Enum ScrollSource 

#[non_exhaustive]
pub enum ScrollSource {
    Wheel,
    Finger,
    Continuous,
}

Where a scroll came from.

It changes what the scroll means. A wheel click is a discrete step and should move a fixed amount; a finger on a touchpad is continuous and wants kinetic scrolling, and its end is a real event – the finger lifting – rather than the absence of one.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Wheel

A mouse wheel, in discrete clicks.

Finger

One or more fingers on a touchpad.

Continuous

A continuous source, such as a button held and the device moved.
