Required Methods

fn get_committee(&self, epoch: EpochId) -> Result<Option<Arc<Committee>>>

fn get_latest_checkpoint(&self) -> Result<VerifiedCheckpoint>

Get the latest available checkpoint. This is the latest executed checkpoint.

All transactions, effects, objects and events are guaranteed to be available for the returned checkpoint.

fn get_highest_verified_checkpoint(&self) -> Result<VerifiedCheckpoint>

Get the highest verified checkpoint. This is the highest checkpoint summary that has been verified, generally by state-sync. Only the checkpoint header is guaranteed to be present in the store.

fn get_highest_synced_checkpoint(&self) -> Result<VerifiedCheckpoint>

Get the highest synced checkpoint. This is the highest checkpoint that has been synced from state-synce. The checkpoint header, contents, transactions, and effects of this checkpoint are guaranteed to be present in the store

fn get_lowest_available_checkpoint(&self) -> Result<CheckpointSequenceNumber>

Lowest available checkpoint for which transaction and checkpoint data can be requested.

Specifically this is the lowest checkpoint for which the following data can be requested:

• checkpoints
• transactions
• effects
• events

For object availability see get_lowest_available_checkpoint_objects.

fn get_full_checkpoint_contents_by_sequence_number( &self, sequence_number: CheckpointSequenceNumber, ) -> Result<Option<FullCheckpointContents>>

Get a “full” checkpoint for purposes of state-sync “full” checkpoints include: header, contents, transactions, effects

fn get_full_checkpoint_contents( &self, digest: &CheckpointContentsDigest, ) -> Result<Option<FullCheckpointContents>>

Get a “full” checkpoint for purposes of state-sync “full” checkpoints include: header, contents, transactions, effects

Provided Methods

fn get_latest_epoch_id(&self) -> Result<EpochId>

Get the epoch of the latest checkpoint
