Module layout 

Modules

coordinator

Node coordinator system mirroring Jetpack Compose’s NodeCoordinator pattern.

core

policies

Structs

LayoutBox

Layout information for a single node.

LayoutMeasurements

Result of running the measure pass for a Compose layout tree.

LayoutNodeData

Snapshot of the data required to render a layout node.

LayoutTree

Result of running layout for a Compose tree.

MeasureLayoutOptions

SemanticsCallback

Discrete event callback reference produced during semantics extraction.

SemanticsNode

A single node within the semantics tree.

SemanticsTree

Rooted semantics tree extracted after layout.

Enums

LayoutNodeKind

Classification of the node captured inside a LayoutBox.

SemanticsAction

Semantics action exposed to the input system.

SemanticsRole

Semantic role describing how a node should participate in accessibility and hit testing. Roles are now derived from SemanticsConfiguration rather than widget types.

Traits

LayoutEngine

Extension trait that equips MemoryApplier with layout computation.

Functions

build_semantics_tree_from_layout_tree

Builds a semantics tree from an existing LayoutTree.

measure_layout

Runs the measure phase for the subtree rooted at root.

measure_layout_with_options

tree_needs_layout

Check if a node or any of its descendants needs measure (selective measure optimization). This can be used by the app shell to skip layout when the tree is clean.

tree_needs_semantics

Check if the root semantics snapshot is dirty.
