pub struct LifecycleTracker { /* private fields */ }Expand description
Deduplicates raw LifecycleSnapshots into change-only LifecycleEvents.
Resizedis emitted only when the size differs from the last observed size.Focusis emitted only when the focus state flips.Closeis emitted at most once for the lifetime of the tracker.
The first snapshot that carries a size / focus value is treated as a change
(None → Some), so a backend that reports its initial geometry receives
one seeding Resized / Focus event.

impl LifecycleTracker
Sourcepub fn observe(&mut self, snap: LifecycleSnapshot) -> Vec<LifecycleEvent>
pub fn observe(&mut self, snap: LifecycleSnapshot) -> Vec<LifecycleEvent>
