Enum WheelDelta

pub enum WheelDelta {
    LineDelta {
        x: f32,
        y: f32,
    },
    PixelDelta {
        x: f32,
        y: f32,
    },
}

Scroll wheel delta in lines or pixels.

Examples

use ailloli_ui_core::event::WheelDelta;
let delta = WheelDelta::PixelDelta { x: 1.0, y: -2.0 };
assert!(matches!(delta, WheelDelta::PixelDelta { .. }));

Variants

Trait Implementations

impl Clone for WheelDelta

fn clone(&self) -> WheelDelta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WheelDelta

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

Formats the value using the given formatter.

impl PartialEq for WheelDelta

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