Errors that can arise when building or using cellular sheaves.

Variants

DimensionMismatch

A restriction map dimension does not match its target stalk.

Fields

edge: (usize, usize)

expected_rows: usize

expected_cols: usize

got_rows: usize

got_cols: usize

InvalidNode(usize)

A node index is out of range.

InvalidEdge(usize, usize)

An edge references an unknown node.

BeliefDimensionMismatch

Belief vector length does not match stalk dimension.

Fields

agent: String

expected: usize

got: usize

EmptySheaf

Empty sheaf (no nodes).

SingularMatrix

Linear algebra failure.

Trait Implementations

impl Debug for SheafError

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

Formats the value using the given formatter.

impl Display for SheafError

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

Formats the value using the given formatter.

impl Error for SheafError

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.
