Enum WheelStep 

pub enum WheelStep {
    Scroll(f64),
    Fling,
    Ignored,
}

What a vertical collection should do with one wheel event, decided by ScrollMomentum::wheel.

Variants

Scroll(f64)

Move the content by this many logical pixels now, then report whether it moved through ScrollMomentum::wheel_applied.

Fling

A continuous gesture ended fast enough to keep gliding; the momentum is now active and the event is consumed.

Ignored

Nothing to do (a phase marker, or a gesture that ended at rest).

Trait Implementations

impl Clone for WheelStep

fn clone(&self) -> WheelStep

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WheelStep

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

Formats the value using the given formatter.

impl PartialEq for WheelStep

fn eq(&self, other: &WheelStep) -> 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 WheelStep
