Enum AnimationTiming 

#[repr(C, u8)]
pub enum AnimationTiming {
    Ease,
    Linear,
    EaseIn,
    EaseOut,
    EaseInOut,
    Spring,
    SpringGentle,
    SpringSnappy,
    CubicBezier(AnimationTimingBezier),
}

Timing for StyleAnimation.

The CSS keywords, the engine’s spring presets, and a custom cubic-bezier(...) point list — permille-encoded (see AnimationTimingBezier) because this enum lives inside CssProperty, which derives Eq + Hash + Ord, and raw f32 control points cannot. Converted via Self::to_interpolation at the engine boundary; native animation functions receive the DECLARED timing on ZombieAnimInfo together with raw linear progress, so a callback can apply this math — or its own — via Self::evaluate.

Variants

Ease

Linear

EaseIn

EaseOut

EaseInOut

Spring

The engine’s default spring (SMOOTH).

SpringGentle

SpringSnappy

CubicBezier(AnimationTimingBezier)

cubic-bezier(x1, y1, x2, y2), control points in permille. 8 bytes vs the unit variants — boxing is not an option: this is a repr(C, u8) ABI enum whose layout the C bindings depend on.

Implementations

impl AnimationTiming

pub fn to_interpolation(self) -> AnimationInterpolationFunction

The runtime interpolation this timing stands for.

pub fn evaluate(self, t: f32) -> f32

Eased progress for raw linear t — the one-call way for a native animation function to honour the timing the CSS requested.

pub fn as_css_string(self) -> String

pub fn from_css_str(s: &str) -> Option<Self>

Trait Implementations

impl Clone for AnimationTiming

fn clone(&self) -> AnimationTiming

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AnimationTiming

impl Debug for AnimationTiming

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

Formats the value using the given formatter.

impl Default for AnimationTiming

fn default() -> AnimationTiming

Returns the “default value” for a type.

impl Eq for AnimationTiming

impl Hash for AnimationTiming

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for AnimationTiming

fn cmp(&self, other: &AnimationTiming) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for AnimationTiming

fn eq(&self, other: &AnimationTiming) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for AnimationTiming

fn partial_cmp(&self, other: &AnimationTiming) -> Option<Ordering>

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
