Enum ncollide3d::shape::FeatureId

pub enum FeatureId {
    Vertex(usize),
    Edge(usize),
    Face(usize),
    Unknown,
}

An identifier of a feature of a convex polyhedron.

This identifier is shape-dependent and is seach that it allows an efficient retrieval of the geometric information of the feature.

Variants

Vertex(usize)

Shape-dependent identifier of a vertex.

Edge(usize)

Shape-dependent identifier of an edge.

Face(usize)

Shape-dependent identifier of a face.

Unknown

Unknown identifier.

Methods

impl FeatureId

pub fn unwrap_vertex(self) -> usize

Revries the value of the identifier if self is a vertex.

pub fn unwrap_edge(self) -> usize

Revries the value of the identifier if self is an edge.

pub fn unwrap_face(self) -> usize

Revries the value of the identifier if self is a face.

Trait Implementations

impl Copy for FeatureId

impl Clone for FeatureId

fn clone(&self) -> FeatureId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FeatureId

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

Formats the value using the given formatter.

impl Hash for FeatureId

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,

Feeds a slice of this type into the given [Hasher].

impl PartialEq for FeatureId

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

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

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

This method tests for !=.
