Trait pahs::error_accumulator::ErrorAccumulator

pub trait ErrorAccumulator<P, E> {
    type Accumulated;
    pub fn add_err(&mut self, err: E, pos: P);
    pub fn finish(self) -> Self::Accumulated;

    pub fn add_progress<T>(
        &mut self, 
        progress: Progress<P, T, E>
    ) -> Progress<P, T, ()>
    where
        P: Clone,
    { ... }
}

Allows tracking multiple failures encountered in complex parsers or combinators.
