Struct lrpar::ParseError

pub struct ParseError<LexemeT: Lexeme<StorageT>, StorageT: Hash> { /* private fields */ }

Records a single parse error.

Implementations

impl<LexemeT: Lexeme<StorageT>, StorageT: Hash + PrimInt + Unsigned> ParseError<LexemeT, StorageT>

pub fn stidx(&self) -> StIdx<StorageT>

Return the state table index where this error was detected.

pub fn lexeme(&self) -> &LexemeT

Return the lexeme where this error was detected.

pub fn repairs(&self) -> &Vec<Vec<ParseRepair<LexemeT, StorageT>>>

Return the repairs found that would fix this error. Note that there are infinite number of possible repairs for any error, so this is by definition a (finite) subset.

Trait Implementations

impl<LexemeT: Clone + Lexeme<StorageT>, StorageT: Clone + Hash> Clone for ParseError<LexemeT, StorageT>

fn clone(&self) -> ParseError<LexemeT, StorageT>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<LexemeT: Debug + Lexeme<StorageT>, StorageT: Debug + Hash> Debug for ParseError<LexemeT, StorageT>

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

Formats the value using the given formatter.

impl<LexemeT: Lexeme<StorageT>, StorageT: Debug + Hash> Display for ParseError<LexemeT, StorageT>

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

Formats the value using the given formatter.

impl<LexemeT: Lexeme<StorageT>, StorageT: Debug + Hash> Error for ParseError<LexemeT, StorageT>

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<StorageT: 'static + Debug + Hash + PrimInt + Unsigned, LexerTypesT: LexerTypes<StorageT = StorageT>> From<ParseError<<LexerTypesT as LexerTypes>::LexemeT, StorageT>> for LexParseError<StorageT, LexerTypesT>

where usize: AsPrimitive<StorageT>,

fn from( err: ParseError<LexerTypesT::LexemeT, StorageT>, ) -> LexParseError<StorageT, LexerTypesT>

Converts to this type from the input type.

impl<LexemeT: PartialEq + Lexeme<StorageT>, StorageT: PartialEq + Hash> PartialEq for ParseError<LexemeT, StorageT>

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