Trait parquet2::read::MutStreamingIterator

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

    fn advance(self) -> Result<State<Self>, Self::Error>;
    fn get(&mut self) -> Option<&mut Self::Item>;
}

A special kind of fallible streaming iterator where advance consumes the iterator.
