## Declaration

enum Backing

## Summary

The underlying camera: either a live ARCamera or a playback PlaybackCamera.
Switch on this when you need to call APIs that are specific to one type (e.g. `recordedOrientation` on PlaybackCamera).
Example:

```swift
switch camera.backing {
case .ar(let arCamera):
    // ARCamera-specific APIs
case .playback(let playbackCamera):
    let orientation = playbackCamera.recordedOrientation
}
```
