pub struct MoveEvent<'a, T> {
    pub target_leaf: Option<ArenaIndex>,
    pub elem: &'a T,
}
Expand description

The move event of an element.

It’s used to track the which leaf node an element is in.

The delete events are not guaranteed to be called. The events are missing when:

  • The tree is dropped
  • Or, when draining a range, the elements from the start/end leaf node

Fields§

§target_leaf: Option<ArenaIndex>

If this is None, it means the element is deleted from the tree

§elem: &'a T
