Helper trait get access to the full state data of the database

Required Methods

fn as_dyn(&self) -> &dyn DatabaseRef<Error = DatabaseError>

Returns a reference to the database as a dyn DatabaseRef.

fn clear_into_state_snapshot(&mut self) -> StateSnapshot

Clear the state and move it into a new StateSnapshot.

fn read_as_state_snapshot(&self) -> StateSnapshot

Read the state snapshot.

This clones all the states and returns a new StateSnapshot.

fn clear(&mut self)

Clears the entire database

fn init_from_state_snapshot(&mut self, state_snapshot: StateSnapshot)

Reverses clear_into_snapshot by initializing the db’s state with the state snapshot.

Provided Methods

fn maybe_as_full_db(&self) -> Option<&HashMap<Address, DbAccount>>
