Module tallystick::borda

The Borda count is a family of election methods in which voters rank candidates in order of preference. nightly

Requires the nightly feature to be enabled

The Borda count determines the winner by giving each candidate, for each ballot, a number of points corresponding to the number of candidates ranked lower. Once all votes have been counted the candidate with the most points is the winner.

Example

   use tallystick::borda::DefaultBordaTally;
   use tallystick::borda::Variant;

   // Election between Alice, Bob, and Carlos with two winners.
   let mut tally = DefaultBordaTally::new(2, Variant::Borda);
   tally.add(vec!["Alice", "Bob", "Carlos"]);
   tally.add(vec!["Bob", "Carlos", "Alice"]);
   tally.add(vec!["Alice", "Bob", "Carlos"]);
   tally.add(vec!["Carlos", "Bob", "Alice"]);
   tally.add(vec!["Alice", "Carlos", "Bob"]);

   let winners = tally.winners().into_unranked();
   println!("The winners are {:?}", winners);
