Rating

This library provides an easy and type-safe way to maintain player's ratings.

Example

````rust use rating::{CalculateRating, EloStrategy, GameResult, Rating};

fn main() { let alice = Rating::from(1200); let bob = Rating::from(1453);

let elo_calculator = EloStrategy::new(40);
// the game result it's seen from the first player perspective, in this case Alice
let (alice_new_rating, bob_new_rating) = elo_calculator.calculate(alice, bob, GameResult::Win);

println!("Alice: {alice_new_rating}");
println!("Bob: {bob_new_rating}");

// Alice: 1232.4
// Bob: 1420.6

} ````

Currently, it only implements the classical Elo rating system, widely used in the chess community.
