Enum animate::ScrollSource

#[non_exhaustive]
pub enum ScrollSource {
    Unknown,
    Wheel,
    Finger,
    Continuous,
    // some variants omitted
}

The scroll source determines the source of the scroll event. Keep in mind that the source device InputDeviceType is not enough to infer the scroll source.

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.

Unknown

Source of scroll events is unknown.

Wheel

The scroll event is originated by a mouse wheel.

Finger

The scroll event is originated by one or more fingers on the device (eg. touchpads).

Continuous

The scroll event is originated by the motion of some device (eg. a scroll button is set).
