Source

pub fn tick( &mut self, context: &ScreenContext, network_idle: bool, ) -> Vec<CelEvent>

Compare the current context against the previous snapshot and emit events.

context: The current screen context. network_idle: Whether the network monitor reports idle state.

Returns a list of events that occurred since the last tick.

Source

pub fn merge_events(&self, events: Vec<CelEvent>) -> Vec<CelEvent>

Merge source-specific push events that have already been normalized to CEL events.

Source

pub fn merge_ax_events<T>(&self, _events: Vec<T>) -> Vec<CelEvent>

Compatibility shim for runtimes that still receive source-specific accessibility events. Convert those events before calling merge_events if push-event fidelity matters.
