Module layout 

Headless automatic layout integration.

This module is a thin runtime facade over jellyflow-layout: it turns a layout request into a normal graph transaction, then lets the store’s dispatch/profile pipeline apply it.

Structs

DugongLayoutApplyOutcome

Result of applying a dugong layout through the store.

DugongLayoutEngine

Built-in Dagre-compatible layout engine powered by dugong.

LayoutApplyOutcome

Result of applying a layout engine through the store.

LayoutContext

Runtime or host-owned context available to layout engines.

LayoutEdgeRoute

A layout-produced edge route.

LayoutEngineId

Stable identifier for a layout engine.

LayoutEngineMetadata

Functions

apply_dugong_layout

Runs dugong layout and commits the resulting transaction through normal store dispatch.
