Enum intrusive_collections::rbtree::Entry
source · pub enum Entry<'a, A: Adapter<Link = Link> + 'a> {
Occupied(CursorMut<'a, A>),
Vacant(InsertCursor<'a, A>),
}Expand description
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.
Implementations
sourceimpl<'a, A: Adapter<Link = Link> + 'a> Entry<'a, A>
impl<'a, A: Adapter<Link = Link> + 'a> Entry<'a, A>
sourcepub fn or_insert(self, val: A::Pointer) -> CursorMut<'a, A>
pub fn or_insert(self, val: A::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::Pointer,
pub fn or_insert_with<F>(self, default: F) -> CursorMut<'a, A>where
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.
