Struct AnimatedThumbnail 

pub struct AnimatedThumbnail {
    pub width: u32,
    pub height: u32,
    pub frames: Vec<AnimatedFrame>,
    pub total_duration_ms: u64,
    pub loop_count: u32,
}

An animated thumbnail consisting of multiple frames with timing.

Represents a short looping preview (e.g. 2–5 seconds) from key moments in a video. The frames are raw RGBA with per-frame duration.

Fields

width: u32

Width of each frame in pixels.

height: u32

Height of each frame in pixels.

frames: Vec<AnimatedFrame>

Frames with their display durations.

total_duration_ms: u64

Total duration of the animation in milliseconds.

loop_count: u32

Number of times to loop (0 = infinite).

Implementations

impl AnimatedThumbnail

pub fn from_thumbnails( thumbnails: &[Thumbnail], frame_duration_ms: u64, loop_count: u32, ) -> Option<Self>

Creates a new animated thumbnail from a list of source thumbnails.

Each thumbnail is assigned a uniform frame duration. Returns None if thumbnails is empty or dimensions are zero.

pub fn frame_count(&self) -> usize

Returns the number of frames in the animation.

pub fn total_byte_size(&self) -> usize

Returns the total byte size of all frame data.

pub fn from_smart_selection( thumbnails: &[Thumbnail], max_frames: usize, frame_duration_ms: u64, loop_count: u32, ) -> Option<Self>

Creates an animated thumbnail from the most interesting frames, selected by luminance variance.

Trait Implementations

impl Clone for AnimatedThumbnail

fn clone(&self) -> AnimatedThumbnail

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnimatedThumbnail

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
