impl VoteValidator

Source

pub fn should_grant_vote( receiver_term: Term, receiver_voted_for: &Option<NodeId>, receiver_last_log_index: u64, receiver_last_log_term: Term, candidate_id: &NodeId, candidate_term: Term, candidate_last_log_index: u64, candidate_last_log_term: Term, ) -> bool

Validate if a vote request should be granted

A vote should be granted if:

  1. The candidate’s term is at least as current as receiver’s term
  2. The receiver hasn’t voted in this term, or has voted for this candidate
  3. The candidate’s log is at least as up-to-date as receiver’s log
