Enum Easing 

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

Easing functions for animations.

These functions define how animation progress changes over time, creating smooth and natural-looking motion.

All calculations use integer-only math with fixed-point arithmetic. The input progress is in range [0, ANIM_SCALE] and output is also in range [0, ANIM_SCALE].

Variants

Linear

Linear interpolation - constant speed.

EaseIn

Ease-in - slow start, fast end.

EaseOut

Ease-out - fast start, slow end.

EaseInOut

Ease-in-out - slow start and end.

Implementations

impl Easing

pub fn calc(&self, progress: i32) -> i32

Calculates the eased value for a given progress using integer math.

Arguments

• progress - Animation progress in range [0, ANIM_SCALE]

Returns

The eased progress value in range [0, ANIM_SCALE] (some easing functions like elastic may slightly exceed this range).

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 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.
