Struct Node

pub struct Node {
    pub parent: Option<NodeId>,
    pub previous_sibling: Option<NodeId>,
    pub next_sibling: Option<NodeId>,
    pub first_child: Option<NodeId>,
    pub last_child: Option<NodeId>,
}

Hierarchical information about a node (stores the indicies of the parent / child nodes).

Fields

parent: Option<NodeId>

previous_sibling: Option<NodeId>

next_sibling: Option<NodeId>

first_child: Option<NodeId>

last_child: Option<NodeId>

Trait Implementations

impl Clone for Node

fn clone(&self) -> Node

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Node

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

Formats the value using the given formatter.

impl Default for Node

fn default() -> Node

Returns the “default value” for a type.

impl Hash for Node

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 Ord for Node

fn cmp(&self, other: &Node) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Node

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

impl PartialOrd for Node

fn partial_cmp(&self, other: &Node) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
