{ /* private fields */ }

A cursor over elements in a WavlTree.

Implementations

impl<'a, K, P, Tag, S, O> CursorMut<'a, K, P, Tag, S, O>

where P: PtrTraits, P::Target: WavlTreeContainable<P::Target, Tag> + WavlTreeKeyable<K>, K: Ord, S: SizeTracker, O: WavlTreeObserver<Target = P::Target>,

pub fn get(&self) -> Option<&P::Target>

Returns a reference to the current element.

pub fn move_next(&mut self)

Moves the cursor to the next (larger) element.

pub fn move_prev(&mut self)

Moves the cursor to the previous (smaller) element.

pub fn erase(&mut self) -> Option<P>

Erases the current element and moves the cursor to the next element.
