Enum TraceResult 

pub enum TraceResult {
    Clear(Vec2),
    SnappedToNode(NodeId),
    SnappedToEdge {
        edge_id: EdgeId,
        intersection_pos: Vec2,
    },
}

Result of evaluating a proposed trace step against the existing graph.

Variants

Clear(Vec2)

Path is clear — create a new node at this position.

SnappedToNode(NodeId)

Landed near an existing intersection — snap to it.

SnappedToEdge

Hit or landed near an existing edge — split it to form an intersection.

Fields

edge_id: EdgeId

intersection_pos: Vec2
