Enum RestrictedExpressionError 

pub enum RestrictedExpressionError {
    InvalidRestrictedExpression {
        feature: String,
    },
}

Errors generated in the restricted_expr module

Variants

InvalidRestrictedExpression

A “restricted” expression contained a feature that is not allowed in “restricted” expressions. The feature is just a string description of the feature that is not allowed.

Fields

feature: String

what disallowed feature appeared in the expression

Trait Implementations

impl Clone for RestrictedExpressionError

fn clone(&self) -> RestrictedExpressionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RestrictedExpressionError

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

Formats the value using the given formatter.

impl Display for RestrictedExpressionError

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

Formats the value using the given formatter.

impl Error for RestrictedExpressionError

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<RestrictedExpressionError> for EvaluationError

fn from(source: RestrictedExpressionError) -> Self

Converts to this type from the input type.

impl From<RestrictedExpressionError> for JsonDeserializationError

fn from(source: RestrictedExpressionError) -> Self

Converts to this type from the input type.

impl From<RestrictedExpressionError> for ParseError

fn from(source: RestrictedExpressionError) -> Self

Converts to this type from the input type.

impl Hash for RestrictedExpressionError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RestrictedExpressionError

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