Expand description

An UnhandledInputHandler is like an InputHandler, but only deals in unhandled events.

Required Methods§

Source

fn handle_unhandled_input_event<'async_trait>( self: Rc<Self>, unhandled_input_event: UnhandledInputEvent, ) -> Pin<Box<dyn Future<Output = Vec<InputEvent>> + 'async_trait>>
where Self: 'async_trait,

Returns a vector of InputEvents to propagate to the next InputHandler.

The vector may be empty if, e.g., the handler chose to buffer the event.
The vector may have multiple events if, e.g.,
- the handler chose to release previously buffered events, or
- the handler unpacked a single event into multiple events
