Trait cumulus_pallet_parachain_system::consensus_hook::ConsensusHook

        state_proof: &RelayChainStateProof
    ) -> (Weight, UnincludedSegmentCapacity);
}
Expand description

The consensus hook for dealing with the unincluded segment.

Higher-level and user-configurable consensus logic is more informed about the desired unincluded segment length, as well as any rules for adapting it dynamically according to the relay-chain state.

Required Methods§

source

fn on_state_proof( state_proof: &RelayChainStateProof ) -> (Weight, UnincludedSegmentCapacity)

This hook is called partway through the set_validation_data inherent in parachain-system.

The hook is allowed to panic if customized consensus rules aren’t met and is required to return a maximum capacity for the unincluded segment with weight consumed.
