Struct intrusive_collections::linked_list::LinkedList [−][src]
pub struct LinkedList<A: Adapter> where
A::LinkOps: LinkedListOps, { /* fields omitted */ }
Expand description
An intrusive doubly-linked list.
When this collection is dropped, all elements linked into it will be converted back to owned pointers and dropped.
Implementations
Creates an empty LinkedList
.
Returns a null CursorMut
for this list.
pub unsafe fn cursor_from_ptr(
&self,
ptr: *const <A::PointerOps as PointerOps>::Value
) -> Cursor<'_, A>
pub unsafe fn cursor_from_ptr(
&self,
ptr: *const <A::PointerOps as PointerOps>::Value
) -> Cursor<'_, A>
Creates a Cursor
from a pointer to an element.
Safety
ptr
must be a pointer to an object that is part of this list.
pub unsafe fn cursor_mut_from_ptr(
&mut self,
ptr: *const <A::PointerOps as PointerOps>::Value
) -> CursorMut<'_, A>
pub unsafe fn cursor_mut_from_ptr(
&mut self,
ptr: *const <A::PointerOps as PointerOps>::Value
) -> CursorMut<'_, A>
Creates a CursorMut
from a pointer to an element.
Safety
ptr
must be a pointer to an object that is part of this list.
Returns a Cursor
pointing to the first element of the list. If the
list is empty then a null cursor is returned.
Returns a CursorMut
pointing to the first element of the list. If the
the list is empty then a null cursor is returned.
Returns a Cursor
pointing to the last element of the list. If the list
is empty then a null cursor is returned.
Returns a CursorMut
pointing to the last element of the list. If the
list is empty then a null cursor is returned.

impl<'a, A: Adapter + 'a> Iterator for Iter<'a, A> where
A::LinkOps: LinkedListOps, type Item = &'a <A::PointerOps as PointerOps>::Value;
Gets an iterator over the objects in the LinkedList
.
Removes all elements from the LinkedList
.
This will unlink all object currently in the list, which requires
iterating through all elements in the LinkedList
. Each element is
converted back to an owned pointer and then dropped.
Empties the LinkedList
without unlinking or freeing objects in it.
Since this does not unlink any objects, any attempts to link these
objects into another LinkedList
will fail but will not cause any
memory unsafety. To unlink those objects manually, you must call the
force_unlink
function on them.
Takes all the elements out of the LinkedList
, leaving it empty.
The taken elements are returned as a new LinkedList
.
Inserts a new element at the start of the LinkedList
.
Inserts a new element at the end of the LinkedList
.
Removes the first element of the LinkedList
.
This returns None
if the LinkedList
is empty.
Removes the last element of the LinkedList
.
This returns None
if the LinkedList
is empty.
