Enum DecError 

pub enum DecError {
    EmptyMesh,
    IndexOutOfBounds {
        index: usize,
        len: usize,
    },
    NotWellCentered {

    SingularLaplacian,
    FieldLengthMismatch {
        expected: usize,

    },
    LinearAlgebra(String),
}

Errors that can occur in discrete exterior calculus operations.

Variants

EmptyMesh

The mesh has no vertices, edges, or triangles.

IndexOutOfBounds

A simplex index is out of bounds.

Fields

index: usize

len: usize

NotWellCentered

A mesh is not well-centered (a circumcenter lies outside its simplex). This causes the Hodge star to have negative weights, breaking SPD.

Fields

simplex: usize

volume: f64

SingularLaplacian

The Laplacian matrix is singular (expected for closed manifolds without boundary conditions; caller should use a pseudoinverse or add a pin constraint).

FieldLengthMismatch

A field has the wrong number of components for this mesh.

Fields

expected: usize

got: usize

LinearAlgebra(String)

Linear algebra error (e.g., Cholesky failed on non-SPD matrix).

Trait Implementations

impl Debug for DecError

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

Formats the value using the given formatter.

impl Display for DecError

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

Formats the value using the given formatter.

impl Error for DecError

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.
