Enum ScrollDelta 

pub enum ScrollDelta {
    Lines {
        x: f32,
        y: f32,
    },
    Pixels {
        x: f32,
        y: f32,
    },
}

Positive y scrolls content up (wheel away from the user) by convention.

Variants

Fields

x: f32

y: f32

Vertical lines.

Pixels

y: f32

Vertical pixels.

Trait Implementations

impl Clone for ScrollDelta

fn clone(&self) -> ScrollDelta

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ScrollDelta

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ScrollDelta

fn eq(&self, other: &ScrollDelta) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
