Required Methods

fn get_event_list(&self) -> Arc<RwLock<EventList<'js>>>

Provided Methods

fn on_event_changed( &mut self, _event: EventKey<'js>, _added: bool, ) -> Result<()>

fn resolve_events_from( ctx: &Ctx<'js>, this: &Object<'js>, ) -> Result<Events<'js>>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
