Implementations

impl MultiVersionMerklePatriciaTrie

pub fn new( db_manager: Arc<dyn OpenableOnDemandOpenDeltaDbTrait>, snapshot_epoch_id: EpochId, storage_manager: Arc<StorageManager>, mpt_id: u16, node_memory_manager: Arc<NodeMemoryManager<<LRU<u32, (u16, u32)> as CacheAlgorithm>::CacheAlgoData, LRU<u32, (u16, u32)>>> ) -> Result<Self>

pub fn new_single_mpt( db_manager: Arc<dyn OpenableOnDemandOpenDeltaDbTrait>, node_memory_manager: Arc<NodeMemoryManager<<LRU<u32, (u16, u32)> as CacheAlgorithm>::CacheAlgoData, LRU<u32, (u16, u32)>>> ) -> Result<Self>

pub fn get_mpt_id(&self) -> u16

pub fn start_commit( &self ) -> Result<AtomicCommitTransaction<'_, Box<DeltaDbTransactionTraitObj>>>

pub fn get_root_node_ref_by_epoch( &self, epoch_id: &EpochId ) -> Result<Option<Option<NodeRefDeltaMpt>>>

pub fn get_root_node_ref( &self, merkle_root: &MerkleHash ) -> Result<Option<NodeRefDeltaMpt>>

Find trie root by merkle root is mainly for debugging.

Trait Implementations

impl MallocSizeOf for MultiVersionMerklePatriciaTrie

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.
