Implementations§
source§impl<'a, A: Adapter + 'a> Entry<'a, A>where
A::LinkOps: RBTreeOps,
impl<'a, A: Adapter + 'a> Entry<'a, A>where A::LinkOps: RBTreeOps,
sourcepub fn or_insert(
self,
val: <A::PointerOps as PointerOps>::Pointer
) -> CursorMut<'a, A>
pub fn or_insert( self, val: <A::PointerOps as PointerOps>::Pointer ) -> CursorMut<'a, A>
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.
sourcepub fn or_insert_with<F>(self, default: F) -> CursorMut<'a, A>where
F: FnOnce() -> <A::PointerOps as PointerOps>::Pointer,
pub fn or_insert_with<F>(self, default: F) -> CursorMut<'a, A>where F: FnOnce() -> <A::PointerOps as PointerOps>::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.
