Methods
impl Rater
impl Rater
fn update_ratings(&self, teams: Vec<Vec<Rating>>, ranks: Vec<usize>) -> Result<Vec<Vec<Rating>>, &'static str>
This method takes a vector of teams, with each team being a vector of
player ratings, and a vector ranks of the same size that specifies the
order in which the team finished a game. It returns either
Err(error_message) if the input is incorrect or
Ok(Vec<Vec<Rating>>). The returned vector is an updated version of
the teams vector that was passed into the function.
fn duel(&self, p1: Rating, p2: Rating, outcome: Outcome) -> (Rating, Rating)
This method calculates the new ratings for two players after a
head-to-head duel. The outcome is from the first player p1's
perspective, i.e. Win if the first player won, Loss if the second
player won and Draw if neither player won.
