Struct PointerMotionScalingFeature 

pub struct PointerMotionScalingFeature { /* private fields */ }

Implements the PointerMotionScaling / 0x2205 feature.

Implementations

impl PointerMotionScalingFeature

pub async fn get_pointer_scaling(&self) -> Result<PointerScaling, Hidpp20Error>

Retrieves the current scaling (GetPointerScalingValue).

pub async fn set_pointer_scaling( &self, scaling: PointerScaling, ) -> Result<PointerScaling, Hidpp20Error>

Requests a new scaling (SetPointerScalingValue) and returns the value the device echoes. The spec allows firmware to clip the request, so read the value back when the applied scaling matters.

Trait Implementations

impl Clone for PointerMotionScalingFeature

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CreatableFeature for PointerMotionScalingFeature

const ID: u16 = 8709u16

The protocol ID of the implemented feature.

const STARTING_VERSION: u8 = 0u8

The version of the feature the implementation starts to support.

fn new(chan: Arc<HidppChannel>, device_index: u8, feature_index: u8) -> Self

Creates a new instance of the feature implementation.
