Function set_pointer_scaling 

Source 
pub async fn set_pointer_scaling(
    backend: &dyn HidBackend,
    route: &DeviceRoute,
    scaling: PointerScaling,
) -> Result<PointerScaling, WriteError>
Expand description

Write a pointer-motion scaling and return the value the device reports afterwards.

The returned read-back is the applied value: the spec lets firmware clip the request, though some devices store any non-zero value unchanged, so a caller exposing this to users must bound scaling itself.
