Struct AnimationSequence 

pub struct AnimationSequence<T: Animatable> { /* private fields */ }

Optimized animation sequence that uses shared immutable data and atomic counters to avoid cloning sequences on step transitions

Implementations

impl<T: Animatable> AnimationSequence<T>

pub fn new() -> Self

Creates a new empty animation sequence

pub fn with_capacity(_capacity: u8) -> Self

Creates a new animation sequence with specified capacity hint Note: This is kept for API compatibility but doesn’t pre-allocate since we use Arc<[T]>

pub fn from_steps(steps: Vec<AnimationStep<T>>) -> Self

Creates a new animation sequence from a vector of steps

pub fn with_on_complete<F>(steps: Vec<AnimationStep<T>>, on_complete: F) -> Self

where F: FnOnce() + Send + 'static,

Creates a new animation sequence with a completion callback

pub fn reserve(&mut self, _additional: u8)

Reserve additional capacity (kept for API compatibility, but no-op since we use Arc<[T]>)

pub fn then(self, target: T, config: AnimationConfig) -> Self

Adds a new step to the sequence and returns a new sequence This creates a new Arc with all steps to maintain immutability

pub fn on_complete<F: FnOnce() + Send + 'static>(self, f: F) -> Self

Sets a completion callback

pub fn advance_step(&self) -> bool

Advances to the next step in the sequence Returns true if advanced, false if already at the end

pub fn current_step_index(&self) -> u8

Gets the current step index

pub fn current_step(&self) -> u8

Gets the current step index (kept for backward compatibility)

pub fn current_config(&self) -> Option<&AnimationConfig>

Gets the configuration for the current step

pub fn current_target(&self) -> Option<T>

Gets the target value for the current step

pub fn current_step_data(&self) -> Option<&AnimationStep<T>>

Gets the current step data

pub fn steps(&self) -> &[AnimationStep<T>]

Gets all steps (for backward compatibility)

pub fn is_complete(&self) -> bool

Checks if the sequence is complete (at the last step)

pub fn total_steps(&self) -> usize

Gets the total number of steps

pub fn reset(&self)

Resets the sequence to the first step

pub fn execute_completion(&self)

Executes the completion callback if present This method is thread-safe and can be called without ownership

Trait Implementations

impl<T: Animatable> Clone for AnimationSequence<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Animatable> Default for AnimationSequence<T>

fn default() -> Self

Returns the “default value” for a type.
