Struct BackendTrieDB 

pub struct BackendTrieDB { /* private fields */ }

TrieDB implementation that holds a pre-acquired read view for the entire trie traversal, avoiding per-node-lookup allocation and lock acquisition.

Implementations

impl BackendTrieDB

pub fn new_for_accounts( db: Arc<dyn StorageBackend>, last_written: Vec<u8>, ) -> Result<Self, StoreError>

Create a new BackendTrieDB for the account trie

pub fn new_for_accounts_with_view( db: Arc<dyn StorageBackend>, read_view: Arc<dyn StorageReadView>, last_written: Vec<u8>, ) -> Result<Self, StoreError>

Create a new BackendTrieDB for the account trie with a shared read view

pub fn new_for_storages( db: Arc<dyn StorageBackend>, last_written: Vec<u8>, ) -> Result<Self, StoreError>

Create a new BackendTrieDB for the storage tries

pub fn new_for_storages_with_view( db: Arc<dyn StorageBackend>, read_view: Arc<dyn StorageReadView>, last_written: Vec<u8>, ) -> Result<Self, StoreError>

Create a new BackendTrieDB for the storage tries with a shared read view

pub fn new_for_account_storage( db: Arc<dyn StorageBackend>, address_prefix: H256, last_written: Vec<u8>, ) -> Result<Self, StoreError>

Create a new BackendTrieDB for a specific storage trie

pub fn new_for_account_storage_with_view( db: Arc<dyn StorageBackend>, read_view: Arc<dyn StorageReadView>, address_prefix: H256, last_written: Vec<u8>, ) -> Result<Self, StoreError>

Create a new BackendTrieDB for a specific storage trie with a shared read view
