Struct Keyframes 

pub struct Keyframes<T: Interpolate> { /* private fields */ }

A value that passes through named stops rather than travelling straight from one end to the other.

The stops are the whole path: sampling outside 0..=1 clamps, because an author who wrote where a value goes did not write what is past the last place they put it.

Implementations

impl<T: Interpolate> Keyframes<T>

pub fn new( theme: &Theme, spec: MotionSpec, stops: impl IntoIterator<Item = Keyframe<T>>, ) -> Option<Self>

Builds the path from stops given in any order.

None for an empty list: a path through no stops has no value to report, and every other answer would be invented.

pub fn sample(&self, progress: f32) -> T

The value at progress.

A path that does not start at 0 or reach 1 holds its nearest stop out to that end, so an author can describe only the part that moves.

pub fn offsets(&self) -> Vec<f32>

Where the stops sit along the run, in order.
