Struct MultiStateAnimator 

pub struct MultiStateAnimator<T: Interpolatable, const N: usize> { /* private fields */ }

Multi-state animator for keyframe-based animations.

This animator supports multiple keyframes with different easing functions between each pair. It automatically determines which keyframe pair to interpolate between based on the current progress.

Implementations

impl<T: Interpolatable, const N: usize> MultiStateAnimator<T, N>

pub fn new() -> Self

Create a new multi-state animator.

pub fn add_keyframe( &mut self, progress: Progress, state: T, easing: EasingFunction, ) -> ChartResult<()>

Add a keyframe at the specified progress.

Arguments

• progress - Progress position (0-100)
• state - State at this keyframe
• easing - Easing function to use when transitioning TO this keyframe

Returns

Ok(()) on success, Err if the animator is full

pub fn value_at(&self, progress: Progress) -> Option<T>

Get the interpolated value at the given progress.

Arguments

• progress - Animation progress (0-100)

Returns

The interpolated value, or None if no keyframes are set

pub fn keyframe_count(&self) -> usize

Get the number of keyframes.

pub fn clear(&mut self)

Clear all keyframes.
