Enum ClipSpaceConversion 

pub enum ClipSpaceConversion {
    Local,
    ScaleOffset(ScaleOffset),
    Transform(LayoutToVisTransform),
}

A helper struct for converting between coordinate systems of clip sources and primitives.

Note that the variants don’t represent the same transformation because depending on the situation we either map between the clip and primitive spaces or project them both to visibility space.

Variants

Local

The clip and the clipped primitive are in the same coordinate space.

ScaleOffset(ScaleOffset)

The clip and the clipped primitive are in the same coordinate system.

This variant represents the transform from the clip’s local space to the clipped primitive’s local space.

Transform(LayoutToVisTransform)

The clip and the clipped primitive are in different coordinate system.

This Variant represents the transform from the clip’s local space to the visibility space.

Implementations

impl ClipSpaceConversion

pub fn new( prim_spatial_node_index: SpatialNodeIndex, clip_spatial_node_index: SpatialNodeIndex, visibility_spatial_node_index: SpatialNodeIndex, spatial_tree: &SpatialTree, ) -> Self

Construct a new clip space converter between two spatial nodes.

fn to_flags(&self) -> ClipNodeFlags

Trait Implementations

impl Debug for ClipSpaceConversion

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl MallocSizeOf for ClipSpaceConversion

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 ClipSpaceConversion

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
