Struct ScratchGestureMapper 

pub struct ScratchGestureMapper { /* private fields */ }

Converts pointer motion to physical hand setpoints.

Implementations

impl ScratchGestureMapper

pub fn new(config: ScratchGestureConfig) -> Result<Self, ScratchGestureError>

pub const fn config(&self) -> ScratchGestureConfig

pub const fn active_pointer_id(&self) -> Option<u64>

pub const fn total_late_shift_frames(&self) -> u64

pub fn begin( &mut self, sample: ScratchPointerSample, minimum_render_frame: u64, record_angle_rad: f64, ) -> Result<ScheduledScratchHandControl, ScratchGestureError>

Starts a gesture without moving the record at contact time.

pub fn update( &mut self, sample: ScratchPointerSample, minimum_render_frame: u64, ) -> Result<ScheduledScratchHandControl, ScratchGestureError>

Maps one move without low-pass filtering a reversal.

pub fn finish( &mut self, pointer_id: u64, source_time_ns: u64, minimum_render_frame: u64, ) -> Result<ScheduledScratchHandControl, ScratchGestureError>

Schedules release and makes the mapper available for another pointer.

pub fn snapshot(&self) -> ScratchGestureSnapshot

pub fn restore( &mut self, snapshot: &ScratchGestureSnapshot, ) -> Result<(), ScratchGestureError>
