pub struct TimelineRenderer { /* private fields */ }

Timeline renderer.

Implementations

impl TimelineRenderer

pub fn new(timeline: Arc<Timeline>, config: RenderConfig) -> Self

Create a new timeline renderer.

pub fn mark_dirty(&mut self, start_frame: u64, end_frame: u64)

Mark a frame range [start_frame, end_frame) as dirty (needs re-render).

Overlapping or adjacent regions are coalesced automatically.

pub fn clear_dirty(&mut self)

Clear all dirty regions (mark entire timeline as clean).

pub fn force_full_redraw(&mut self)

Mark the entire timeline as dirty, forcing a full re-render.

pub fn is_position_dirty(&self, position: i64) -> bool

Returns true when the given frame position overlaps any dirty region.

If no dirty regions are tracked (empty list) the frame is always considered dirty so the renderer behaves as if all regions need updating.

pub fn prefetch_playhead(&self) -> i64

Expose the prefetch engine’s last known playhead position for tests.

pub fn set_use_parallel(&mut self, enabled: bool)

Enable or disable parallel multi-track rendering.

pub fn use_parallel(&self) -> bool

Return whether parallel rendering is active.

pub async fn render_frame_at( &mut self, position: i64, ) -> EditResult<RenderFrame>

Render a frame at a specific timeline position.

pub fn start_background_render(&mut self) -> BackgroundRenderer

Start background rendering.

pub fn clear_cache(&mut self)

Clear frame cache.
