Expand description

Trait for final state controller.

Required Methods§

source

fn get_fingerprint(&self) -> Hash

Get the fingerprint (hash) of the final state. Note that only one atomic write per final slot occurs, so this can be safely queried at any time.

source

fn get_slot(&self) -> Slot

Get the slot at the end of which the final state is attached

source

fn get_execution_trail_hash(&self) -> Hash

Gets the hash of the execution trail

source

fn reset(&mut self)

Reset the final state to the initial state.

USED ONLY FOR BOOTSTRAP

source

fn compute_initial_draws(&mut self) -> Result<(), FinalStateError>

Performs the initial draws.

source

fn finalize(&mut self, slot: Slot, changes: StateChanges)

Applies changes to the execution state at a given slot, and settles that slot forever. Once this is called, the state is attached at the output of the provided slot.

Panics if the new slot is not the one coming just after the current one.
