pub enum ParseError<T: Eval> {
    LiteralParseError(T::ErrParse),
    SyntaxError(SyntaxError),
}

Variants

LiteralParseError(T::ErrParse)

An error that occurred while calling the literal’s own parse function.

SyntaxError(SyntaxError)

See SyntaxError.

Trait Implementations

impl<T: Debug + Eval> Debug for ParseError<T>

where T::ErrParse: Debug,

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

Formats the value using the given formatter.

impl<T: Eval> Display for ParseError<T>

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

Formats the value using the given formatter.

impl<T: Eval> Error for ParseError<T>

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<T: Eval> From<Error<Rule>> for ParseError<T>

fn from(value: Error<Rule>) -> Self

Converts to this type from the input type.

impl<T: Eval> From<ParseError<T>> for EvalError<T>

fn from(source: ParseError<T>) -> Self

Converts to this type from the input type.

impl<T: Eval> From<SyntaxError> for ParseError<T>

fn from(source: SyntaxError) -> Self

Converts to this type from the input type.

impl<T: PartialEq + Eval> PartialEq for ParseError<T>

where T::ErrParse: PartialEq,

fn eq(&self, other: &ParseError<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.
