Enum MouseScrollDelta 

pub enum MouseScrollDelta {
    LineDelta(f32, f32),
    PixelDelta(PhysicalPosition<f64>),
}

Describes a difference in the mouse scroll wheel state.

Variants

LineDelta(f32, f32)

Amount in lines or rows to scroll in the horizontal and vertical directions.

Positive values indicate movement forward (away from the user) or rightwards.

PixelDelta(PhysicalPosition<f64>)

Amount in pixels to scroll in the horizontal and vertical direction.

Scroll events are expressed as a PixelDelta if supported by the device (eg. a touchpad) and platform.

Trait Implementations

impl Clone for MouseScrollDelta

fn clone(&self) -> MouseScrollDelta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MouseScrollDelta

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

Formats the value using the given formatter.

impl PartialEq for MouseScrollDelta

fn eq(&self, other: &MouseScrollDelta) -> 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.
