Enum components::ScrollDirection [−][src]
#[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.
Scroll up
Scroll down
Scroll left
Scroll right
Precise scrolling delta (available in 1.10)
