DeviceRef

public struct DeviceRef : DeviceProtocol

The DeviceRef type acts as a lightweight Swift reference to an underlying cairo_device_t instance. It exposes methods that can operate on this data type through DeviceProtocol conformance. Use DeviceRef only as an unowned reference to an existing cairo_device_t instance.

    For type-safe access, use the generated, typed pointer _ptr property instead.
