Implementations

impl AnimationState

pub fn new(frames: Vec<(RgbaImage, Duration)>, loop_count: Option<u32>) -> Self

Build from decoded frames + loop count. Starts playing at frame 0.

pub fn current_frame(&self) -> &RgbaImage

pub fn frame_index(&self) -> usize

pub fn frame_count(&self) -> usize

pub fn is_playing(&self) -> bool

pub fn is_finished(&self) -> bool

pub fn advance(&mut self, dt: Duration) -> bool

Accumulate dt, flipping to later frames as each delay elapses (a large dt may cross several frames). On wrapping past the last frame, count a loop; if a finite loop count is then reached, finish and rest on the last frame. No-op when paused, finished, or single-frame. Returns whether the displayed frame changed.

pub fn next_deadline(&self) -> Option<Duration>

Time until the next frame flip, or None when paused/finished/single-frame.

pub fn toggle_pause(&mut self)

Play/pause toggle. Reviving a finished animation restarts it (so the play key brings a stopped GIF back to life).

pub fn step(&mut self, delta: i32)

Pause and move ±1 frame (wrapping). Clears the finished state.

pub fn restart(&mut self)

Restart from frame 0, playing, loop counter reset.
