Trait flatk::RemovePrefix

pub trait RemovePrefix {
    fn remove_prefix(&mut self, n: usize);
}

A helper trait used to help implement the Subset. This trait allows abstract collections to remove a number of elements from the beginning, which is what we need for subsets.

Required methods

fn remove_prefix(&mut self, n: usize)

Remove n elements from the beginning.
