Available on crate features test-utils only.

Mock hashed cursor.

Implementations

impl<T> MockHashedCursor<T>

pub const fn new( values: Arc<BTreeMap<B256, T>>, visited_keys: Arc<Mutex<Vec<KeyVisit<B256>>>>, ) -> Self

Creates a new mock hashed cursor for accounts with the given values and key tracking.

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

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

Trait Implementations

impl<T: Debug> Debug for MockHashedCursor<T>

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

Formats the value using the given formatter.

impl<T: Debug + Clone> HashedCursor for MockHashedCursor<T>

type Value = T

Value returned by the cursor.

fn seek( &mut self, key: B256, ) -> Result<Option<(B256, Self::Value)>, DatabaseError>

Seek an entry greater than or equal to the given key and position the cursor there. Returns the first entry with the key greater than or equal to the sought key.

fn next(&mut self) -> Result<Option<(B256, Self::Value)>, DatabaseError>

Move the cursor to the next entry and return it.

fn reset(&mut self)

Reset the cursor to its initial state.

impl<T: Debug + Clone> HashedStorageCursor for MockHashedCursor<T>

fn is_storage_empty(&mut self) -> Result<bool, DatabaseError>

Returns true if the current hashed address has no storage entries.

fn set_hashed_address(&mut self, hashed_address: B256)

Set the hashed address for the storage cursor.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
