Enum libreda_db::prelude::EdgeIntersection

pub enum EdgeIntersection<IntersectionCoord, OriginalCoord, Edge> {
    None,
    Point(Point<IntersectionCoord>),
    EndPoint(Point<OriginalCoord>),
    Overlap(Edge),
}

Return type for the edge-edge intersection functions. Stores all possible results of an edge to edge intersection.

Note on coordinate types:

There are two coordinate types (which may be the same concrete type):

• OriginalCoord is the coordinate type used to define the edge end-points. An intersection at the end-points can be expressed with this coordinate type.
• IntersectionCoord is the coordinate type used to express intersection points somewhere in the middle of the edge. This may differ from the coordinate type of the end-points. For example if the end-points are stored in integer coordinates the intersection may require rational coordinates. But in special cases such as axis-aligned edges, the intersection point can indeed be expressed in integer coordinates.

Variants

None

No intersection.

Point(Point<IntersectionCoord>)

Intersection in a single point but not on an endpoint of an edge.

EndPoint(Point<OriginalCoord>)

Intersection in an endpoint of an edge.

Overlap(Edge)

Full or partial overlap.
