Enum TopologyError

#[non_exhaustive]
pub enum TopologyError {
    IndexOutOfRange {
        triangle: usize,
        vertex: u32,
        vertices: usize,
    },
    DegenerateTriangle {
        triangle: usize,
    },
    NonManifold {
        edges: usize,
        vertices: usize,
    },
}

Why a mesh’s topology could not be classified.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

IndexOutOfRange

A triangle names a vertex the mesh does not have.

Fields

triangle: usize

The offending triangle.

vertex: u32

The index it names.

vertices: usize

How many positions the mesh has.

DegenerateTriangle

A triangle repeats a vertex, so it has no edges of its own.

Fields

triangle: usize

The offending triangle.

NonManifold

The mesh is not a two-manifold.

Fields

edges: usize

Edges used by three or more triangles.

vertices: usize

Vertices whose incident triangles form more than one fan.

Trait Implementations

impl Clone for TopologyError

fn clone(&self) -> TopologyError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TopologyError

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

Formats the value using the given formatter.

impl Display for TopologyError

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

Formats the value using the given formatter.

impl Error for TopologyError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for TopologyError

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