Enum Intersection

pub enum Intersection<'a, V, DE, UE, F>
where
    V: HasPosition,
{
    EdgeIntersection(DirectedEdgeHandle<'a, V, DE, UE, F>),
    VertexIntersection(VertexHandle<'a, V, DE, UE, F>),
    EdgeOverlap(DirectedEdgeHandle<'a, V, DE, UE, F>),
}

An intersection that can occur when moving through a triangulation along a straight line.

This is used as return type for LineIntersectionIterator.

Variants

EdgeIntersection(DirectedEdgeHandle<'a, V, DE, UE, F>)

Indicates that the line is either crossing or touching an existing edge. The line’s destination will always be either on the edge or on its left side (in a right-handed coordinate system).

VertexIntersection(VertexHandle<'a, V, DE, UE, F>)

Indicates that the line is touching a vertex. A line beginning or starting on a vertex also generates this intersection. A “line” beginning and starting on the same vertex will also return this intersection.

EdgeOverlap(DirectedEdgeHandle<'a, V, DE, UE, F>)

Indicates that a line is (partially) overlapping an existing edge.

This implies that the line points in the same direction as the edge and that they share a common line segment.

Implementations

impl<'a, V, DE, UE, F> Intersection<'a, V, DE, UE, F>

where V: HasPosition,

pub fn as_edge_intersection( &self, ) -> Option<DirectedEdgeHandle<'a, V, DE, UE, F>>

Returns the intersected edge if this is an edge intersection or None otherwise.

Trait Implementations

impl<V, DE, UE, F> Clone for Intersection<'_, V, DE, UE, F>

where V: HasPosition,

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<V, DE, UE, F> Debug for Intersection<'_, V, DE, UE, F>

where V: HasPosition,

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

Formats the value using the given formatter.

impl<V, DE, UE, F> PartialEq for Intersection<'_, V, DE, UE, F>

where V: HasPosition,

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl<V, DE, UE, F> Copy for Intersection<'_, V, DE, UE, F>

where V: HasPosition,
