Required Associated Types

type Error

Driver-specific error type.

Required Methods

fn idle_poll_ms(&self) -> u32

Poll interval used while the UI is idle.

fn active_poll_ms(&self) -> u32

Poll interval used while the UI is actively animating or tracking touch.

fn needs_active_poll(&self) -> bool

Returns true when the runtime should use Self::active_poll_ms.

fn delay_ms(&mut self, delay_ms: u32)

Sleeps or yields for the requested duration.

fn now_ms(&self) -> u32

Returns the current monotonic time in milliseconds.

fn poll_touch(&mut self, now_ms: u32) -> Result<Option<TouchEvent>, Self::Error>

Polls the current touch source.
