Struct InMemoryTrieCursor 

pub struct InMemoryTrieCursor<'a, C> { /* private fields */ }

A cursor to iterate over trie updates and corresponding database entries. It will always give precedence to the data from the trie updates.

Implementations

impl<'a, C: TrieCursor> InMemoryTrieCursor<'a, C>

pub fn new_account(cursor: C, trie_updates: &'a TrieUpdatesSorted) -> Self

Create new account trie cursor which combines a DB cursor and the trie updates.

pub fn new_storage( cursor: C, trie_updates: &'a TrieUpdatesSorted, hashed_address: B256, ) -> Self

Create new storage trie cursor with full trie updates reference. This allows the cursor to switch between storage tries when set_hashed_address is called.

Trait Implementations

impl<'a, C: Debug> Debug for InMemoryTrieCursor<'a, C>

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

Formats the value using the given formatter.

impl<C: TrieCursor> TrieCursor for InMemoryTrieCursor<'_, C>

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<C: TrieStorageCursor> TrieStorageCursor for InMemoryTrieCursor<'_, C>

fn set_hashed_address(&mut self, hashed_address: B256)

Set the hashed address for the storage trie cursor.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
