Implementations

impl Incomplete

pub fn is_unit(&self) -> bool

Whether this “incomplete bound” is the unit type.

Trait Implementations

impl Clone for Incomplete

fn clone(&self) -> Incomplete

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DagLike for &Incomplete

type Node = Incomplete

The type of the DAG node, with no references or wrappers

fn data(&self) -> &Incomplete

A pointer to the underlying data

fn as_dag_node(&self) -> Dag<Self>

Interpret the node as a DAG node

fn left_child(&self) -> Option<Self>

Accessor for the left child of the node, if one exists

fn right_child(&self) -> Option<Self>

Accessor for the right child of the node, if one exists

fn n_children(&self) -> usize

Number of children that the node has.

fn rtl_post_order_iter<S: SharingTracker<SwapChildren<Self>> + Default>( self, ) -> RtlPostOrderIter<Self, S>

Obtains an iterator of all the nodes rooted at the DAG, in right-to-left post order.

fn pre_order_iter<S: SharingTracker<Self> + Default>( self, ) -> PreOrderIter<Self, S>
