Crate jellyflow_layout 

Optional headless layout adapters for Jellyflow.

This crate keeps automatic layout outside the core document model. Layout engines receive a projection of a Jellyflow graph and return normal [GraphTransaction] values that hosts can apply explicitly.

Structs

DugongLayoutEngine

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

LayoutContext

Runtime or host-owned context available to layout engines.

LayoutEdgeRoute

A layout-produced edge route.

LayoutEngineId

Stable identifier for a layout engine.

LayoutEngineMetadata

Discovery metadata for one layout engine.

LayoutEngineRegistry

Caller-owned registry of layout engines.

LayoutEngineRequest

Request for one selected layout engine.

LayoutFamilyId

Stable identifier for a layout engine family.

LayoutFamilyMetadata

Metadata for a group of layout engines with related behavior.

LayoutNodePosition

A node position produced by a layout run.

LayoutOptions

Options shared by Jellyflow layout adapters.

LayoutPresetBuilder

Builder for common layout presets.

LayoutRequest

A headless layout request.

LayoutResult

Result of a headless layout run.

LayoutSpacing

Spacing knobs passed through to layout engines that support layered spacing.

MindMapFreeformLayoutEngine

Built-in freeform mind-map engine that only resolves overlaps.

MindMapRadialLayoutEngine

Built-in radial mind-map engine.

TidyTreeLayoutEngine

Built-in tidy tree layout engine.

Enums

Public capabilities hosts can use when choosing a layout engine.

LayoutError

Errors reported by layout projection, registry lookup, or layout output conversion.
