# AnySubscriber

A type-erasing subscriber.

## Declaration

```swift
@frozen struct AnySubscriber<Input, Failure> where Failure : Error
```

## Overview

Overview Use an AnySubscriber to wrap an existing subscriber whose details you don’t want to expose. You can also use AnySubscriber to create a custom subscriber by providing closures for the methods defined in Subscriber, rather than implementing Subscriber directly.
