Enum spade::PositionInTriangulation

pub enum PositionInTriangulation {
    OnVertex(FixedVertexHandle),
    OnEdge(FixedDirectedEdgeHandle),
    OnFace(FixedFaceHandle<InnerTag>),
    OutsideOfConvexHull(FixedDirectedEdgeHandle),
    NoTriangulation,
}

Describes a position in a triangulation.

The position is set in relation to the triangulation’s vertices, edges and faces. This type is usually the result of calling Triangulation::locate

Variants

OnVertex(FixedVertexHandle)

A position lies exactly on an existing vertex. The verticis handle is given.

OnEdge(FixedDirectedEdgeHandle)

A position lies exactly on an edge. The edge’s handle is given.

OnFace(FixedFaceHandle<InnerTag>)

A position lies in the interior of a face. The face’s handle is given.

OutsideOfConvexHull(FixedDirectedEdgeHandle)

A position lies outside the convex hull. The given edge handle refers to an edge of the convex hull which has both the point and the outer face on its left side.

Note: The given edge is not necessarily the closest edge to a position.

NoTriangulation

The triangulation contains either no vertices or exactly one vertex which has a different position than the query point.

Trait Implementations

impl Clone for PositionInTriangulation

fn clone(&self) -> PositionInTriangulation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PositionInTriangulation

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

Formats the value using the given formatter.

impl Hash for PositionInTriangulation

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PositionInTriangulation

fn cmp(&self, other: &PositionInTriangulation) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for PositionInTriangulation

fn eq(&self, other: &PositionInTriangulation) -> 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.

impl PartialOrd for PositionInTriangulation

fn partial_cmp(&self, other: &PositionInTriangulation) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
