Struct intrusive_collections::singly_linked_list::SinglyLinkedList
[−]
[src]
pub struct SinglyLinkedList<A: Adaptor<Link>> { /* fields omitted */ }
An intrusive doubly-linked list.
Methods
impl<A: Adaptor<Link>> SinglyLinkedList<A>[src]
fn new(adaptor: A) -> SinglyLinkedList<A>
Creates an empty SinglyLinkedList.
fn is_empty(&self) -> bool
Returns true if theSinglyLinkedList` is empty.
fn cursor(&self) -> Cursor<A>
Returns a null Cursor for this list.
fn cursor_mut(&mut self) -> CursorMut<A>
Returns a null CursorMut for this list.
unsafe fn cursor_from_ptr(&self, ptr: *const A::Container) -> 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.
unsafe fn cursor_mut_from_ptr(&mut self, ptr: *const A::Container) -> 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.
fn front(&self) -> Cursor<A>
Returns a Cursor pointing to the first element of the list. If the
list is empty then a null cursor is returned.
fn front_mut(&mut self) -> CursorMut<A>
Returns a CursorMut pointing to the first element of the list. If the
the list is empty then a null cursor is returned.
fn iter(&self) -> Iter<A>
Gets an iterator over the objects in the SinglyLinkedList.
fn drain<F>(&mut self, f: F) where F: FnMut(IntrusiveRef<A::Container>)
Calls the given function for each element in the SinglyLinkedList
before removing it from the list.
This will unlink all objects currently in the list.
If the given function panics then all elements in the SinglyLinkedList
will still be unlinked, but the function will not be called for any
elements after the one that panicked.
fn clear(&mut self)
Removes all elements from the SinglyLinkedList.
This will unlink all object currently in the list, which requires
iterating through all elements in the SinglyLinkedList.
fn fast_clear(&mut self)
Empties the SinglyLinkedList without unlinking objects in it.
Since this does not unlink any objects, any attempts to link these
objects into another SinglyLinkedList will fail but will not cause any
memory unsafety. To unlink those objects manually, you must call the
unsafe_unlink function on them.
This is the only function that can be safely called after an object has
been moved or dropped while still being linked into this
SinglyLinkedList.
fn take(&mut self) -> SinglyLinkedList<A> where A: Clone
Takes all the elements out of the SinglyLinkedList, leaving it empty.
The taken elements are returned as a new SinglyLinkedList.
fn push_front(&mut self, val: IntrusiveRef<A::Container>)
Inserts a new element at the start of the SinglyLinkedList.
fn pop_front(&mut self) -> Option<IntrusiveRef<A::Container>>
Removes the first element of the SinglyLinkedList.
This returns None if the SinglyLinkedList is empty.
