Struct FilterArgsPred 

pub struct FilterArgsPred {
    pub node: usize,
    pub pred: usize,
    pub root: usize,
    pub depth: usize,
}

Filter arguments for visit that keep track of predecessors.

Fields

node: usize

The current node.

pred: usize

The parent of node in the visit tree, or root if node is the root.

root: usize

The root of the current visit tree.

depth: usize

The depth of the visit, that is, the length of the visit path from the root to node.

Trait Implementations

impl Clone for FilterArgsPred

fn clone(&self) -> FilterArgsPred

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FilterArgsPred

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

Formats the value using the given formatter.

impl Hash for FilterArgsPred

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FilterArgsPred

fn eq(&self, other: &FilterArgsPred) -> 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.
