Crate layout_api

This module contains traits in script used generically in the rest of Servo. The traits are here instead of in script so that these modules won’t have to depend on script.

Modules

layout_damage 🔒

wrapper_traits

Structs

DomParallelInfo

Information that we need stored in each DOM node.

ElementsFromPointFlags

ElementsFromPointResult

Describe an item that matched a hit-test query.

HTMLCanvasData

HTMLMediaData

IFrameSize

ImageAnimationState

LayoutConfig

LayoutDamage

Individual layout actions that may be necessary after restyling. This is an extension of RestyleDamage from stylo, which only uses the 4 lower bits.

MediaFrame

MediaMetadata

OffsetParentResponse

PendingImage

The data associated with an image that is not yet present in the image cache. Used by the script thread to hold on to DOM elements that need to be repainted when an image fetch is complete.

PendingRasterizationImage

A data structure to tarck vector image that are fully loaded (i.e has a parsed SVG tree) but not yet rasterized to the size needed by layout. The rasterization is happening in the image cache.

PendingRestyle

A pending restyle.

PropertyRegistration

ReflowPhasesRun

The phases of reflow that were run when processing a reflow in layout.

ReflowRequest

Information needed for a script-initiated reflow.

ReflowRequestRestyle

Information needed for a script-initiated reflow that requires a restyle and reconstruction of box and fragment trees.

ReflowResult

Information derived from a layout pass that needs to be returned to the script thread.

RestyleReason

Conditions which cause a [Document] to need to be restyled during reflow, which might cause the rest of layout to happen as well.

SVGElementData

StyleData

TrustedNodeAddress

The address of a node known to be valid. These are sent from script to layout.

Enums

BoxAreaType

Type of the area of CSS box for query. See https://www.w3.org/TR/css-box-3/#box-model.

FragmentType

The type of fragment that a scroll root is created for.

LayoutElementType

LayoutImageDestination

The destination in layout where an image is needed.

LayoutNodeType

PendingImageState

Whether the pending image needs to be fetched or is waiting on an existing fetch.

QueryMsg

ReflowGoal

The goal of a reflow request.

RegisterPropertyError

ScrollContainerQueryType

ScrollContainerResponse

Constants

SPECIAL_SCROLL_ROOT_ID_MASK 🔒

If none of the bits outside this mask are set, the scroll root is a special scroll root. Note that we assume that the top 16 bits of the address space are unused on the platform.

Statics

NEXT_SPECIAL_SCROLL_ROOT_ID 🔒

The next ID that will be used for a special scroll root id.

Traits

GenericLayoutDataTrait

Layout

LayoutFactory

ScriptThreadFactory

This trait is part of layout_api because it depends on both script_traits and also LayoutFactory from this crate. If it was in script_traits there would be a circular dependency.

Functions

combine_id_with_fragment_type

next_special_id 🔒

Returns a new scroll root ID for a scroll root.

node_id_from_scroll_id

Type Aliases

GenericLayoutData

IFrameSizes
