Enum TraversalOrder

pub enum TraversalOrder {
    Skip,
    Stop,
    Continue,
}

Define a data fusion inspired traversal pattern for visiting nodes in a Node, for now only VortexExpr.

This traversal is a pre-order traversal. There are control traversal controls TraversalOrder:

• Skip: Skip visiting the children of the current node.
• Stop: Stop visiting any more nodes in the traversal.
• Continue: Continue with the traversal as expected.

Variants

Skip

In a top-down traversal, skip visiting the children of the current node. In the bottom-up phase of the traversal this does nothing (for now).

Stop

Stop visiting any more nodes in the traversal.

Continue

Continue with the traversal as expected.

Trait Implementations

impl Clone for TraversalOrder

fn clone(&self) -> TraversalOrder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TraversalOrder

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

Formats the value using the given formatter.

impl PartialEq for TraversalOrder

fn eq(&self, other: &TraversalOrder) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
