Struct NodeData 

pub struct NodeData {
    pub id: NodeId,
    pub node_type: NodeType,
    pub label: String,
    pub actions: Vec<String>,
    pub children: Vec<NodeId>,
    pub parent: Option<NodeId>,
    pub incoming_action: Option<String>,
}

Data associated with a node in the game tree.

Fields

id: NodeId

Unique identifier for this node.

node_type: NodeType

The type of this node.

label: String

Label for this node (e.g., description of the game state).

actions: Vec<String>

Actions available at this node (labels).

children: Vec<NodeId>

Children node IDs, one per action.

parent: Option<NodeId>

Parent node ID (None for root).

incoming_action: Option<String>

The action label that led to this node from its parent.

Implementations

impl NodeData

pub fn decision(id: NodeId, player: PlayerId, label: &str) -> Self

Create a new decision node.

pub fn chance(id: NodeId, probabilities: Vec<f64>, label: &str) -> Self

Create a chance node.

pub fn terminal(id: NodeId, payoffs: Vec<Payoff>, label: &str) -> Self

pub fn is_terminal(&self) -> bool

Is this a terminal node?

pub fn is_decision(&self) -> bool

pub fn player(&self) -> PlayerId

Get the player at this decision node (panics if not a decision node).

pub fn payoffs(&self) -> &[Payoff]

Get payoffs at this terminal node (panics if not terminal).

pub fn num_actions(&self) -> usize

Get the number of actions at this node.
