Errors raised by the combinatorial-map core. Each variant names the specific invariant that was violated so callers can surface a precise diagnostic.

Variants

DartBufferTooSmall

darts buffer too small to hold the converted half-edges.

Fields

required: usize

HalfEdgeBufferTooSmall

half_edges buffer too small to hold the converted darts.

Fields

required: usize

DartOutOfRange

A β₁ or β₂ link points outside the dart array.

Fields

index: u32

Beta1Dangling

A β₁ link points to INVALID_INDEX mid-cycle (a dangling next pointer).

Fields

dart: u32

points_to: u32

Beta1NotPermutation

Following β₁ from dart did not return to dart within len hops — the permutation is malformed (not a finite cycle).

Fields

dart: u32

Beta2NotInvolution

β₂(β₂(d)) != d — the twin link is not an involution.

Fields

dart: u32

beta2: u32

beta2_beta2: u32

FaceInconsistent

Two darts in the same β₁-cycle carry different face fields.

Fields

dart: u32

face_a: u32

face_b: u32

OriginInconsistent

The origin connectivity invariant failed: origin(d) != origin(β₁(β₂(d))) for an interior dart.

Fields

dart: u32

expected: u32

found: u32

Trait Implementations

impl Clone for CMapError

fn clone(&self) -> CMapError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CMapError

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

Formats the value using the given formatter.

impl PartialEq for CMapError

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