Struct CellArray 

pub struct CellArray { /* private fields */ }

Storage for cell topology using offsets + connectivity arrays. Uses Arc<Vec> for zero-copy clone with copy-on-write semantics.

Implementations

impl CellArray

pub fn new() -> Self

pub fn from_raw(offsets: Vec<i64>, connectivity: Vec<i64>) -> Self

Create a CellArray from raw offsets and connectivity.

pub fn from_triangles(tris: &[[i64; 3]]) -> Self

Create a CellArray from triangle index arrays.

pub fn from_quads(quads: &[[i64; 4]]) -> Self

Create a CellArray from quad index arrays.

pub fn push_cell(&mut self, point_ids: &[i64])

Append a cell with the given point indices.

pub fn num_cells(&self) -> usize

pub fn cell(&self, idx: usize) -> &[i64]

Returns the point indices for cell idx.

pub fn is_empty(&self) -> bool

pub fn offsets(&self) -> &[i64]

pub fn connectivity(&self) -> &[i64]

pub fn connectivity_len(&self) -> usize

Total number of point index entries across all cells.

pub fn clear(&mut self)

pub fn cell_size(&self, idx: usize) -> usize

Get the number of points in cell at idx.

pub fn cell_sizes(&self) -> impl Iterator<Item = usize> + '_

Iterator over cell sizes (number of points per cell).

pub fn max_cell_size(&self) -> usize

Maximum cell size (max number of points in any cell).

pub fn is_homogeneous(&self) -> Option<usize>

Check if all cells have the same size.

pub fn iter(&self) -> CellIter<'_>

Iterate over cells, yielding a slice of point indices for each.

Trait Implementations

impl Clone for CellArray

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CellArray

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

Formats the value using the given formatter.

impl Default for CellArray

fn default() -> Self

Returns the “default value” for a type.

impl<'a> IntoIterator for &'a CellArray

type Item = &'a [i64]

The type of the elements being iterated over.

type IntoIter = CellIter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for CellArray

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