Struct webrender::picture::PrimitiveList

pub struct PrimitiveList {
    pub clusters: Vec<PrimitiveCluster>,
    pub child_pictures: Vec<PictureIndex>,
    pub image_surface_count: usize,
    pub yuv_image_surface_count: usize,
    pub needs_scissor_rect: bool,
}

A list of primitive instances that are added to a picture This ensures we can keep a list of primitives that are pictures, for a fast initial traversal of the picture tree without walking the instance list.

Fields

clusters: Vec<PrimitiveCluster>

List of primitives grouped into clusters.

child_pictures: Vec<PictureIndex>

image_surface_count: usize

The number of Image compositor surfaces that were found when adding prims to this list, which might be rendered as overlays.

yuv_image_surface_count: usize

The number of YuvImage compositor surfaces that were found when adding prims to this list, which might be rendered as overlays.

needs_scissor_rect: bool

Implementations

impl PrimitiveList

pub fn empty() -> Self

Construct an empty primitive list. This is just used during the take_context / restore_context borrow check dance, which will be removed as the picture traversal pass is completed.

pub fn merge(&mut self, other: PrimitiveList)

pub fn add_prim( &mut self, prim_instance: PrimitiveInstance, prim_rect: LayoutRect, spatial_node_index: SpatialNodeIndex, prim_flags: PrimitiveFlags, prim_instances: &mut Vec<PrimitiveInstance>, clip_tree_builder: &ClipTreeBuilder, )

Add a primitive instance to the end of the list

pub fn is_empty(&self) -> bool

Returns true if there are no clusters (and thus primitives)

Trait Implementations

impl Serialize for PrimitiveList

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
