BoxShadowDisplayItem
BuiltDisplayList

A display list.

BuiltDisplayListDescriptor

Describes the memory layout of a display list.

BuiltDisplayListIter
ClipAndScrollInfo
ClipDisplayItem
ColorF

Represents RGBA screen colors with floating point numbers.

ColorU

Represents RGBA screen colors with one byte per channel.

ComplexClipRegion
DevicePixel

Geometry in the coordinate system of the render target (screen or intermediate surface) in physical pixels.

DisplayItemRef
DisplayListBuilder
DocumentId
DynamicProperties

When using generate_frame(), a list of PropertyValue structures can optionally be supplied to provide the current value of any animated properties.

Epoch
ExternalEvent

An opaque pointer-sized value.

ExternalImageData
ExternalImageId

An arbitrary identifier for an external image provided by the application. It must be a unique identifier for each external image.

FontVariation
GenericDisplayItem

The DI is generic over the specifics, while allows to use the "complete" version of it for convenient serialization.

LayerPixel

Geometry in a layer's local coordinate space (logical pixels).

LineDisplayItem
NativeFontHandle
NinePatchDescriptor
NormalBorder
PipelineId

From the point of view of WR, PipelineId is completely opaque and generic as long as it's clonable, serializable, comparable, and hashable.

PremultipliedColorF

Represents pre-multiplied RGBA colors with floating point numbers.

PrimitiveInfo
PropertyBindingId
PropertyBindingKey

A unique key that is used for connecting animated property values to bindings in the display list.

PropertyValue

The current value of an animated property. This is supplied by the calling code.

ResourceId
ResourceUpdates

The resource updates for a given transaction (they must be applied in the same frame).

SaveState
ScrollFrameDisplayItem
ScrollLayerPixel

Geometry in a layer's scrollable parent coordinate space (logical pixels).

ScrollLayerState
Shadow
StackingContext
StickyFrameDisplayItem
StickyOffsetBounds

The minimum and maximum allowable offset for a sticky frame in a single dimension.

TextDisplayItem
Tiles

Offset in number of tiles.

UpdateImage
WorldPixel

Geometry in the document's coordinate space (logical pixels).

YuvImageDisplayItem
ZoomFactor

Represents a zoom factor.

A binding property can either be a specific value (the normal, non-animated case) or point to a binding location to fetch the current value from.

Type Definitions

BlobImageData
BlobImageResult
DeviceIntLength
DeviceIntPoint
DeviceIntRect
DeviceIntSize
DevicePixelScale

Scaling ratio from world pixels to device pixels.

DevicePoint
DeviceRect
DeviceSize
DeviceUintPoint
DeviceUintRect
DeviceUintSize
DeviceVector2D
DisplayItem
DocumentLayer

Documents are rendered in the ascending order of their associated layer values.

GlyphIndex
ItemTag

A tag that can be used to identify items during hit testing. If the tag is missing then the item doesn't take part in hit testing at all. This is composed of two numbers. In Servo, the first is an identifier while the second is used to select the cursor that should be used during mouse movement. In Gecko, the first is a scrollframe identifier, while the second is used to store various flags that APZ needs to properly process input events.

LayerPoint
LayerPoint3D
LayerPointAu
LayerPrimitiveInfo
LayerRect
LayerRectAu
LayerSize
LayerSizeAu
LayerToScrollTransform
LayerToWorldScale

Scaling ratio from layer to world. Used for cases where we know the layer is in world space, or specifically want to treat it this way.

LayerToWorldTransform
LayerTransform
LayerVector2D
LayerVector3D
LayoutPixel

Geometry in a stacking context's local coordinate space (logical pixels).

LayoutPoint
LayoutPrimitiveInfo
LayoutRect
LayoutSize
LayoutTransform
LayoutVector2D
LayoutVector3D
PipelineSourceId

This type carries no valuable semantics for WR. However, it reflects the fact that clients (Servo) may generate pipelines by different semi-independent sources. These pipelines still belong to the same IdNamespace and the same DocumentId. Having this extra Id field enables them to generate PipelineId without collision.
