Trait astral::thirdparty::rayon::iter::plumbing::UnindexedProducer

pub trait UnindexedProducer: Send {
    type Item;
    fn split(self) -> (Self, Option<Self>);
    fn fold_with<F>(self, folder: F) -> F
    where
        F: Folder<Self::Item>;
}

A variant on Producer which does not know its exact length or cannot represent it in a usize. These producers act like ordinary producers except that they cannot be told to split at a particular point. Instead, you just ask them to split 'somewhere'.

(In principle, Producer could extend this trait; however, it does not because to do so would require producers to carry their own length with them.)
