Enum MouseScrollEvent 

pub enum MouseScrollEvent {
    Up(u16),
    Down(u16),
    Continuous(i16),
}

Available on crate feature input only.

Mouse scroll wheel ‘up’ or ‘down’ event, possibly continuous.

Variants

Up(u16)

One or more full up-scroll events.

Equivalent to Self::Continuous with a multiple of Self::WHEEL_DELTA.

Down(u16)

One or more full down-scroll events.

Equivalent to Self::Continuous with a multiple of -Self::WHEEL_DELTA.

Continuous(i16)

Continuous ‘up’ (positive value) or ‘down’ (negative value) scroll event.

Values other than multiples of positive or negative Self::WHEEL_DELTA are used for mouses with continuous scroll wheels.

Implementations

impl MouseScrollEvent

pub const WHEEL_DELTA: i16 = 120i16

pub fn send(self) -> Result<()>

Globally sends a single scroll event.

impl Clone for MouseScrollEvent

fn clone(&self) -> MouseScrollEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MouseScrollEvent

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

Formats the value using the given formatter.

impl PartialEq for MouseScrollEvent

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