Trait resiter::filter::Filter

pub trait Filter<O, E>: Sized {
    fn filter_ok<F>(self, _: F) -> FilterOk<Self, F> 
    where
        F: FnMut(&O) -> bool;
    fn filter_err<F>(self, _: F) -> FilterErr<Self, F> 
    where
        F: FnMut(&E) -> bool;
}

Extension trait for Iterator<Item = Result<O, E>> to filter one kind of result (and leaving the other as is)
