Package-Level Functions (total 3)

func IsLifelineEnd(obj *d2graph.Object) bool IsLifelineEnd reports whether obj is a synthetic sequence-diagram lifeline endpoint.

func Layout(ctx context.Context, g *d2graph.Graph, layout d2graph.LayoutGraph) error Layout runs the sequence diagram layout engine on objects of shape sequence_diagram 1. Run layout on sequence diagrams 2. Set the resulting dimensions to the main graph shape

func LifelineEndID(actorID string) string LifelineEndID returns the synthetic endpoint ID for an actor's lifeline. The hash is formatted as an unsigned 32-bit value so the ID is stable across architectures.
