Struct zng::scroll::SmoothScrolling

pub struct SmoothScrolling {
    pub duration: Duration,
    pub easing: Arc<dyn Fn(EasingTime) -> Factor + Sync + Send>,
}

Smooth scrolling config.

This config can be set by the smooth_scrolling property.

Fields

duration: Duration

Chase transition duration.

Default is 150.ms().

easing: Arc<dyn Fn(EasingTime) -> Factor + Sync + Send>

Chase transition easing function.

Default is linear.

Implementations

impl SmoothScrolling

pub fn new( duration: Duration, easing: impl Fn(EasingTime) -> Factor + Send + Sync + 'static, ) -> SmoothScrolling

New custom smooth scrolling config.

pub fn disabled() -> SmoothScrolling

No smooth scrolling, scroll position updates immediately.

pub fn is_disabled(&self) -> bool

If this config represents disabled.

type Var = LocalVar<SmoothScrolling>

Variable type that will wrap the T value.

fn into_var(self) -> <(Duration, EasingFn) as IntoVar<SmoothScrolling>>::Var

Converts the source value into a var.

fn into_boxed_var(self) -> Box<dyn VarBoxed<T>>

impl PartialEq for SmoothScrolling

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