		Package loops contains ELK Layered 0.8.1's temporary self-loop model.
Package-Level Type Names (total 7)

	/* sort by: alphabet | popularity */
	 type Edge (struct)

		Fields (total 4)
			HyperLoop *HyperLoop
			LEdge layered.LEdgeID
			Source *Port
			Target *Port
		Methods (total 2)
			(*Edge) IsInline(arena *layered.LGraphArena) bool
				IsInline reports whether this self-loop edge has at least one inline label.
				ELK 0.11 uses the per-edge flag while routing opposing-side self loops.

			(*Edge) LabelSide() layered.PortSide
				LabelSide returns the aggregate side selected for this edge's hyper-loop.

Package-Level Functions (total 4)

	 func IndividualOrInherited(arena *layered.LGraphArena, nodeID layered.LNodeID, property basegraph.Property[float64]) float64
	 func Install(arena *layered.LGraphArena, nodeID layered.LNodeID) (*Holder, error)
	 func NeedsProcessing(arena *layered.LGraphArena, nodeID layered.LNodeID) bool
	 func TypeFromPortSides(sides [5]bool) (Type, error)
Package-Level Variables (only one)

	  var HolderProperty graph.Property[...]
		HolderProperty is InternalProperties.SELF_LOOP_HOLDER. Keeping the
		property here avoids making the shared layered package depend on an
		intermediate processor package.
