Enum RevisionError 

pub enum RevisionError {
    BeliefNotFound(String),
    MaxBeliefsExceeded,
    ContradictionDetected {
        new: String,
        existing: String,
    },
    RevisionFailed(String),
}

Errors returned by BeliefRevisionEngine operations.

Variants

BeliefNotFound(String)

A referenced belief ID does not exist in the set.

MaxBeliefsExceeded

Adding the belief would exceed max_beliefs.

ContradictionDetected

The new belief directly contradicts an existing one.

Fields

new: String

Formula of the new / incoming belief.

existing: String

Formula of the existing / conflicting belief.

RevisionFailed(String)

Revision failed for an unspecified reason.

Trait Implementations

impl Clone for RevisionError

fn clone(&self) -> RevisionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RevisionError

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

Formats the value using the given formatter.

impl Display for RevisionError

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

Formats the value using the given formatter.

impl Error for RevisionError

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 RevisionError

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