Trait Interpolate 

pub trait Interpolate: Copy {
    // Required methods
    fn lerp(self, other: Self, t: f32) -> Self;
    fn distance(self, other: Self) -> f32;
}

A value an animation can move through.

t outside 0..1 is meaningful: overshoot curves and underdamped springs deliberately pass their target, so implementations extrapolate rather than clamp.

Required Methods

fn lerp(self, other: Self, t: f32) -> Self

fn distance(self, other: Self) -> f32

How far apart two values are, in one number, so a retarget can rescale a velocity it is carrying into the new distance.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl Interpolate for Hsla

fn lerp(self, other: Self, t: f32) -> Self

Interpolates hue the short way around the wheel, so a red-to-magenta transition does not sweep through the entire spectrum.

fn distance(self, other: Self) -> f32

Measured over the same short way around the wheel that lerp travels, so the distance is the distance actually covered.

impl Interpolate for Pixels

fn lerp(self, other: Self, t: f32) -> Self

fn distance(self, other: Self) -> f32

impl Interpolate for Rems

fn lerp(self, other: Self, t: f32) -> Self

fn distance(self, other: Self) -> f32

impl Interpolate for f32

fn lerp(self, other: Self, t: f32) -> Self

fn distance(self, other: Self) -> f32
