Struct bern_kernel::mem::linked_list::Cursor

pub struct Cursor<'a, T, P> where
    P: PoolAllocator<Node<T>> + 'static,  { /* fields omitted */ }

A cursor over a LinkedList with editing operations.

In contrast to an iterator a cursor can move from front to back and take an element out of the list.
