pub trait ListInsertion<A> {
fn insert_next(&mut self, elt: A);
fn peek_next<'a>(&'a mut self) -> std::option::Option;
}Allow mutating the DList while iterating
fn insert_next(&mut self, elt: A)Insert elt just after to the element most recently returned by .next()
The inserted element does not appear in the iteration.
fn peek_next<'a>(&'a mut self) -> std::option::OptionProvide a reference to the next element, without changing the iterator
MutDListIterator<'self, A>
