}

Pre-built easing curves for use in transitions, as well as a Custom variant that can be used to specify an arbitrary easing curve via a function f: f64 -> f64 mapping a time on the unit interval to a multiplier on the unit interval.

Variants

Linear

A linear easing curve, where the interpolated value changes at a constant rate over time.

Hold

A hold easing curve, where the interpolated value remains constant until the end of the transition, at which point it jumps to the final value.

InQuad

A quadratic easing curve where the interpolated value starts slow and accelerates towards the end of the transition.

OutQuad

A quadratic easing curve where the interpolated value starts fast and decelerates towards the end of the transition.

InOutQuad

A quadratic easing curve where the interpolated value starts slow, accelerates towards the middle of the transition, and then decelerates towards the end of the transition.

InBack

A back easing curve where the interpolated value starts by briefly moving in the opposite direction before accelerating towards the final value.

OutBack

A back easing curve where the interpolated value overshoots the final value before settling back to it.

InOutBack

A back easing curve where the interpolated value starts by briefly moving in the opposite direction, then accelerates towards the final value, overshooting it before settling back to it.

Custom(Box<dyn Fn(f64) -> f64>)

A custom easing curve defined by a user-provided function that maps a time on the unit interval to a multiplier on the unit interval.

Implementations

impl EasingCurve

pub fn interpolate<T>(&self, v0: &T, v1: &T, t: f64) -> T

where T: Interpolatable,

Interpolates between v0 and v1 using t as time on the unit interval.
