pub enum ParseError {

For errors during parsing

Variants

ToCST(String)

Error from the lalrpop parser, no additional information

ToAST(String)

Error in the cst -> ast transform, mostly well-formedness issues

WithContext

Fields

context: String

What we were trying to do

errs: Vec<ParseError>

Error(s) we encountered while doing it

(Potentially) multiple errors. This variant includes a “context” for what we were trying to do when we encountered these errors

RestrictedExpressionError(RestrictedExpressionError)

Error concerning restricted expressions

Trait Implementations

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

fn source(&self) -> Option<&(dyn Error + 'static)>

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<L: Display, T: Display, E: Display> From<ErrorRecovery<L, T, E>> for ParseError

fn from(e: ErrorRecovery<L, T, E>) -> Self

Converts to this type from the input type.

impl<L: Display, T: Display, E: Display> From<ParseError<L, T, E>> for ParseError

fn from(e: ParseError<L, T, E>) -> Self

Converts to this type from the input type.

impl From<ParseError> for ParseErrors

fn from(e: ParseError) -> ParseErrors

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 FromIterator<ParseError> for ParseErrors

fn from_iter<T: IntoIterator<Item = ParseError>>(errs: T) -> Self

Creates a value from an iterator.

impl PartialEq<ParseError> for ParseError

fn eq(&self, other: &ParseError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
