Represents the possible errors that can occur during parsing of a logical expression.

Variants

ConditionParsing(E)

Represents an error that occurred while parsing a condition.

NoMatchingOpeningBracket

Represents an error when there is no matching opening bracket for a closing bracket.

NoMatchingClosingBracket

Represents an error when there is no matching closing bracket for an opening bracket.

MultipleOperators

Represents an error when there are multiple operators without a condition between them.

EmptyCondition

Represents an error when there is an empty condition.

LeadingOperator

Represents an error when there is a leading operator without a preceding condition.

TrailingOperator

Represents an error when therec is a trailing operator without a following condition.

ConditionBeforeOpeningBracket

Represents an error when there is a condition before an opening bracket.

ConditionAfterClosingBracket

Represents an error when there is a condition after a closing bracket.

Trait Implementations

impl<E: Clone> Clone for ParseError<E>

fn clone(&self) -> ParseError<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for ParseError<E>

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

Formats the value using the given formatter.

impl<E> Display for ParseError<E>

where E: Display,

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

Formats the value using the given formatter.

impl<E> Error for ParseError<E>

where Self: Debug + Display,

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<E> From<E> for ParseError<E>

fn from(err: E) -> Self

Converts to this type from the input type.

impl<E: PartialEq> PartialEq for ParseError<E>

fn eq(&self, other: &ParseError<E>) -> 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.

impl<E: Copy> Copy for ParseError<E>

impl<E: Eq> Eq for ParseError<E>

impl<E> StructuralPartialEq for ParseError<E>
