[−][src]Struct intrusive_collections::singly_linked_list::Cursor
A cursor which provides read-only access to a SinglyLinkedList
.
Methods
impl<'a, A: Adapter<Link = Link>> Cursor<'a, A>
[src]
pub fn is_null(&self) -> bool
[src]
Checks if the cursor is currently pointing to the null object.
pub fn get(&self) -> Option<&'a A::Value>
[src]
Returns a reference to the object that the cursor is currently pointing to.
This returns None if the cursor is currently pointing to the null object.
pub fn move_next(&mut self)
[src]
Moves the cursor to the next element of the SinglyLinkedList
.
If the cursor is pointer to the null object then this will move it to
the first element of the SinglyLinkedList
. If it is pointing to the
last element of the SinglyLinkedList
then this will move it to the
null object.
pub fn peek_next(&self) -> Cursor<A>
[src]
Returns a cursor pointing to the next element of the SinglyLinkedList
.
If the cursor is pointer to the null object then this will return the
first element of the SinglyLinkedList
. If it is pointing to the last
element of the SinglyLinkedList
then this will return a null cursor.
