VoteCollector is changed to return Result<bool, DoubleVote>. Rust
compiler will force you to check whether there was a double vote.

I'll remove @majecty from the reviewers since he is vacant. @HoOngEe Would you review this?
Here are the review points:

  • "Cleanup vote functions" is a refactoring. You should carefully review whether I've changed the behavior accidentally.
  • "Fix to use Err(DoubleVote) from VoteCollector" is adding missing assertions. It should not change the behavior unless the node tries to double vote. In that case, the node should crash immediately since there's no way to recover from the error.
  • Other commits: They have straightforward names and tests. I think checking styles and consistencies would be enough.
