Implementations

impl ClipStore

pub fn new() -> Self

pub fn get_instance_from_range( &self, node_range: &ClipNodeRange, index: u32 ) -> &ClipNodeInstance

pub fn set_active_clips( &mut self, prim_spatial_node_index: SpatialNodeIndex, pic_spatial_node_index: SpatialNodeIndex, clip_leaf_id: ClipLeafId, spatial_tree: &SpatialTree, clip_data_store: &DataStore<ClipIntern>, clip_tree: &ClipTree )

Setup the active clip chains for building a clip chain instance.

pub fn set_active_clips_from_clip_chain( &mut self, prim_clip_chain: &ClipChainInstance, prim_spatial_node_index: SpatialNodeIndex, spatial_tree: &SpatialTree, clip_data_store: &DataStore<ClipIntern> )

Setup the active clip chains, based on an existing primitive clip chain instance.

pub fn get_inner_rect_for_clip_chain( &self, clip_chain: &ClipChainInstance, clip_data_store: &DataStore<ClipIntern>, spatial_tree: &SpatialTree ) -> Option<PictureRect>

Given a clip-chain instance, return a safe rect within the visible region that can be assumed to be unaffected by clip radii. Returns None if it encounters any complex cases, just handling rounded rects in the same coordinate system as the clip-chain for now.

pub fn build_clip_chain_instance( &mut self, local_prim_rect: LayoutRect, prim_to_pic_mapper: &SpaceMapper<LayoutPixel, PicturePixel>, pic_to_world_mapper: &SpaceMapper<PicturePixel, WorldPixel>, spatial_tree: &SpatialTree, gpu_cache: &mut GpuCache, resource_cache: &mut ResourceCache, device_pixel_scale: DevicePixelScale, world_rect: &WorldRect, clip_data_store: &mut DataStore<ClipIntern>, rg_builder: &mut RenderTaskGraphBuilder, request_resources: bool ) -> Option<ClipChainInstance>

The main interface external code uses. Given a local primitive, positioning information, and a clip chain id, build an optimized clip chain instance.

pub fn begin_frame(&mut self, scratch: &mut ClipStoreScratchBuffer)

pub fn end_frame(&mut self, scratch: &mut ClipStoreScratchBuffer)

pub fn visible_mask_tiles( &self, instance: &ClipNodeInstance ) -> &[VisibleMaskImageTile]

Trait Implementations

impl MallocSizeOf for ClipStore

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl Serialize for ClipStore

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
