# AnyCancellable

A type-erasing cancellable object that executes a provided closure when canceled.

## Declaration

```swift
final class AnyCancellable
```

## Mentioned in

Controlling Publishing with Connectable Publishers

## Overview

Overview Subscriber implementations can use this type to provide a “cancellation token” that makes it possible for a caller to cancel a publisher, but not to use the Subscription object to request items. An AnyCancellable instance automatically calls cancel() when deinitialized.
