Enum TopologyEvent 

pub enum TopologyEvent {
    NodeAdded(NodeSnapshot),
    NodeRemoved(NodeId),
    LinkAdded(SnapshotEdge),
    LinkRemoved(LinkId),
    GraphCompiled,
    GraphReset,
}

Available on crate feature topology only.

An observable change to a graph’s topology.

Emitted on the non-RT mutation path (e.g. from add_node / link) and delivered to subscribers registered via Graph::subscribe_topology. The RT Graph::process_cycle path never emits events.

Variants

NodeAdded(NodeSnapshot)

A node was added; carries its structural snapshot.

NodeRemoved(NodeId)

A node was removed; carries its id.

LinkAdded(SnapshotEdge)

A link was added; carries the edge.

LinkRemoved(LinkId)

A link was removed; carries its id.

GraphCompiled

The graph finished compiling (topological sort + scratch allocation).

GraphReset

The graph was reset to an uncompiled state.
