Trait TryAcc

pub trait TryAcc: Sized {
    type Error;
    type Item;

    // Required method
    fn try_acc(self, item: Self::Item) -> Result<Self, Self::Error>;
}

This is very usefull to be use on combinator like try_fold. For example, .try_fold_bounds(.., || Ok(Vec::new), TryAcc::try_acc).

Required Associated Types
