Struct Chance 

pub struct Chance<'a, 'g> { /* private fields */ }

A chance node

A chance node represents a point in the game where things advance randomly, or alternatively, where “nature” takes a turn.

Implementations

impl<'a, 'g> Chance<'a, 'g>

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

The name of the node

pub fn infoset(self) -> u64

The id of the node’s infoset

pub fn infoset_name(self) -> &'a EscapedStr

The infoset’s label

pub fn actions( self, ) -> impl Iterator<Item = (&'a EscapedStr, &'g BigRational, Node<'a, 'g>)> + 'g

All possible actions with their names, probabilities, and resulting nodes

pub fn action( self, label: &EscapedStr, ) -> Option<(&'g BigRational, Node<'a, 'g>)>

The probability and child for the action with the given label

Labels need not be unique within an infoset, so this returns the first match.

pub fn len(self) -> usize

The number of actions (always at least one)

pub fn action_at( self, index: usize, ) -> Option<(&'a EscapedStr, &'g BigRational, Node<'a, 'g>)>

The name, probability, and child for the action at the given index

pub fn outcome(self) -> u64

The outcome id

pub fn outcome_payoffs(self) -> Option<&'g [BigRational]>

Outcome payoffs for this node

Outcome payoffs are added to every players’ payoffs for traversing through this node. Note that if these are missing, they be defined at another node sharing the same outcome.

Trait Implementations

impl<'a, 'g> Clone for Chance<'a, 'g>

fn clone(&self) -> Chance<'a, 'g>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, 'g> Copy for Chance<'a, 'g>

impl Display for Chance<'_, '_>

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

Formats the value using the given formatter.
