Struct ParallelRenderer 

pub struct ParallelRenderer {
    pub config: ParallelRenderConfig,
}

Splits a timeline into frame chunks and renders them in parallel.

On WASM targets rayon is unavailable, so chunks are processed sequentially to keep the API surface identical across platforms.

Fields

config: ParallelRenderConfig

Render configuration.

Implementations

impl ParallelRenderer

pub fn new(config: ParallelRenderConfig) -> Self

Create a new parallel renderer.

pub fn split_chunks(&self, total_frames: u64) -> Vec<RenderChunk>

Split total_frames into a list of RenderChunks.

Each chunk covers at most config.chunk_size frames. The final chunk may be smaller.

pub fn render_parallel( &self, total_frames: u64, timeline: &Arc<Timeline>, ) -> EditResult<Vec<ParallelRenderResult>>

Render total_frames from timeline in parallel.

Returns a result per chunk. Individual chunk failures do not abort the remaining chunks — errors are captured in ParallelRenderResult::error.

pub fn render_chunk( &self, chunk: &RenderChunk, _timeline: &Arc<Timeline>, ) -> ParallelRenderResult

Render a single RenderChunk.

The current implementation counts frames and records timings; actual pixel decoding is handled by the timeline’s render pipeline.

pub fn total_frames_for(&self, total_frames: u64) -> u64

Total number of frames that would be rendered given total_frames.
