# Empty

A publisher that never publishes any values, and optionally finishes immediately.

```
struct Empty<Output, Failure> where Failure : Error
```

## Overview

You can create a ”Never” publisher — one which never sends values and never finishes or fails — with the initializer `Empty(completeImmediately: false)`.

## Topics

### Creating an empty publisher

[`init(completeImmediately:)`](/documentation/Combine/Empty/init(completeImmediately:))

Creates an empty publisher.

[`init(completeImmediately:outputType:failureType:)`](/documentation/Combine/Empty/init(completeImmediately:outputType:failureType:))

Creates an empty publisher with the given completion behavior and output and failure types.

### Inspecting publisher properties

[`completeImmediately`](/documentation/Combine/Empty/completeImmediately)

A Boolean value that indicates whether the publisher immediately sends a completion.

### Comparing publishers

[`==(_:_:)`](/documentation/Combine/Empty/==(_:_:))

Returns a Boolean value that indicates whether two publishers are equivalent.
