# ResolverSpecification

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

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

## Overview

Don’t use a [`ResolverSpecification`](/documentation/AppIntents/ResolverSpecification) type directly in your code. The system uses this type internally to manage the
resolution process.

## Topics

### Getting the value type
