Struct MonoSpline 

pub struct MonoSpline { /* private fields */ }

A monotone cubic Hermite spline for C1-continuous interpolation of f32 values.

Uses the Fritsch–Carlson method to compute tangents that preserve monotonicity and prevent overshoot. Based on Android Compose’s MonoSpline.

Implementations

impl MonoSpline

pub fn new(times: Vec<f32>, values: Vec<f32>) -> Self

Build a spline from keyframe times and values. Times must be sorted ascending and have at least 2 entries. Values must have the same length as times.

Degenerate segments (duplicate/unsorted/non-finite times) are coerced to zero slope instead of producing inf/NaN tangents: dividing by a zero dt in f32 arithmetic does not panic, it silently corrupts every later evaluation, so the constructor sanitizes here.

pub fn evaluate(&self, t: f32) -> f32

Evaluate the spline at time t. Clamps t to the spline’s time range. Extrapolates using the endpoint tangent.
