Enum iron_shapes::edge::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.

Trait Implementations

impl<IntersectionCoord: Clone, OriginalCoord: Clone, Edge: Clone> Clone for EdgeIntersection<IntersectionCoord, OriginalCoord, Edge>

fn clone(&self) -> EdgeIntersection<IntersectionCoord, OriginalCoord, Edge>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<IntersectionCoord: Debug, OriginalCoord: Debug, Edge: Debug> Debug for EdgeIntersection<IntersectionCoord, OriginalCoord, Edge>

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

Formats the value using the given formatter.

impl<IntersectionCoord: PartialEq, OriginalCoord: PartialEq, Edge: PartialEq> PartialEq for EdgeIntersection<IntersectionCoord, OriginalCoord, Edge>

fn eq( &self, other: &EdgeIntersection<IntersectionCoord, OriginalCoord, Edge>, ) -> 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.
