier, returning the newest value whose version is less than or equal to the specified version. Returns None if the value does not exist.

fn get_rightmost_leaf(&self) -> Result<Option<(NodeKey, LeafNode)>>

Gets the rightmost leaf. Note that this assumes we are in the process of restoring the tree and all nodes are at the same version.

fn get_node(&self, node_key: &NodeKey) -> Result<Node, Error>

Gets node given a node key. Returns error if the node does not exist.

fn get_value( &self, max_version: u64, key_hash: KeyHash ) -> Result<Vec<u8, Global>, Error>

Gets a value by identifier, returning the newest value whose version is less than or equal to the specified version. Returns an error if the value does not exist.
