Enum SubdivisionError 

#[non_exhaustive]
pub enum SubdivisionError {
    NotATriangle {
        face: FaceId,
        degree: usize,
    },
    NotAQuad {
        face: FaceId,
        degree: usize,
    },
    BudgetExceeded {
        faces: usize,
        limit: usize,
    },
    Build(HalfedgeBuildError),
}

Why subdivision refused.

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.

NotATriangle

Loop subdivision needs triangles.

Fields

face: FaceId

The face.

degree: usize

Its number of sides.

NotAQuad

Catmull-Clark limit positions need quads (subdivide once first).

Fields

face: FaceId

The face.

degree: usize

Its number of sides.

BudgetExceeded

A level would produce more faces than allowed.

Fields

faces: usize

Faces the level would have.

limit: usize

The budget in force.

Build(HalfedgeBuildError)

Building a level’s mesh failed. Not expected: every level of a valid mesh is valid. Reported rather than unwrapped.

Trait Implementations

impl Clone for SubdivisionError

fn clone(&self) -> SubdivisionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SubdivisionError

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

Formats the value using the given formatter.

impl Display for SubdivisionError

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

Formats the value using the given formatter.

impl Error for SubdivisionError

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 From<HalfedgeBuildError> for SubdivisionError

fn from(source: HalfedgeBuildError) -> Self

Converts to this type from the input type.

impl PartialEq for SubdivisionError

fn eq(&self, other: &SubdivisionError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
