[−][src]Enum intrusive_collections::rbtree::Entry
An entry in a RBTree
.
See the documentation for RBTree::entry
.
Variants
Occupied(CursorMut<'a, A>)
An occupied entry.
Vacant(InsertCursor<'a, A>)
A vacant entry.
Methods
impl<'a, A: Adapter<Link = Link> + 'a> Entry<'a, A>
[src]
pub fn or_insert(self, val: A::Pointer) -> CursorMut<'a, A>
[src]
Inserts an element into the RBTree
if the entry is vacant, returning
a CursorMut
to the resulting value. If the entry is occupied then a
CursorMut
pointing to the element is returned.
Panics
Panics if the Entry
is vacant and the new element is already linked to
a different intrusive collection.
pub fn or_insert_with<F>(self, default: F) -> CursorMut<'a, A> where
F: FnOnce() -> A::Pointer,
[src]
F: FnOnce() -> A::Pointer,
Calls the given function and inserts the result into the RBTree
if the
entry is vacant, returning a CursorMut
to the resulting value. If the
entry is occupied then a CursorMut
pointing to the element is
returned and the function is not executed.
Panics
Panics if the Entry
is vacant and the new element is already linked to
a different intrusive collection.
