Struct CwCell 

pub struct CwCell {
    pub id: usize,
    pub dim: usize,
    pub label: String,
    pub coords: Option<[f64; 3]>,
    pub boundary: Vec<usize>,
    pub boundary_signs: Vec<i32>,
}

A single cell in a CW complex of dimension dim.

A 0-cell is a vertex, a 1-cell is an edge, a 2-cell is a face, etc.

Fields

id: usize

Unique cell identifier.

dim: usize

Cell dimension.

label: String

Label / name (optional).

coords: Option<[f64; 3]>

Vertex coordinates for 0-cells (ignored for higher cells).

boundary: Vec<usize>

Indices of the boundary cells (cells of dimension dim-1).

boundary_signs: Vec<i32>

Incidence signs (+1 or −1) corresponding to each boundary cell.

Implementations

impl CwCell

pub fn vertex(id: usize, coords: [f64; 3]) -> Self

Create a 0-cell (vertex) with coordinates.

pub fn edge(id: usize, from: usize, to: usize) -> Self

Create a 1-cell (edge) between vertex from and vertex to.

pub fn face(id: usize, boundary_edges: Vec<usize>, signs: Vec<i32>) -> Self

Create a 2-cell (face) with an ordered list of boundary edges and signs.

pub fn n_cell( id: usize, dim: usize, boundary: Vec<usize>, signs: Vec<i32>, ) -> Self

Create a general n-cell.

pub fn is_vertex(&self) -> bool

Whether this cell is a vertex.

pub fn is_edge(&self) -> bool

Whether this cell is an edge.

pub fn is_face(&self) -> bool

Whether this cell is a face.

Trait Implementations

impl Clone for CwCell

fn clone(&self) -> CwCell

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CwCell

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

Formats the value using the given formatter.

impl PartialEq for CwCell

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