Enum Easing 

pub enum Easing {
    Linear,
    EaseIn,
    EaseOut,
    EaseInOut,
    Bounce,
    Elastic,
}

Easing function for keyframe interpolation.

Controls how values transition between keyframes.

Variants

Linear

Constant speed

EaseIn

Slow start, fast end (acceleration)

EaseOut

Fast start, slow end (deceleration)

EaseInOut

Slow start and end (smooth S-curve)

Bounce

Overshoots and settles

Elastic

Spring-like oscillation

Implementations

impl Easing

pub fn apply(&self, t: f64) -> f64

Apply the easing function to a normalized time value (0.0 to 1.0).

Returns the eased value (also 0.0 to 1.0, but may exceed bounds for bounce/elastic).

pub fn from_str(s: &str) -> Option<Easing>

Parse an easing function from a string.

Trait Implementations

impl Clone for Easing

fn clone(&self) -> Easing

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Easing

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

Formats the value using the given formatter.

impl Default for Easing

fn default() -> Easing

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Easing

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Easing

fn eq(&self, other: &Easing) -> 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 Serialize for Easing

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
