Struct OrientedSimplex 

pub struct OrientedSimplex {
    pub vertices: Vec<usize>,
}

Oriented simplex and its boundary operator.

An n-simplex [v_0, …, v_n] has boundary: ∂[v_0,…,v_n] = Σ_i (-1)^i [v_0,…,v̂_i,…,v_n].

Fields

vertices: Vec<usize>

Ordered list of vertex indices.

Implementations

impl OrientedSimplex

pub fn new(vertices: Vec<usize>) -> Self

Create an oriented simplex from a vertex list.

pub fn dim(&self) -> usize

Dimension of the simplex (n = #vertices - 1).

pub fn boundary(&self) -> Vec<(i32, Self)>

Compute the oriented boundary: list of (sign, face_simplex).

pub fn boundary_squared_zero(&self) -> bool

Check that ∂² = 0: applying boundary twice gives the zero chain.

Trait Implementations

impl Clone for OrientedSimplex

fn clone(&self) -> OrientedSimplex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OrientedSimplex

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

Formats the value using the given formatter.

impl PartialEq for OrientedSimplex

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