Enum libreda_pnr::db::RLineIntersection[][src]

pub enum RLineIntersection<T> where
    T: CoordinateType
{ None, Point(Point<T>), Collinear, }
Expand description

Return type for the line-line intersection functions. Stores all possible results of a line to line intersection.

Variants

None

No intersection at all.

Point(Point<T>)

Intersection in a single point. Besides the intersection point also an other expression for the intersection point is given. The three values (a, b, c) describe the intersection point in terms of a starting point (the starting point of the edge which defines the line) and the direction of the edge multiplied by a fraction.

edge.start + edge.vector()*a/c == p and other_edge.start + other_edge.vector()*b/c == p.

Tuple Fields of Point

0: Point<T>
Collinear

Lines are collinear.
