pub fn frames() -> Subscription<(Id, Instant)>Expand description
Subscribes to the frames of the window of the running application.
The resulting Subscription will produce items at a rate equal to the
refresh rate of the first application window. Note that this rate may be variable, as it is
normally managed by the graphics driver and/or the OS.
In any case, this Subscription is useful to smoothly draw application-driven
animations without missing any frames.
