Structs
AAdditionalInfoEvent
ACameraCaptureFailure	Struct to describe a capture failure.
ACameraCaptureSession_captureCallbacks
ACameraCaptureSession_logicalCamera_captureCallbacks	This has the same functionality as ACameraCaptureSession_captureCallbacks, with the exception that an onLogicalCameraCaptureCompleted callback is used, instead of onCaptureCompleted, to support logical multi-camera.
