Trait Strategy

pub trait Strategy<I: Clone, O, E: Error<I>> {
    // Required method
    fn recover<D: Debugger, P: Parser<I, O, Error = E>>(
        &self,
        recovered_errors: Vec<Located<I, P::Error>>,
        fatal_error: Located<I, P::Error>,
        parser: P,
        debugger: &mut D,
        stream: &mut Stream<'_, I, <P::Error as Error<I>>::Span>,
    ) -> (Vec<Located<I, P::Error>>, Result<(O, Option<Located<I, P::Error>>), Located<I, P::Error>>);
}

A trait implemented by error recovery strategies.

Required Methods

fn recover<D: Debugger, P: Parser<I, O, Error = E>>( &self, recovered_errors: Vec<Located<I, P::Error>>, fatal_error: Located<I, P::Error>, parser: P, debugger: &mut D, stream: &mut Stream<'_, I, <P::Error as Error<I>>::Span>, ) -> (Vec<Located<I, P::Error>>, Result<(O, Option<Located<I, P::Error>>), Located<I, P::Error>>)

Recover from a parsing failure.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
