Enum VertexAnchor

pub enum VertexAnchor {
    Node(NodeIdType),
    Curve(CurveIdType),
    Surface(SurfaceIdType),
    Body(BodyIdType),
}

Geometrical mesh anchor.

This enum is used as an attribute to link mesh vertices to entities of the represented geometry.

The AttributeUpdate implementation is used to enforce the dimensional conditions required to merge two anchors. The merge-ability of two anchors also depends on their intersection; we expect this to be handled outside of the merge functor, as doing it inside would require leaking map data into the trait’s methods.

Variants

Node(NodeIdType)

Vertex is linked to a node.

Curve(CurveIdType)

Vertex is linked to a curve.

Surface(SurfaceIdType)

Vertex is linked to a surface.

Body(BodyIdType)

Vertex is linked to a 3D body.

Trait Implementations

impl AttributeBind for VertexAnchor

const BIND_POLICY: OrbitPolicy = OrbitPolicy::Vertex

[OrbitPolicy] determining the kind of topological entity to which the attribute is associated.

type StorageType = AttrSparseVec<VertexAnchor>

Storage type used for the attribute.

type IdentifierType = u32

Identifier type of the entity the attribute is bound to.

impl AttributeUpdate for VertexAnchor

fn merge(attr1: Self, attr2: Self) -> Result<Self, AttributeError>

Merging routine, i.e. how to obtain a new value from two existing ones.

fn split(attr: Self) -> Result<(Self, Self), AttributeError>

Splitting routine, i.e. how to obtain the two new values from a single one.

fn merge_incomplete(_: Self) -> Result<Self, AttributeError>

Fallback merging routine, i.e. how to obtain a new value from a single existing one.

fn merge_from_none() -> Result<Self, AttributeError>

Fallback merging routine, i.e. how to obtain a new value from no existing one.

fn split_from_none() -> Result<(Self, Self), AttributeError>

Fallback splitting routine, i.e. how to obtain two new values from no existing one.

impl Clone for VertexAnchor

fn clone(&self) -> VertexAnchor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VertexAnchor

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

Formats the value using the given formatter.

impl Hash for VertexAnchor

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 PartialEq for VertexAnchor

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