# StructuredValue

A type-safe representation of JSON values.

## Declaration

```swift
enum StructuredValue
```

## Overview

Overview let name: StructuredValue = "Alice" let score: StructuredValue = 4.5 let tags: StructuredValue = ["swift", "evaluation"] This type is not @Generable due to its recursive array/dictionary structure. For generable argument specifications, use ArgumentValue instead.
