Implementations

impl MockTrieCursor

pub const fn new( trie_nodes: Arc<BTreeMap<Nibbles, BranchNodeCompact>>, visited_keys: Arc<Mutex<Vec<KeyVisit<Nibbles>>>>, ) -> Self

Creates a new mock trie cursor for accounts with the given trie nodes and key tracking.

pub fn new_storage( all_storage_tries: Arc<B256Map<BTreeMap<Nibbles, BranchNodeCompact>>>, all_visited_storage_keys: Arc<B256Map<Mutex<Vec<KeyVisit<Nibbles>>>>>, hashed_address: B256, ) -> Result<Self, DatabaseError>

Creates a new mock trie cursor for storage with access to all storage tries.

Trait Implementations

impl Debug for MockTrieCursor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl TrieCursor for MockTrieCursor

fn seek_exact( &mut self, key: Nibbles, ) -> Result<Option<(Nibbles, BranchNodeCompact)>, DatabaseError>

Move the cursor to the key and return if it is an exact match.

fn seek( &mut self, key: Nibbles, ) -> Result<Option<(Nibbles, BranchNodeCompact)>, DatabaseError>

Move the cursor to the key and return a value matching of greater than the key.

fn next( &mut self, ) -> Result<Option<(Nibbles, BranchNodeCompact)>, DatabaseError>

Move the cursor to the next key.

fn current(&mut self) -> Result<Option<Nibbles>, DatabaseError>

Get the current entry.

fn reset(&mut self)

Reset the cursor to the beginning.

impl TrieStorageCursor for MockTrieCursor

fn set_hashed_address(&mut self, hashed_address: B256)

Set the hashed address for the storage trie cursor.
