# ResolverSpecification

An internal type that a resolver uses to convert data values.

## Declaration

```swift
protocol ResolverSpecification : Hashable, Sendable, Sequence where Self.Element == any Resolver
```

## Overview

Overview Don’t use a ResolverSpecification type directly in your code. The system uses this type internally to manage the resolution process.
