Enum Interpolation 

pub enum Interpolation {
    Hold,
    Linear,
    CubicBezier(CubicBezier),
}

Interpolation from one keyframe to the next.

Values are interpolated numerically: a rotation from 0 to 720 degrees turns twice, and one from 0 to 360 turns once. A host that wants the shortest path normalizes its keyframe values.

Variants

Hold

Keep this keyframe’s value until the next keyframe.

Linear

Move to the next value at a constant rate.

CubicBezier(CubicBezier)

Move to the next value along a CSS cubic-bezier() timing curve.

Implementations

impl Interpolation

pub fn amount(self, progress: f64) -> Option<f64>

The fraction of the way to the next value at linear segment progress (clamped to 0..=1), or None while holding.

A cubic Bezier curve may overshoot, so the fraction can leave 0..=1.

pub fn is_valid(self) -> bool

Whether the interpolation’s parameters are usable.
