Implementations

impl StateIndex

pub fn height_to_delta_height(height: u64, snapshot_epoch_count: u32) -> u32

pub fn new_for_test_only_delta_mpt(epoch_id: &EpochId) -> Self

pub fn new_for_next_epoch( base_epoch_id: &EpochId, state_root: &StateRootWithAuxInfo, height: u64, snapshot_epoch_count: u32 ) -> Self

Height is used to check for shifting snapshot. The state root and height information should be provided from consensus.

pub fn new_for_readonly( epoch_id: &EpochId, state_root: &StateRootWithAuxInfo ) -> Self

Trait Implementations

impl Debug for StateIndex

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

Formats the value using the given formatter.
