Struct Variable 

pub struct Variable {
    pub id: VariableId,
    pub name: String,
    pub states: Vec<String>,
}

A discrete random variable with named states.

Example

use cvx_bayes::Variable;

let task = Variable::new(0, "task_type", vec![
    "pick_and_place".into(),
    "heat_then_place".into(),
    "clean_then_place".into(),
]);
assert_eq!(task.n_states(), 3);
assert_eq!(task.state_index("heat_then_place"), Some(1));

Fields

id: VariableId

Unique ID in the network.

name: String

Human-readable name.

states: Vec<String>

Named states (e.g., [“success”, “failure”]).

Implementations

impl Variable

pub fn new(id: VariableId, name: impl Into<String>, states: Vec<String>) -> Self

Create a new variable with named states.

pub fn binary(id: VariableId, name: impl Into<String>) -> Self

Create a binary variable (two states: “true”, “false”).

pub fn n_states(&self) -> usize

Number of states.

pub fn state_index(&self, state_name: &str) -> Option<usize>

Get state index by name.

pub fn state_name(&self, index: usize) -> Option<&str>

Get state name by index.
