Struct Node 

pub struct Node<N: Clone + Eq + Hash> {
    pub state: N,
    pub parent: Option<Rc<Node<N>>>,
    pub g: f64,
    pub h: f64,
}

A node in the search graph

Fields

state: N

The state represented by this node

parent: Option<Rc<Node<N>>>

The parent node

g: f64

The cost from the start node to this node (g-value)

h: f64

The estimated cost from this node to the goal (h-value)

Implementations

impl<N: Clone + Eq + Hash> Node<N>

pub fn new(state: N, parent: Option<Rc<Node<N>>>, g: f64, h: f64) -> Self

Create a new node

pub fn f(&mut self) -> f64

Get the f-value (f = g + h)

Trait Implementations

impl<N: Clone + Clone + Eq + Hash> Clone for Node<N>

fn clone(&self) -> Node<N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<N: Debug + Clone + Eq + Hash> Debug for Node<N>

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

Formats the value using the given formatter.

impl<N: Clone + Eq + Hash> Ord for Node<N>

fn cmp(&self, other: &Self) -> 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<N: Clone + Eq + Hash> PartialEq for Node<N>

fn eq(&self, other: &Self) -> 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<N: Clone + Eq + Hash> PartialOrd for Node<N>

fn partial_cmp(&self, other: &Self) -> 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.
