Struct FrameSchedule 

pub struct FrameSchedule {
    pub needs_update: bool,
    pub needs_frame: bool,
    pub next_deadline: Option<Instant>,
}

What the shell needs from the platform loop next: an update now, a display frame, or a wake at a later time.

Fields

needs_update: bool

Whether queued UI tasks, state changes, layout or semantics work can run now, without waiting for a display frame.

needs_frame: bool

Whether the shell wants a display frame because something on screen changed or is animating.

next_deadline: Option<Instant>

When the next timed event, such as a cursor blink, is due. None when no timed event is waiting.

Implementations

pub fn apply_to<D>(self, driver: &D)

where D: PlatformFrameDriver + ?Sized,
