Struct Node 

pub struct Node<'a> { /* private fields */ }

A node of a BayesianNetwork.

Implementations

impl<'a> Node<'a>

pub fn name(&self) -> &'a str

The node name.

pub fn parent_names(&self) -> impl ExactSizeIterator<Item = &'a str> + use<'a>

The names of the parents, in CPT level order.

pub fn possible_values( &self, ) -> impl ExactSizeIterator<Item = &'a str> + use<'a>

The values the node can take, in definition order.

pub fn probabilities(&self, parent_values: &Values) -> Vec<(&'a str, f64)>

The distribution of the node given the values of its parents, looked up by name in parent_values (browserforge’s get_probabilities_given_known_values). Empty when the CPT has no entry for those parent values.

pub fn sample(&self, rng: &mut Rng, parent_values: &Values) -> Option<&'a str>

Draws a value given the values of the parents; None when the distribution is empty.

Trait Implementations

impl<'a> Clone for Node<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for Node<'a>

impl Debug for Node<'_>

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

Formats the value using the given formatter.
