Enum iron_shapes::edge::LineIntersection

pub enum LineIntersection<TP: CoordinateType, TE: CoordinateType> {
    None,
    Point(Point<TP>, (TE, TE, TE)),
    Collinear,
}

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<TP>, (TE, TE, TE))

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.

Collinear

Lines are collinear.

Trait Implementations

impl<TP: Clone + CoordinateType, TE: Clone + CoordinateType> Clone for LineIntersection<TP, TE>

fn clone(&self) -> LineIntersection<TP, TE>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<TP: Debug + CoordinateType, TE: Debug + CoordinateType> Debug for LineIntersection<TP, TE>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<TP: PartialEq + CoordinateType, TE: PartialEq + CoordinateType> PartialEq for LineIntersection<TP, TE>

fn eq(&self, other: &LineIntersection<TP, TE>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
