Trait flag_algebra::iterators::StreamingIterator

pub trait StreamingIterator<A> where
    A: ?Sized, {
    fn next(&mut self) -> Option<&A>;

    fn count(self) -> usize
    where
        Self: Sized,
    { ... }
}

Interface for streaming iterators.

Similarly as in the streaming-iterator crate, the elements yielded by the iterator are borrowed by the iterator. A loop on such an iterator iter is written as follows.

while let Some(item) = iter.next() {
    ...
}

Required methods

fn next(&mut self) -> Option<&A>

Return the next value of the iterator.

Provided methods

fn count(self) -> usize where
    Self: Sized, 

Consume the iterator and return the number of elements yielded.
