Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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<Box<Error<Rule>>> for ParseError

fn from(source: Box<Error<Rule>>) -> ParseError

Converts to this type from the input type.

impl From<GrammarCompositionError> for ParseError

fn from(source: GrammarCompositionError) -> ParseError

Converts to this type from the input type.

impl From<ParseError> for CompilationError

fn from(source: ParseError) -> Self

Converts to this type from the input type.

impl From<ParseError> for ExtensionParseError

fn from(source: ParseError) -> Self

Converts to this type from the input type.
