I have a KdTree with indices to Vec<Slot> because Slot is too large to be efficiently stored directly in the KdTree. When removing an entity, one can efficiently remove it from the Vec with Vec::swap_remove(index) which moves the last slot to index. This creates the need to change the stored index inside KdTree of the moved item.
Add a method to exchange a value of a point.
Use case:
I have a
KdTree
with indices toVec<Slot>
becauseSlot
is too large to be efficiently stored directly in the KdTree. When removing an entity, one can efficiently remove it from the Vec withVec::swap_remove(index)
which moves the last slot toindex
. This creates the need to change the stored index inside KdTree of the moved item.
