Struct intrusive_collections::linked_list::CursorMut
[−]
[src]
pub struct CursorMut<'a, A: Adapter<Link = Link> + 'a> { /* fields omitted */ }
A cursor which provides mutable access to a LinkedList.
Methods
impl<'a, A: Adapter<Link = Link>> CursorMut<'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 as_cursor(&self) -> Cursor<A>[src]
Returns a read-only cursor pointing to the current element.
The lifetime of the returned Cursor is bound to that of the
CursorMut, which means it cannot outlive the CursorMut and that the
CursorMut is frozen for the lifetime of the Cursor.
pub fn move_next(&mut self)[src]
Moves the cursor to the next element of the LinkedList.
If the cursor is pointer to the null object then this will move it to
the first element of the LinkedList. If it is pointing to the last
element of the LinkedList then this will move it to the null object.
pub fn move_prev(&mut self)[src]
Moves the cursor to the previous element of the LinkedList.
If the cursor is pointer to the null object then this will move it to
the last element of the LinkedList. If it is pointing to the first
element of the LinkedList 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 LinkedList.
If the cursor is pointer to the null object then this will return the
first element of the LinkedList. If it is pointing to the last
element of the LinkedList then this will return a null cursor.
pub fn peek_prev(&self) -> Cursor<A>[src]
Returns a cursor pointing to the previous element of the LinkedList.
If the cursor is pointer to the null object then this will return the
last element of the LinkedList. If it is pointing to the first
element of the LinkedList then this will return a null cursor.
pub fn remove(&mut self) -> Option<A::Pointer>[src]
Removes the current element from the LinkedList.
A pointer to the element that was removed is returned, and the cursor is
moved to point to the next element in the LinkedList.
If the cursor is currently pointing to the null object then no element
is removed and None is returned.
pub fn replace_with(
&mut self,
val: A::Pointer
) -> Result<A::Pointer, A::Pointer>[src]
&mut self,
val: A::Pointer
) -> Result<A::Pointer, A::Pointer>
Removes the current element from the LinkedList and inserts another
object in its place.
A pointer to the element that was removed is returned, and the cursor is modified to point to the newly added element.
If the cursor is currently pointing to the null object then an error is
returned containing the given val parameter.
Panics
Panics if the new element is already linked to a different intrusive collection.
pub fn insert_after(&mut self, val: A::Pointer)[src]
Inserts a new element into the LinkedList after the current one.
If the cursor is pointing at the null object then the new element is
inserted at the front of the LinkedList.
Panics
Panics if the new element is already linked to a different intrusive collection.
pub fn insert_before(&mut self, val: A::Pointer)[src]
Inserts a new element into the LinkedList before the current one.
If the cursor is pointing at the null object then the new element is
inserted at the end of the LinkedList.
Panics
Panics if the new element is already linked to a different intrusive collection.
pub fn splice_after(&mut self, list: LinkedList<A>)[src]
Inserts the elements from the given LinkedList after the current one.
If the cursor is pointing at the null object then the new elements are
inserted at the start of the LinkedList.
pub fn splice_before(&mut self, list: LinkedList<A>)[src]
Moves all element from the given LinkedList before the current one.
If the cursor is pointing at the null object then the new elements are
inserted at the end of the LinkedList.
pub fn split_after(&mut self) -> LinkedList<A> where
A: Clone, [src]
A: Clone,
Splits the list into two after the current element. This will return a new list consisting of everything after the cursor, with the original list retaining everything before.
If the cursor is pointing at the null object then the entire contents
of the LinkedList are moved.
pub fn split_before(&mut self) -> LinkedList<A> where
A: Clone, [src]
A: Clone,
Splits the list into two before the current element. This will return a new list consisting of everything before the cursor, with the original list retaining everything after.
If the cursor is pointing at the null object then the entire contents
of the LinkedList are moved.
