Struct antlr_rust::error_strategy::DefaultErrorStrategy
source · [−]pub struct DefaultErrorStrategy<'input, Ctx: ParserNodeType<'input>> { /* private fields */ }Expand description
This is the default implementation of ErrorStrategy used for
error reporting and recovery in ANTLR parsers.

sourcefn reset(&mut self, recognizer: &mut T)
fn reset(&mut self, recognizer: &mut T)
Reset the error handler state for the specified recognizer.
sourcefn recover_inline(
&mut self,
recognizer: &mut T
) -> Result<<T::TF as TokenFactory<'a>>::Tok, ANTLRError>
fn recover_inline(
&mut self,
recognizer: &mut T
) -> Result<<T::TF as TokenFactory<'a>>::Tok, ANTLRError>
This method is called when an unexpected symbol is encountered during an
inline match operation, such as Parser::match. If the error
strategy successfully recovers from the match failure, this method
returns the Token instance which should be treated as the
successful result of the match. Read more
sourcefn recover(
&mut self,
recognizer: &mut T,
_e: &ANTLRError
) -> Result<(), ANTLRError>
fn recover(
&mut self,
recognizer: &mut T,
_e: &ANTLRError
) -> Result<(), ANTLRError>
This method is called to recover from error e. This method is
called after ErrorStrategy::reportError by the default error handler
generated for a rule method. Read more
sourcefn sync(&mut self, recognizer: &mut T) -> Result<(), ANTLRError>
fn sync(&mut self, recognizer: &mut T) -> Result<(), ANTLRError>
This method provides the error handler with an opportunity to handle syntactic or semantic errors in the input stream before they result in a error. Read more
sourcefn in_error_recovery_mode(&mut self, _recognizer: &mut T) -> bool
fn in_error_recovery_mode(&mut self, _recognizer: &mut T) -> bool
Tests whether or not {@code recognizer} is in the process of recovering
from an error. In error recovery mode, Parser::consume will create
ErrorNode leaf instead of TerminalNode one Read more
sourcefn report_error(&mut self, recognizer: &mut T, e: &ANTLRError)
fn report_error(&mut self, recognizer: &mut T, e: &ANTLRError)
Report any kind of ANTLRError. This method is called by
the default exception handler generated for a rule method. Read more
sourcefn report_match(&mut self, recognizer: &mut T)
fn report_match(&mut self, recognizer: &mut T)
This method is called when the parser successfully matches an input symbol. Read more
