Struct zng_wgt_scroll::SmoothScrolling

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

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) -> EasingStep + Send + Sync>

Chase transition easing function.

Default is linear.

Implementations

impl SmoothScrolling

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

New custom smooth scrolling config.

pub fn disabled() -> Self

No smooth scrolling, scroll position updates immediately.

pub fn is_disabled(&self) -> bool

If this config represents disabled.

Trait Implementations

impl Clone for SmoothScrolling

fn clone(&self) -> SmoothScrolling

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SmoothScrolling

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

Formats the value using the given formatter.

impl Default for SmoothScrolling

fn default() -> Self

Returns the “default value” for a type.

impl From<(Duration, EasingFn)> for SmoothScrolling

fn from((duration, easing): (Duration, EasingFn)) -> Self

Converts to this type from the input type.

impl<F: Fn(EasingTime) -> EasingStep + Send + Sync + 'static> From<(Duration, F)> for SmoothScrolling

fn from((duration, easing): (Duration, F)) -> Self

Converts to this type from the input type.

impl From<Duration> for SmoothScrolling

fn from(duration: Duration) -> Self

Linear duration of smooth transition.

impl From<bool> for SmoothScrolling

fn from(enabled: bool) -> Self

Returns default config for true, disabled for false.

impl IntoVar<SmoothScrolling> for (Duration, EasingFn)

type Var = LocalVar<SmoothScrolling>

Variable type that will wrap the T value.

fn into_var(self) -> Self::Var

Converts the source value into a var.

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

where Self: Sized,

Converts into BoxedVar<T>.

type Var = LocalVar<SmoothScrolling>

Variable type that will wrap the T value.

fn into_var(self) -> Self::Var

Converts the source value into a var.

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

where Self: Sized,

Converts into BoxedVar<T>.

impl IntoVar<SmoothScrolling> for Duration

fn into_var(self) -> Self::Var

Linear duration of smooth transition.

type Var = LocalVar<SmoothScrolling>

Variable type that will wrap the T value.

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

where Self: Sized,

Converts into BoxedVar<T>.

impl IntoVar<SmoothScrolling> for bool

fn into_var(self) -> Self::Var

Returns default config for true, disabled for false.

type Var = LocalVar<SmoothScrolling>

Variable type that will wrap the T value.

impl PartialEq for SmoothScrolling

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