FrameTimingsRef

public struct FrameTimingsRef : FrameTimingsProtocol

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

A GdkFrameTimings object holds timing information for a single frame of the application’s displays. To retrieve GdkFrameTimings objects, use gdk_frame_clock_get_timings() or gdk_frame_clock_get_current_timings(). The information in GdkFrameTimings is useful for precise synchronization of video with the event or audio streams, and for measuring quality metrics for the application’s display, such as latency and jitter.

  • ptr 
    Untyped pointer to the underlying `GdkFrameTimings` instance.

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