Errors that can occur during representation theory computations

Representation theory involves constructing explicit matrices for group actions on vector spaces. Some representations require complex tensor product constructions that may not be implemented.

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.

UnsupportedRepresentation

The requested representation is not yet implemented

This occurs for higher-dimensional representations that require tensor product construction or other advanced techniques.

Fields

representation: String

Description of the representation (e.g., Dynkin labels)

reason: String

Reason why it’s not supported

InvalidParameters

Invalid representation parameters

For example, negative Dynkin labels or inconsistent dimensions.

Fields

description: String

Description of the invalid parameters

UnsupportedIntegrationMethod

Integration method not implemented for this group

Generic character integration requires group-specific Haar measure sampling, which must be implemented separately for each Lie group.

Fields

method: String

The integration method attempted

group: String

The group type (e.g., “generic LieGroup”)

suggestion: String

Suggested alternative

Trait Implementations

impl Clone for RepresentationError

fn clone(&self) -> RepresentationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RepresentationError

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

Formats the value using the given formatter.

impl Display for RepresentationError

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

Formats the value using the given formatter.

impl Error for RepresentationError

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 RepresentationError

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