zng::var::animation::easing

Type Alias EasingStep

source
pub type EasingStep = Factor;
Expand description

Easing function output.

Usually in the [0..=1] range, but can overshoot. An easing function converts a EasingTime into this factor.

§Examples

use zng_unit::*;
use zng_var::animation::easing::{EasingStep, EasingTime};

/// Cubic animation curve.
fn cubic(time: EasingTime) -> EasingStep {
    let f = time.fct();
    f * f * f
}

Note that all the common easing functions are implemented in easing.
