Struct SpeedKeyframe 

pub struct SpeedKeyframe {
    pub frame: u64,
    pub speed: f64,
}

A keyframe that defines speed at a specific output frame.

Fields

frame: u64

Output frame at which this keyframe applies.

speed: f64

Speed multiplier at this keyframe.

Implementations

impl SpeedKeyframe

pub fn new(frame: u64, speed: f64) -> Self

Create a new SpeedKeyframe.

pub fn interpolate_to(&self, other: &Self, t: f64) -> f64

Linearly interpolate speed toward other at t (0.0–1.0).

Returns the interpolated speed value.

pub fn t_at_frame(&self, other: &Self, frame: u64) -> Option<f64>

Compute t at a given output frame between self and other.

Returns None if the keyframes are at the same frame.
