[][src]Struct intrusive_collections::xor_linked_list::CursorMut

pub struct CursorMut<'a, A: Adapter> where
    A::LinkOps: XorLinkedListOps
{ /* fields omitted */ }

A cursor which provides mutable access to a XorLinkedList.

Implementations

impl<'a, A: Adapter> CursorMut<'a, A> where
    A::LinkOps: XorLinkedListOps
[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::PointerOps as PointerOps>::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 XorLinkedList.

If the cursor is pointer to the null object then this will move it to the first element of the XorLinkedList. If it is pointing to the last element of the XorLinkedList 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 XorLinkedList.

If the cursor is pointer to the null object then this will move it to the last element of the XorLinkedList. If it is pointing to the first element of the XorLinkedList 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 XorLinkedList.

If the cursor is pointer to the null object then this will return the first element of the XorLinkedList. If it is pointing to the last element of the XorLinkedList 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 XorLinkedList.

If the cursor is pointer to the null object then this will return the last element of the XorLinkedList. If it is pointing to the first element of the XorLinkedList then this will return a null cursor.

pub fn remove(&mut self) -> Option<<A::PointerOps as PointerOps>::Pointer>[src]

Removes the current element from the XorLinkedList.

A pointer to the element that was removed is returned, and the cursor is moved to point to the next element in the XorLinkedList.

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::PointerOps as PointerOps>::Pointer
) -> Result<<A::PointerOps as PointerOps>::Pointer, <A::PointerOps as PointerOps>::Pointer>
[src]

Removes the current element from the XorLinkedList 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::PointerOps as PointerOps>::Pointer)[src]

Inserts a new element into the XorLinkedList after the current one.

If the cursor is pointing at the null object then the new element is inserted at the front of the XorLinkedList.

Panics

Panics if the new element is already linked to a different intrusive collection.

pub fn insert_before(&mut self, val: <A::PointerOps as PointerOps>::Pointer)[src]

Inserts a new element into the XorLinkedList before the current one.

If the cursor is pointing at the null object then the new element is inserted at the end of the XorLinkedList.

Panics

Panics if the new element is already linked to a different intrusive collection.

pub fn splice_after(&mut self, list: XorLinkedList<A>)[src]

Inserts the elements from the given XorLinkedList after the current one.

If the cursor is pointing at the null object then the new elements are inserted at the start of the XorLinkedList.

pub fn splice_before(&mut self, list: XorLinkedList<A>)[src]

Moves all element from the given XorLinkedList before the current one.

If the cursor is pointing at the null object then the new elements are inserted at the end of the XorLinkedList.

pub fn split_after(&mut self) -> XorLinkedList<A> where
    A: Clone
[src]

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 XorLinkedList are moved.

pub fn split_before(&mut self) -> XorLinkedList<A> where
    A: Clone
[src]

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 XorLinkedList are moved.
