Struct diem_jellyfish_merkle::restore::JellyfishMerkleRestore

pub struct JellyfishMerkleRestore<V> { /* private fields */ }

Implementations

impl<V> JellyfishMerkleRestore<V>where V: Value,

pub fn new<D: 'static + TreeReader<V> + TreeWriter<V>>( store: Arc<D>, version: Version, expected_root_hash: HashValue ) -> Result<Self>

pub fn new_overwrite<D: 'static + TreeWriter<V>>( store: Arc<D>, version: Version, expected_root_hash: HashValue ) -> Result<Self>

pub fn add_chunk( &mut self, chunk: Vec<(HashValue, V)>, proof: SparseMerkleRangeProof ) -> Result<()>

Restores a chunk of accounts. This function will verify that the given chunk is correct using the proof and root hash, then write things to storage. If the chunk is invalid, an error will be returned and nothing will be written to storage.

pub fn finish(self) -> Result<()>

Finishes the restoration process. This tells the code that there is no more account, otherwise we can not freeze the rightmost leaf and its ancestors.
