Enum ScrollDirection

Source 
pub enum ScrollDirection {
    Forward,
    Backward,
}
Expand description

An enum representing a scrolling direction.

This is used with ScrollbarState::scroll.

It is useful for example when you want to store in which direction to scroll.

Variants§

§

Forward

Forward scroll direction, usually corresponds to scrolling downwards or rightwards.

§

Backward

Backward scroll direction, usually corresponds to scrolling upwards or leftwards.
