}

Interface to the runtime host to fetch historic information.

Required Methods

fn consensus_state_at(&self, height: u64) -> Result<ConsensusState, Error>

Fetch historic consensus state after executing the block at given height.

fn consensus_events_at( &self, height: u64, kind: EventKind ) -> Result<Vec<Event>, Error>

Fetch events emitted during execution of the block at given height.
