Structs

• ArcDeltaDbWrapper
• AtomicCommit
• AtomicCommitTransaction
• CompressedPathRaw
• ConsensusParam
  Consensus parameter is only configurable in test mode.
• CowNodeRef
  CowNodeRef facilities access and modification to trie nodes in multi-version MPT. It offers read-only access to the original trie node, and creates an unique owned trie node once there is any modification. The ownership is maintained centralized in owned_node_set which is passed into many methods as argument. When CowNodeRef is created from an owned node, the ownership is transferred into the CowNodeRef object. The visitor of MPT makes sure that ownership of any trie node is not transferred more than once at the same time.
• DeltaMptIdGen
• DeltaMptIterator
• FullSyncVerifier
• KvdbRocksdb
• KvdbSqlite
• KvdbSqliteStatements
• MaybeNodeRefDeltaMptCompact
• MemOptimizedTrieNode
  A node consists of an optional compressed path (concept of Patricia Trie), an optional ChildrenTable (if the node is intermediate), an optional value attached, and the Merkle hash for subtree.
• MptSlicer
• MultiVersionMerklePatriciaTrie
• NodeMerkleProof
• NodeRefDeltaMptCompact
  The MSB is used to indicate if a node is in mem or on disk, the rest 31 bits specifies the index of the node in the memory region.
• OpenDeltaDbLru
• OwnedNodeSet
  A container to store information about owned nodes.
• RecordingStorage
• ReplicatedState
• Slab
  Pre-allocated storage for a uniform data type. The modified slab offers thread-safety without giant lock by mimicking the behavior of independent pointer at best.

• SqliteConnection
• StateProof
• StateProofMerger
• StorageConfiguration
• SubTrieVisitor

Constants

• DEFAULT_NODE_MAP_SIZE

Traits

• KVInserter
  Classes implement KVInserter is used to store key-values in MPT iteration.
• OpenableOnDemandOpenDeltaDbTrait

Functions

• into_simple_mpt_key
  Given an integer-indexed SimpleMpt with num_keys elements stored in it, convert key into the corresponding key format.
• make_simple_mpt
• rlp_key_value_len
  We assume that the keys and values are serialized in separate vector, therefore we only add up those rlp string lengths. The rlp bytes for the up-most structures are ignored for sync slicer.
