Struct BendableScore 

pub struct BendableScore<const H: usize, const S: usize> { /* private fields */ }

A score with a configurable number of hard and soft levels.

Level counts are const generic parameters, enabling Copy and zero heap allocation.

Type Parameters

• H - Number of hard score levels
• S - Number of soft score levels

Examples

use solverforge_core::score::{BendableScore, Score};

// Create a score with 2 hard levels and 3 soft levels
let score: BendableScore<2, 3> = BendableScore::of([-1, -2], [-10, -20, -30]);

assert_eq!(score.hard_levels_count(), 2);
assert_eq!(score.soft_levels_count(), 3);
assert!(!score.is_feasible());  // Negative hard scores
