impl<Block, B> VotingRule<Block, B> for ThreeQuartersOfTheUnfinalizedChain
where Block: BlockT, B: HeaderBackend<Block>,

source§

fn restrict_vote( &self, backend: Arc<B>, base: &Block::Header, best_target: &Block::Header, current_target: &Block::Header, ) -> VotingRuleResult<Block>

Restrict the given current_target vote, returning the block hash and number of the block to vote on, and None in case the vote should not be restricted. base is the block that we’re basing our votes on in order to pick our target (e.g. last round estimate), and best_target is the initial best vote target before any vote rules were applied. When applying multiple VotingRules both base and best_target should remain unchanged. Read more
