Struct EventSelector 

pub struct EventSelector { /* private fields */ }

Tracks active events and dirty regions for optimized rendering

Implementations

impl EventSelector

pub fn new() -> Self

Create a new event selector

pub fn set_render_comments(&mut self, render: bool)

Set whether to render comment events

pub fn select_active<'a>( &mut self, script: &'a Script<'a>, time_cs: u32, ) -> Result<ActiveEvents<'a>, RenderError>

Select active events and track changes for incremental rendering.

time_cs is in centiseconds. An event is active when start <= time_cs < end — the start is inclusive and the end is exclusive, matching libass (Start <= now < Start + Duration). The exclusive end is what stops two events that share a boundary timestamp (one ending exactly as the next begins) from both rendering for a frame and stacking on top of each other.

pub fn add_dirty_region(&mut self, x: u32, y: u32, width: u32, height: u32)

Add a dirty region for partial re-rendering

pub fn dirty_regions(&self) -> &[DirtyRegion]

Get current dirty regions

pub fn clear_dirty_regions(&mut self)

Clear dirty regions after rendering

pub fn reset(&mut self)

Reset selector state
