Implementations

impl<'a, 'rc> RenderTargetContext<'a, 'rc>

fn get_clip_task_and_texture( &self, clip_task_index: ClipTaskIndex, offset: i32, render_tasks: &RenderTaskGraph, ) -> Option<(RenderTaskAddress, TextureSource)>

Retrieve the GPU task address for a given clip task instance. Returns None if the segment was completely clipped out. Returns Some(OPAQUE_TASK_ADDRESS) if no clip mask is needed. Returns Some(task_address) if there was a valid clip mask.

fn get_prim_clip_task_and_texture( &self, clip_task_index: ClipTaskIndex, render_tasks: &RenderTaskGraph, ) -> Option<(RenderTaskAddress, TextureSource)>

Helper function to get the clip task address for a non-segmented primitive.
