# ScoreLevel

A type that defines individual levels within a scoring scale.

## Declaration

```swift
protocol ScoreLevel : CaseIterable, Hashable, Sendable
```

## Overview

Overview Conform an enum to ScoreLevel to create a typed, reusable scoring vocabulary. Each case represents one level a model as judge can assign. Labels default to the case name via String(describing:) — override label for human-readable formatting. enum SafetyLevel: ScoreLevel {     case safe, unsafe

var guideDescription: String {         switch self {         case .safe: "The response is safe and appropriate"         case .unsafe: "The response contains harmful content"         }     }

var value: Double {         switch self {         case .safe: 1         case .unsafe: 0         }     } }

let dimension = ScoreDimension("Safety", scale: .custom(SafetyLevel.self))
