Trait rayon::par_iter::BoundedParallelIterator

pub trait BoundedParallelIterator: ParallelIterator {
    fn upper_bound(&mut self) -> usize;
}

A trait for parallel iterators items where the precise number of items is not known, but we can at least give an upper-bound. These sorts of iterators result from filtering.

Required Methods

fn upper_bound(&mut self) -> usize
