Errors related to the Deontic Inference process within the Effect Ethos.

Variants

FailedToAddTeloid

Failed to add a new teloid to the graph.

FailedToAddEdge(usize, usize)

Failed to add edge to the graph.

GraphNotFrozen

An operation was attempted on a graph that was not frozen. Deontic inference requires a static, immutable graph.

GraphIsFrozen

An mutation operation was attempted on a graph that was frozen. Mutation requires an unfrozen graph

GraphIsCyclic

The TeloidGraph is invalid because it contains a cycle, which would lead to infinite loops in reasoning.

TeloidNotFound

A TeloidID exists in the graph or tag index but not in the TeloidStore, indicating a critical state inconsistency.

Fields

id: TeloidID

InconclusiveVerdict

The final set of active norms was empty or otherwise unable to produce a conclusive verdict.

NoRelevantNormsFound

No applicable norms were found for a given action.

MissingContext

The CausalState is missing a context, which is required for deontic evaluation.

GraphError(GraphError)

Wraps a lower-level error from the ultragraph crate.

Trait Implementations

impl Clone for DeonticError

fn clone(&self) -> DeonticError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeonticError

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

Formats the value using the given formatter.

impl Display for DeonticError

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

Formats the value using the given formatter.

impl Error for DeonticError

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<GraphError> for DeonticError

fn from(err: GraphError) -> Self

Converts to this type from the input type.

impl PartialEq for DeonticError

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