Struct WheelResolution 

pub struct WheelResolution {
    pub native_res: u16,
    pub diverted_res: u16,
}

What one revolution of the wheel measures in each reporting mode.

The two are not the same unit: an MX Master 4 reports 20 ratchets per revolution natively and 120 increments per revolution diverted. Anything re-synthesising scroll from diverted increments has to scale by the ratio, or the same physical motion scrolls six times as far as it did before the wheel was diverted.

Fields

native_res: u16

Ratchets per revolution in native (HID) mode.

diverted_res: u16

Rotation increments per revolution in diverted (HID++) mode.

Implementations

impl WheelResolution

pub const UNKNOWN: Self

Resolutions a wheel did not report, scaling increments through unchanged.

pub fn native_per_increment(self) -> f32

Native scroll units one diverted increment is worth.

1.0 when either resolution is missing — a wheel that did not answer getThumbwheelInfo keeps the raw increment-per-unit behavior rather than having its scroll silently scaled by a guess.
