# AnyIterator

A type-erased iterator of Element.

## Declaration

```swift
@frozen struct AnyIterator<Element>
```

## Overview

Overview This iterator forwards its next() method to an arbitrary underlying iterator having the same Element type, hiding the specifics of the underlying IteratorProtocol.
