pub type WakeFn = Arc<dyn Fn() + Send + Sync>;Available on not (WebAssembly and target feature
atomics).Expand description
Callback run after every publish, for an idle UI to come and collect the snapshot.
Without it a publish while the UI is idle, like a single step or the final one after pause, sits unread until some unrelated input event wakes the event loop. The callback must not block.
