Expand description

The factory trait for creating cursors over the hashed state.

Required Associated Types§

type AccountCursor: HashedCursor<Value = Account>

The hashed account cursor type.

type StorageCursor: HashedStorageCursor<Value = Uint<256, 4>>

The hashed storage cursor type.

Required Methods§

fn hashed_account_cursor(&self) -> Result<Self::AccountCursor, DatabaseError>

Returns a cursor for iterating over all hashed accounts in the state.

fn hashed_storage_cursor( &self, hashed_address: FixedBytes<32>, ) -> Result<Self::StorageCursor, DatabaseError>

Returns a cursor for iterating over all hashed storage entries in the state.
