Trait collections::dlist::ListInsertionDeprecated

pub trait ListInsertion<A> {
    fn insert_next(&mut self, elt: A);
    fn peek_next<'a>(&'a mut self) -> Option<&'a mut A>;
}

Allows mutating a DList while iterating.

Required Methods

fn insert_next(&mut self, elt: A)

Inserts 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) -> Option<&'a mut A>

Provides a reference to the next element, without changing the iterator
