Enum NodeView 

pub enum NodeView<'a, const D: usize> {
    Internal(&'a InternalData<D>),
    Leaf(&'a LeafData),
}

Zero-copy immutable view of a tree node. Returned by crate::NodeStore::view — pattern-match to branch on internal-vs-leaf without cloning the underlying record.

Variants

Internal(&'a InternalData<D>)

Reference to an internal node’s record.

Leaf(&'a LeafData)

Reference to a leaf node’s record.

Implementations

impl<const D: usize> NodeView<'_, D>

pub fn mass(&self) -> u64

Mass of the node (leaf count for internals, copy count for leaves).

pub fn parent(&self) -> Option<NodeRef>

Parent reference (None only for the root).

pub fn is_internal(&self) -> bool

Whether this is an internal node.

pub fn is_leaf(&self) -> bool

Whether this is a leaf.

Trait Implementations

impl<'a, const D: usize> Debug for NodeView<'a, D>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
