Enum EvaluationError 

pub enum EvaluationError<T: Display + PartialEq + Debug> {
    AtomicNotFound(T),
    ParameterNotFound(Parameter),
}

Evaluation error of an expression

Error that can occur during the evaluation of an expression in an environment.

Variants

AtomicNotFound(T)

Atomic was not found in the environment

ParameterNotFound(Parameter)

Parameter was not found in the environment

Trait Implementations

impl<T: Clone + Display + PartialEq + Debug> Clone for EvaluationError<T>

fn clone(&self) -> EvaluationError<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Display + PartialEq + Debug> Debug for EvaluationError<T>

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

Formats the value using the given formatter.

impl<T: Display + PartialEq + Debug> Display for EvaluationError<T>

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

Formats the value using the given formatter.

impl<T: Display + PartialEq + Debug> Error for EvaluationError<T>

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<EvaluationError<Location>> for PathBuilderError

fn from(err: EvaluationError<Location>) -> Self

Converts to this type from the input type.

impl From<EvaluationError<Parameter>> for PathBuilderError

fn from(err: EvaluationError<Parameter>) -> Self

Converts to this type from the input type.

impl From<EvaluationError<Variable>> for InvalidUpdateError

fn from(value: EvaluationError<Variable>) -> Self

Converts to this type from the input type.

impl From<EvaluationError<Variable>> for PathBuilderError

fn from(err: EvaluationError<Variable>) -> Self

Converts to this type from the input type.

impl<T: PartialEq + Display + PartialEq + Debug> PartialEq for EvaluationError<T>

fn eq(&self, other: &EvaluationError<T>) -> 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.
