Struct NodePtrMut 

struct NodePtrMut<'a, V>(*mut Node<V>, PhantomData<&'a mut V>);

A Copy wrapper around *mut Node<V> that serves as the exclusive counterpart to &Node<V> in the NodeRef trait.

The phantom lifetime 'a ties the yielded &'a mut V references back to the original &'a mut MultiIndexed (or &'a mut KdTrie), ensuring soundness.

This is safe to use because:

• It is only constructed from &mut MultiIndexed / &mut KdTrie, guaranteeing exclusive access to the entire tree.
• The tree structure ensures that nodes at different positions are disjoint in memory.
• The iterator yields each value at most once.

Tuple Fields

0: *mut Node<V>

1: PhantomData<&'a mut V>

Trait Implementations

impl<V> Clone for NodePtrMut<'_, V>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, V> NodeRef for NodePtrMut<'a, V>

Exclusive node reference. Yields &mut V values.

type Value = &'a mut V

unsafe fn range(self, is_leaf: bool) -> Range<i32>

Returns the range of indices for this node.

unsafe fn child(self, idx: i32) -> Option<Self>

Returns a handle to the child node at idx, or None if no child exists.

unsafe fn value(self, idx: i32) -> Option<Self::Value>

Returns a reference to the value at idx, or None if the slot is empty.
