Enum animate::ScrollDirection

#[non_exhaustive]
pub enum ScrollDirection {
    Up,
    Down,
    Left,
    Right,
    Smooth,
    // some variants omitted
}

Direction of a pointer scroll event.

The ScrollDirection::Smooth value implies that the ScrollEvent has precise scrolling delta information.

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.

Up

Scroll up

Down

Scroll down

Left

Scroll left

Right

Scroll right

Smooth

Precise scrolling delta (available in 1.10)
