Enum EaseMethod 

pub enum EaseMethod {
    EaseFunction(EaseFunction),
    Discrete(f32),
    CustomFunction(fn(f32) -> f32),
}

Describe how eased value should be computed.

This function is applied to the cycle fraction t representing the playback position over the cycle duration. The result is used to interpolate the animation target.

In general a Lens should perform a linear interpolation over its target, and the non-linear behavior (for example, bounciness, etc.) comes from this function. This ensures the same Lens can be reused in multiple contexts, while the “shape” of the animation is controlled independently.

Default: EaseFunction::Linear.

Variants

EaseFunction(EaseFunction)

Follow EaseFunction.

Discrete(f32)

Discrete interpolation. The eased value will jump from start to end when stepping over the discrete limit, which must be value between 0 and 1.

CustomFunction(fn(f32) -> f32)

Use a custom function to interpolate the value. The function is called with the cycle ratio, in [0:1], as parameter, and must return the easing factor, typically also in [0:1]. Note that values outside this unit range may not work well with some animations; for example if animating a color, a negative red values have no meaning.
