Enum TraversalOrder

pub enum TraversalOrder {
    Skip,
    Stop,
    Continue,
}

Signal to control a traversal’s flow

Variants

Skip

In a top-down traversal, skip visiting the children of the current node. In the bottom-up phase of the traversal, skip the next step. Either skipping the children of the node, moving to its next sibling, or skipping its parent once the children are traversed.

Stop

Stop visiting any more nodes in the traversal.

Continue

Continue with the traversal as expected.

Implementations

impl TraversalOrder

pub fn visit_children<F: FnOnce() -> VortexResult<TraversalOrder>>( self, f: F, ) -> VortexResult<TraversalOrder>

If directed to, continue to visit nodes by running f, which should apply on the node’s children.

pub fn visit_parent<F: FnOnce() -> VortexResult<TraversalOrder>>( self, f: F, ) -> VortexResult<TraversalOrder>

If directed to, continue to visit nodes by running f, which should apply on the node’s parent.

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.
