Available on crate feature wayland and Linux only.

Describes a scroll along one axis

Fields

absolute: f64

The scroll measured in pixels.

discrete: i32

The scroll measured in steps.

Note: this might always be zero if the scrolling is due to a touchpad or other continuous source.

This event is deprecated and will be sent only by older compositors.

value120: i32

High-resolution wheel scroll information, with each multiple of 120 representing one logical scroll step.

relative_direction: Option<AxisRelativeDirection>

Relative directional information of the entity causing the axis motion.

stop: bool

The scroll was stopped.

Generally this is encountered when hardware indicates the end of some continuous scrolling.

Implementations

impl AxisScroll

pub fn is_none(&self) -> bool

Returns true if there was no movement along this axis.

Trait Implementations

impl Clone for AxisScroll

fn clone(&self) -> AxisScroll

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AxisScroll

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

Formats the value using the given formatter.

impl Default for AxisScroll

fn default() -> AxisScroll

Returns the “default value” for a type.

impl PartialEq for AxisScroll

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

impl Copy for AxisScroll
