#[non_exhaustive]
pub enum MouseScrollDelta {
    LineDelta(f32, f32),
    PixelDelta(PhysicalPosition<f64>),
}

Expand description

Describes a difference in the mouse scroll wheel state.

Variants (Non-exhaustive)

This enum is marked as 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.

`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.
